Electrical Panel Upgrade Service
Upgrade your electrical panel from 100 to 200 amps — permits, utility coordination, and fixed pricing by licensed electricians with same-day availability.
Schedule Panel Upgrade
An electrical panel upgrade — also called a service upgrade or main panel replacement — increases the amperage capacity of your electrical service to support the demands of a modern home or business. Most properties built before 1990 were equipped with 100-amp service panels, which were adequate at the time but are increasingly insufficient for today's electrical loads. A household running multiple large appliances, an EV charger, a home office, and climate control systems can push a 100-amp panel to its limits. A panel upgrade replaces the existing main service panel, the meter base if required, and the main breaker with new equipment rated for the higher service level. The process requires a permit, utility coordination for the meter pull, and a final inspection — all of which our electricians handle as part of the quoted price.
Electrical Panel Upgrade — Everything You Need to Know
From the day-of process to signs you need one — here's what homeowners should know about panel upgrades before requesting service.
What a Panel Upgrade Involves
A panel upgrade begins with a load calculation to confirm the correct target amperage based on your current and planned electrical loads. Our electricians assess the existing panel, service entrance conductors, and meter base to identify every component that needs replacement alongside the main panel. On installation day, we coordinate with your utility provider to pull the meter and de-energize the service while the new panel is installed. The existing circuits are transferred to the new panel, connections are torqued to specification, and the panel is labeled clearly before the utility restores power. Most residential panel upgrades are completed in a single day.

Signs You Need a Panel Upgrade
The most common reason homeowners request a panel upgrade is adding a large new load — an EV charger, a hot tub, a home addition, or a second HVAC system. A load calculation often reveals that existing capacity, while technically adequate for current loads, leaves no safe headroom for the planned addition. Other indicators include a panel more than 25 years old, a Federal Pacific Stab-Lok or Zinsco panel regardless of age, breakers that trip repeatedly under normal household loads, and an insurance carrier that has flagged the existing panel as a condition of continued coverage.
- Planning to add an EV charger or hot tub
- Panel is more than 25 years old
- Federal Pacific, Zinsco, or split-bus panel
- Breakers trip under normal household loads
- Insurance carrier has flagged the panel
Benefits of a 200-Amp Panel Upgrade
A 200-amp panel provides sufficient capacity for a modern home's full electrical load with meaningful headroom for future additions. Beyond raw capacity, a new panel brings AFCI and GFCI breaker slots that older panels lack — reducing the risk of arc faults and ground faults that are leading causes of residential electrical fires. New panels use high-quality bus bars and connection hardware that eliminates the corrosion and loose connection issues common in aging equipment. Many homeowners find that a panel upgrade also resolves long-standing nuisance issues — breakers tripping unexpectedly, voltage fluctuations, and lights dimming under load.
- Supports EV chargers, additions, and modern loads
- AFCI and GFCI protection on all new circuits
- Eliminates corrosion and loose connection risk
- Resolves nuisance tripping and voltage fluctuations
- Improves home resale value and insurability

What Our Customers Say About Electrical Panel Upgrade
Here's what homeowners say about our electrical panel upgrade service. Every review is from a verified customer.
“We needed a 200-amp panel upgrade before our EV charger installation could happen. The electrician handled all the utility paperwork, filed the permit, and finished the job in one day. Passed inspection first try and we had our charger running the same week. Professional from start to finish and exactly on the quoted price.”
“Our 1965 Federal Pacific panel was flagged by our insurance company. Got three quotes and chose Local Trusted Electricians because they were the only ones who fully explained what the job involved before asking for a deposit. Clean work, all permits handled, the inspector passed it without any corrections.”
“Added a home addition and needed more panel capacity. The electrician performed a proper load calculation, recommended the right amperage, and upgraded us to 200 amps with full capacity for the addition circuits. Completed on schedule and exactly on the quoted price — no surprises whatsoever.”
