Every home's wiring tells a different story, and after nearly four decades of work across Tustin and Orange County, we've heard just about all of them. Ponderosa Electric has been serving this community since 1989, handling everything from a single tripped breaker to full commercial electrical installations. Whether you need something repaired today or want to plan a larger project, we're ready to take the call.
We work with homeowners, landlords, property managers, and local businesses. Residential repairs, panel upgrades, new construction wiring, commercial tenant improvements -- we handle the full range. Same-day appointments are available for urgent situations, and we can work around your schedule for planned projects.
Know the price. Know the arrival window. Know your electrician.
When you call, a real local person answers. We'll talk through what you're seeing, give you a straight answer on next steps, and get a licensed electrician to your door without the runaround. Clear communication from the first call to the final test is how we've kept customers coming back since the late eighties.
The hardest part of an electrical problem is knowing when to call, and the honest answer is: sooner is better. Flickering lights, outlets that stopped working, breakers that trip repeatedly, and circuits that run warm to the touch are all signs something needs attention. Left alone, wiring faults can become safety hazards.
Our troubleshooting process starts with a real diagnosis. We trace the problem to its source rather than swapping parts until something works. If your home needs updated GFCI outlet protection in the kitchen or bathrooms, or AFCI circuit protection in bedrooms and living areas, we'll explain why and handle the installation properly. Experienced electricians who respect your home show up prepared, work clean, and leave the space the way they found it.
We'll make your wiring safe again.
From a single GFCI outlet to a whole-home rewire, we've seen it all, and outlet and switch work is some of the most common service we provide. Standard outlet replacement, GFCI and AFCI outlets, 240V outlets for appliances, dimmer switches, and smart switch wiring are all in a day's work.
On the lighting side, we install recessed LED lighting, replace outdated fixtures, and run wiring for ceiling fans throughout the home. Outside, we handle weatherproof outlets, security lighting, motion sensor lights, and landscape lighting circuits. Whether it's a single fixture swap or a full exterior lighting plan for a rental property, we'll get it done right.
Pick up the phone and we'll handle the wiring.
Older homes in the Tustin area often carry 100-amp panels that were sized for a different era. Today's homes run more circuits, more appliances, and more electronics than those panels were ever designed to support. We handle 100-to-200 amp service upgrades, service-entrance work, and meter upgrades to bring your home's capacity in line with how you actually use it.
Dedicated appliance circuits are a common add-on during panel work. If you're running a dryer, a refrigerator, a workshop compressor, or a garage freezer off a shared circuit, you're asking for nuisance trips and potential wear on the wiring. We install dedicated circuits for kitchens, laundry rooms, garages, and workshops, and we pull the permits to keep the work code-compliant.
Remodels, home additions, and accessory dwelling units often need a subpanel to serve the new space cleanly. We run load calculations, size the subpanel correctly, and wire it to current code so the inspector passes it on the first visit.
Leave the breakers to us.
Keeping a home safe starts with the wiring behind the walls, and in a city with housing stock that spans several decades, what's behind those walls varies widely. Knob-and-tube wiring from older construction is a fire risk and an insurance problem. Aluminum branch circuit wiring from the sixties and seventies requires proper remediation at every connection point to prevent overheating. We handle both, replacing old systems with modern copper wiring and grounding that meets current code.
Remodel wiring, home addition circuits, and new construction rough-in are all work we take on regularly. If you're preparing a home for sale and need a pre-sale electrical inspection or a code violation corrected before closing, we can move quickly. We pull permits, work to code, and document the work so there are no surprises at inspection.
We take pride in the electrical work we leave behind. Every job we close out is one we'd stand behind years down the road, because in a community this size, our work speaks for itself.
Tustin and the broader Orange County area have a specific set of electrical demands that go beyond the basics. A mild climate keeps heating and cooling loads moderate, but EV ownership here leads the state, rooftop solar is on a significant share of local homes, and wildfire-season public-safety power shutoffs have made grid reliability a real concern. The services below reflect what local homeowners and property managers are actually asking for.
Orange County has one of the highest concentrations of electric vehicles in the country, and Level 2 home charging is the practical standard for daily use. A Level 2 charger requires a dedicated 240V circuit, a panel with available capacity, and wiring run to the right location in your garage or driveway. We assess your panel first, handle any capacity upgrade needed, and install the circuit and outlet or hardwired connection to match your charger. The result is a safe, code-compliant setup that charges your vehicle overnight without stressing the rest of your electrical system.
