Today's homes draw more power than ever, and a 100-amp service that once felt generous can leave you out of room the moment you add an EV charger or a heat pump. GTZ Electric performs 200 amp panel upgrades for homeowners in Los Osos, Pismo Beach, Paso Robles, and across San Luis Obispo County, giving your home the headroom that modern living requires. We size the new service, install the panel, coordinate with the utility, and handle inspection, so you can add the loads you want without a second thought.
When a home outgrows its electrical service, GTZ Electric steps in as the licensed, owner-operated contractor for Baywood-Los Osos, California, and the surrounding San Luis Obispo County communities. The company specializes in 200 amp panel upgrades, raising residential and light commercial service to the capacity that EV chargers, electric heating, and modern appliances demand. Guided by owner Ozi Gutierrez and the slogan systems tailored to your needs, GTZ Electric installs 200-amp panels from Siemens, Square D, and Eaton and coordinates the utility changeover for a clean, code-compliant result.
For decades, a 100-amp service was plenty. It powered the lights, the kitchen, the laundry, and a furnace without breaking a sweat, so countless homes were built and wired around it.
The way we use electricity has changed faster than those panels were meant to keep up with. An EV charger alone can claim a large share of a 100-amp service, and adding electric heating, a larger air conditioner, or a workshop pushes the total past what the service can safely carry. The signs show up as a main breaker that trips under heavy use, a panel with no room for new circuits, and the nagging sense that the home cannot take on anything more. A service stretched to its limit runs hot and leaves no margin for safety.
We approach a 200-amp upgrade by starting with the numbers. A load calculation tells us what your home actually draws and what it will need as you add equipment, so the new service is sized with the future in mind. Homes around Los Osos and Paso Robles vary in age and wiring, so we check the condition of the service entrance, the grounding, and the meter base as part of the job. Because raising the service usually involves the utility, we coordinate the disconnect and reconnect so the upgrade goes smoothly.
With 200 amps in place, the ceiling that held your home back is gone. The main breaker stops tripping under load, the panel has open slots for new circuits, and you can add an EV charger, a heat pump, or a shop without straining the service. The upgrade turns a home that was running out of power into one ready for whatever you plug in next.
Doubling your service does more than stop nuisance trips. Here is what a 200-amp upgrade makes possible.
A 200 amp panel upgrade gives your home the headroom to run EV chargers, heat pumps, and electric appliances together without overloading the service.
A larger panel comes with the slots you need to add circuits down the road, so future projects do not mean starting over.
With double the amperage, your main breaker stops tripping when several large loads run at once, and the service stays within safe limits.
We base the upgrade on a load calculation, so your new 200-amp service fits how you actually use power rather than a rough guess.
We coordinate the utility, pull the permits, arrange inspection, and back the work with a one-year parts and labor warranty.
A 200-amp upgrade is one path to more power. These related services cover the others.
Not every home needs a full 200-amp service. Our Electrical Panel Upgrade service replaces aging panels and fuse boxes with modern, code-compliant equipment at the right capacity.
When the main panel has the capacity but you need circuits elsewhere, our Subpanel Installation service extends power to a garage, shop, or addition.
Our broader Panel Replacements and Upgrades work covers meter upgrades, service changes, and full replacements tailored to your property.
Raising a home's service is detailed work, and how it is done shows. Here is what sets our 200-amp upgrades apart.
Ozi Gutierrez leads GTZ Electric and stays close to service upgrades, so a job this significant is overseen by the owner himself.
We run a real load calculation and ask about your plans, so the new service accounts for the EV charger or heat pump you have in mind, not just today's load.
A free Liveswitch video assessment lets us review your panel and service entrance and give early pricing, often without an in-person visit.
We install 200-amp panels from Siemens, Square D, and Eaton, built for the demands of a fully loaded modern home.
Our customers describe their experience on Yelp, Home Advisor, Angie's List, and Nextdoor, where you can see how we handle major service work.
If your main breaker trips under heavy use, your panel is full, or you are planning an EV charger or heat pump, a 200-amp service is often the answer. A load calculation confirms what your home needs.
In most cases, yes. A 200-amp service usually provides the headroom an EV charger requires, which is one of the most common reasons homeowners in the Los Osos area upgrade.
Often it does, since raising the service can mean changes at the meter and service entrance. We coordinate the disconnect and reconnect with the utility as part of the job.
Many upgrades are completed in a day, though utility scheduling can affect the timeline. We give you a clear estimate after reviewing your service.
Yes. We pull the required permits and arrange inspection so your 200 amp panel upgrade is documented and code-compliant.
