Older electrical panels often lack the capacity for today's appliances, EV chargers, and home electronics. Our licensed electricians assess your current setup and install a panel sized for your actual load, reducing tripped breakers and easing strain on your wiring throughout the Signal Hill area.

We keep panel upgrades straightforward, from the first assessment to the final inspection.
An electrician examines your current panel, wiring condition, and household or business power needs to determine the right amperage for your upgrade.
We outline the recommended panel size, breaker layout, and any permit requirements before scheduling the work.
The old panel is safely disconnected and replaced, with new breakers installed and every circuit properly labeled.
We test the new panel under load, confirm proper grounding, and coordinate any required inspection before wrapping up.
Get clear answers about service panel upgrade, preparation, timing, maintenance, and what to expect before requesting an estimate.
Q1
Common signs include breakers that trip frequently, flickering lights, a panel with fuses instead of breakers, or plans to add an EV charger or hot tub. An electrician can confirm whether your current panel is undersized.
Q2
Most residential panel upgrades take one full day, though the exact time depends on panel size, wiring condition, and whether utility coordination is needed for the disconnection.
Q3
Yes, power to the panel is shut off during installation for safety. We schedule the work to keep the outage window as short as possible.
Q4
Yes, panel upgrades typically require a permit and inspection. We handle the paperwork and coordinate the inspection as part of the project.
Q5
Most homes today are upgraded to 200 amp service, though this depends on square footage, appliances, and future additions like EV chargers or generators. We calculate your load before recommending a size.
Q6
Yes, replacing a fuse box with a modern breaker panel is one of the most common upgrades we perform. It improves safety and gives you more capacity for current electrical demands.
Q7
Yes, we perform panel upgrades throughout Long Beach, Torrance, Huntington Beach, Lakewood, Downey, Pasadena, and Anaheim in addition to Signal Hill.