Year-round sun and rising utility rates have made rooftop solar a common sight across Tustin neighborhoods. Our role is the electrical side: verifying that your panel can handle the inverter load, running dedicated circuits, and completing the interconnection wiring between your solar system, battery storage, and your home's main service. If your panel needs an upgrade or a subpanel to support the installation, we handle that too. With grid outages becoming a seasonal reality during high-fire-risk periods, battery backup systems have moved from a luxury to a practical decision for many households.
Summer heat events push the regional grid hard, and utility switching during those periods sends voltage spikes through the lines. Modern homes carry a lot of sensitive electronics, and homes with solar inverters and EV chargers have even more at stake. A whole-home surge protector installed at the main panel intercepts those spikes before they reach your devices, your appliances, and your solar equipment. It's a straightforward installation that protects a significant investment.
We work across property types and customer types. Single-family homes, condos, apartments, and ADUs on the residential side. Offices, retail spaces, and rental properties on the commercial side. Property managers and landlords come to us regularly for electrical inspections on units between tenants, code compliance work to keep properties lease-ready, and repairs that need to happen on a tight timeline.
Pre-purchase electrical inspections give buyers a clear picture of what they're taking on. Pre-sale inspections help sellers get ahead of issues before they become negotiating problems. We also wire smoke detectors and carbon monoxide detectors, run dedicated circuits for hot tubs, spas, and pool equipment, and handle garage and workshop wiring for customers who need serious capacity in those spaces.
Right diagnosis. Right wiring. Right the first time.
Electrical pricing questions are fair questions, and we answer them directly. The cost of a panel upgrade, an outlet installation, a safety inspection, or a rewiring project depends on what's there now and what the work actually involves. We look at the job, give you a clear number, and don't add to it later without a conversation first.
Same-day availability means urgent problems don't have to wait. Scheduled work gets a firm arrival window so you're not clearing your calendar for a vague four-hour block. Call for a quote and we'll walk you through what the job involves and what it will cost before any work begins.
We're based in Tustin and work throughout Orange County. The area's mix of older neighborhoods with mid-century wiring and newer developments with modern panels and EV-ready garages keeps our schedule varied and our team sharp. If you're in a neighboring community, there's a good chance we've already worked on your street.
We regularly serve:
If you're nearby and not on this list, call anyway. We cover the wider region and can let you know quickly whether we're the right fit.
We test every circuit, outlet, and connection we touched before we close up and pack out. For panel work, that includes verifying breaker operation and confirming proper voltage at the affected circuits. We do not consider a job finished until the work has been tested and confirmed to be operating correctly.
Yes. Panel upgrades, service entrance work, new circuit installations, and rewiring projects typically require permits in Orange County. We pull the permits, schedule the inspection, and make sure the work is ready to pass on the first visit. You do not have to manage that process yourself.
We start with an assessment of what is there and a clear explanation of why replacement is the right path. From there, we give you a written scope and price, pull the required permits, and schedule the work in a sequence that minimizes the time your power is off. After the work is done, we coordinate the inspection and confirm the new system is operating correctly before we close out the job.
We look at the symptoms, trace the circuit or wiring involved, and assess the condition of the panel and related components. For larger jobs, a load calculation helps us size circuits and panels correctly for what the home or building is actually running. We explain what we found and what the options are before we recommend a course of action.
Homes built decades ago were wired for far fewer electrical loads than modern households run. A 100-amp panel with circuits shared across multiple rooms was standard at the time. Today, the same panel is often carrying appliances, home office equipment, EV chargers, and entertainment systems it was never designed to support. Adding circuits or upgrading the panel resolves the problem at the source.
A burning smell from a panel, outlet, or fixture, a breaker that trips immediately after being reset, power loss that cannot be explained by the utility, or any visible sparking or scorching around electrical equipment should be treated as urgent. Call us right away rather than waiting to see if the problem resolves on its own.
A whole-home surge protector installs at the main panel and intercepts voltage spikes before they travel through your circuits to your appliances and electronics. It is not the same as a power strip. It protects every outlet and hardwired appliance in the home simultaneously. In Southern California, where grid stress during summer heat events and utility switching during high-fire-risk periods can send spikes through the lines, it is a practical layer of protection for any home.
We test the circuit and the charger connection before we leave to confirm the unit is drawing power correctly and the circuit is within spec. We walk you through the setup so you know how the charger operates and what to watch for. The installation is permitted and inspected, so you have documentation that the work was done to code.
Our role is the electrical infrastructure side of a solar or battery installation. We verify that your panel has the capacity to handle the inverter load, run the dedicated circuits required, and complete the interconnection wiring between the solar system, battery storage, and your main service. If the panel needs an upgrade to support the system, we handle that as part of the project.
An outlet that sparks when you plug something in, a switch that buzzes or feels warm, a receptacle that does not hold a plug firmly, or a switch that does not consistently turn a fixture on are all signs of a connection problem. These are repair jobs, not things to live with, because a loose or failing connection can overheat over time.
For most circuit-level work, we shut off the affected circuit at the panel. For panel work itself, we shut off the main breaker or coordinate with the utility if the service entrance needs to be de-energized. We plan the sequence to keep the outage as short as possible and let you know in advance what will be without power and for how long.
We assess the existing system against current California electrical code, identify what needs to be corrected, and give you a clear picture of the scope before work begins. Corrections are done with proper permits where required, and we document the work so there is a record of what was updated and when. The goal is a system that is safe and will pass inspection.
We've been doing this work in Tustin since 1989, and the approach hasn't changed: show up when we say we will, do the work right, and leave your home or business in better shape than we found it. Locally owned, personally accountable, and ready to take your call.
Schedule it. We wire it. You're powered.

We handle the full range of electrical work for Tustin homes and businesses, from a single tripped breaker to a complete service upgrade. Every job comes with a clear price before work begins and is performed by licensed electricians who know Orange County's code requirements. The table below lays out what each service covers, who it fits best, and a practical note to help you decide where to start. Call us when you are ready and we will get you scheduled.
| Service | What It Covers | When You Need It | Good to Know |
|---|---|---|---|
| Lighting Installation |
| homeowners updating interior or exterior lighting for safety or aesthetics | Outdoor lighting in Southern California's climate takes real UV and heat exposure. We use fixtures and wiring methods rated for the conditions. |
| Breaker & Fuse Repair |
| homes where a breaker will not hold or keeps tripping after reset | A breaker that trips immediately after reset usually points to a fault in the circuit, not just the breaker itself. We trace both before recommending a fix. |
| Electrical Repairs & Troubleshooting |
| homeowners noticing something off with their power | A proper diagnostic traces the fault to its source rather than masking the symptom. Warm outlets or a burning smell near a panel are urgent situations. |
| Electrical Safety Inspections |
| buyers, landlords, and property managers who need to know what they have before a problem develops | An inspection before a home purchase or tenant buildout can surface wiring issues that are far cheaper to address before they become urgent repairs. |
| Hot-Tub Circuits |
| homeowners installing a hot tub or spa that requires its own protected circuit | Hot tub wiring requires a dedicated circuit, a code-compliant disconnect within sight of the unit, and GFCI protection. We pull the permit and schedule the inspection so the installation is done to code. |
| Wiring & Rewiring |
| older homes with outdated wiring systems that were never updated | Aluminum branch circuit wiring and knob-and-tube systems carry real risks when left unaddressed. We assess what is there, explain what it means, and give you options before any work begins. |
| Dedicated Appliance Circuits |
| homeowners adding a major appliance or workshop that needs its own protected line | A dedicated circuit keeps the rest of your home's power stable and protects the appliance from sharing a line with other loads. We size the circuit to the appliance's actual requirements. |
| Standby Battery for Outages |
| households that want backup power during public-safety shutoffs or grid outages | We handle the electrical side: the transfer switch, the dedicated circuit feeding the battery system, and any panel work needed to integrate it safely. We do not supply or install the battery hardware itself. |
| EV Charger Installation |
| Orange County EV owners who want reliable overnight charging at home | California leads the nation in EV adoption, and Orange County is one of the most EV-dense counties in the state. If your panel does not have room for the added load, we handle that upgrade before the charger goes in. |
| Solar & Battery Backup |
| Tustin homeowners adding rooftop solar or a battery storage system | We handle the electrical infrastructure side of a solar installation: panel capacity, dedicated circuits for battery systems, and service upgrades when the existing panel cannot support the system. We do not install solar panels or battery hardware. |
| Older-Home Rewiring |
| pre-1970s homes that have never had their wiring updated | Many older Tustin homes still carry wiring systems that were not designed for today's electrical loads. We assess the full picture and give you a realistic scope before recommending a full or partial rewire. |
| Ceiling Fan Installation |
| rooms that never had a fan or need a fan-rated ceiling box installed | A standard ceiling box is not rated to hold a spinning fan. If the room does not already have a fan-rated box, we install one before the fan goes up. |
| Whole-Home Surge Protection |
| homes in areas subject to grid stress, public-safety power shutoffs, or frequent outages | Southern California's wildfire-season power shutoffs followed by sudden restoration can send voltage spikes through a home's wiring. A panel-level surge protector absorbs those spikes before they reach your equipment. |
| Outlet & Switch Installation |
| kitchens, bathrooms, garages, and outdoor areas requiring code-compliant receptacles | Current code requires GFCI protection in kitchens, bathrooms, garages, and all outdoor locations. A GFCI that trips constantly or will not reset is a repair job, not just a nuisance. |
| Electrical Panel & Service UpgradesMost Popular |
| homes with older fuse boxes, 100-amp panels, or panels running out of circuit capacity | Panel upgrades require permits and inspection in Orange County. Work is performed by licensed electricians who pull the proper permits and coordinate with the utility when the service entrance needs to grow. |
How do I know if my panel needs to be upgraded?
A few signs point clearly in that direction: breakers that trip often, a fuse box that has never been replaced, a 100-amp service that cannot keep up with your current appliances, or a panel that runs warm or has no room for new circuits. If you are adding an EV charger, a battery storage system, or a major appliance and the panel is already near capacity, an upgrade is usually part of the conversation. Call us and we will walk through what you have.
What causes a breaker to keep tripping?
A breaker trips when it detects more current than the circuit is rated to carry, or when it senses a fault in the wiring. Occasional tripping on a heavily loaded circuit is normal. A breaker that trips repeatedly, or that will not hold after you reset it, usually means there is a fault somewhere in the circuit or the breaker itself is failing. Either way, that is a situation worth a call rather than something to reset and ignore.
Is electrical work in Tustin permitted and inspected?
Most electrical work beyond simple fixture swaps requires a permit and inspection in Orange County. Panel upgrades, new circuits, service-entrance work, EV charger installations, and hot tub wiring all fall into that category. We pull the proper permits and schedule inspections as part of the job, so the work is documented and code-compliant when it is done.
Transparent Upfront Pricing
We give you a clear price before any work begins. If we open a wall or panel and find something that changes the scope, we stop and talk through the options before proceeding. You decide how to move forward.
Is the wiring in an older home safe?
It depends on what is there and how it has been maintained. Knob-and-tube wiring and aluminum branch circuit wiring both carry risks when left unaddressed, particularly if they have been modified over the years by people who did not understand the system. An inspection gives you a clear picture of what you have. We assess older wiring regularly in Tustin and can explain what we find without overselling the scope of work needed.
What does installing a home EV charger actually involve?
A Level 2 home charger runs on a dedicated 240-volt circuit, similar to what a dryer uses. We start by checking your panel's available capacity, then run the circuit from the panel to the garage or driveway, and mount and connect the charger. If the panel does not have room for the added load, we address that before the charger goes in. The whole job usually takes a day or less once the permit is in hand.
Why do outlets and switches stop working?
The most common reasons are a tripped GFCI outlet upstream on the circuit, a loose wiring connection at the device or in the box, or a failed outlet or switch that has simply worn out. In older homes, wiring connections can work loose over decades of thermal cycling. We trace the circuit, find the cause, and fix it at the source rather than just swapping the device and hoping for the best.
Work Performed by Licensed Electricians
Every job is handled by licensed electricians who know Orange County's code requirements and take the inspection process seriously. Clear communication from the first call to the final test is how we do things.
What do flickering or dimming lights usually mean?
Flickering that happens when a large appliance cycles on, such as a refrigerator or air conditioner, often points to a shared circuit that is carrying more load than it should. Flickering that happens on its own, or that affects multiple rooms, can indicate a loose connection, a failing breaker, or a problem with the utility feed coming into the home. Persistent flickering is worth a call, especially if it is getting worse.
Is a warm or buzzing outlet something to worry about?
Yes. An outlet that feels warm to the touch or makes a buzzing or crackling sound is not behaving normally. Warmth can mean a loose connection, an overloaded circuit, or a failing device. Buzzing often points to arcing inside the box. Both situations can become fire hazards if left alone. Stop using the outlet and call us.
Experienced With Older and Newer Homes
We work on homes from every era in Tustin, from pre-1970s houses with outdated wiring systems to newer builds adding EV chargers and battery backup. Whatever the wiring situation, we assess it honestly and give you real options.
Can you add circuits for a workshop or large appliance?
Yes, and it is one of the more common jobs we do. A dedicated circuit gives a workshop, a new appliance, or a charging station its own protected line so it does not compete with the rest of the home's power. We size the circuit to the load, run the wiring, and add the breaker. If the panel does not have room, we discuss your options before any work begins.
Do I need to be home when the electrician arrives?
For most jobs, yes. An adult needs to be present to give access, review the work area, and approve the price before we start. If you are a property manager coordinating access for a rental unit, call us and we will work out a plan that fits the situation.
Is same-day service available for urgent electrical problems?
We take same-day calls and respond promptly to urgent situations. After-hours and weekend availability means you are not left waiting until Monday for an answer. When you call, let us know what is happening and we will do our best to get someone out the same day.
Every home and business has a different electrical situation, and the best way to get a straight answer is to call us and describe what you are seeing. We will talk through the job, let you know what to expect, and get you scheduled.
