Electrical Panel Upgrade in Hidden Hills, CA

Panel upgrades are the job that unlocks everything else. In Hidden Hills and across Los Angeles County, most requests for EV charging, heat pumps or ADU power start with a service upgrade from 100 amps to 200, because there is simply nowhere left to land a new breaker.

Call (833) 652-8933 and describe what is happening. If it is a same-day job we will book it today, and if it needs a site visit to quote properly we will tell you that too.

Situations we see in Hidden Hills

Zinsco or Federal Pacific panel

These breakers have a documented history of failing to trip under fault. Replacement is the only real remedy, and it is one of our most common Hidden Hills jobs.

Panel is rusted or wet

Water in an enclosure corrodes bus stabs and creates high-resistance connections. Once rust reaches the bus, the panel is done.

No space left in the panel

Double-tapped breakers and tandem cheaters are a sign the panel is full. A 200 amp replacement gives you 40 or more spaces and room for the next ten years.

Adding an EV, heat pump or ADU

All of these need a load calculation. If existing demand plus the new load exceeds your service, the upgrade comes first.

Reviews from Los Angeles County

GFCI in the bathroom kept tripping. They found real leakage in an old fixture rather than just replacing the GFCI and calling it done.

Smart switches wouldn't work because there was no neutral. They pulled one, got everything on Lutron, and set up the scenes before leaving.

Six recessed lights in the living room and a dimmer that finally doesn't buzz. They laid the whole layout out on the ceiling with tape first, which I appreciated.

Electrical Panel Upgrade in Hidden Hills — questions

Do I really need 200 amps?

If you are adding EV charging, electric heat, a hot tub or an ADU, almost certainly. We run an actual load calculation rather than guessing, and if 100 amps genuinely still works we will tell you.

Do I need a permit for a panel upgrade in Hidden Hills?

Yes, service work is permitted and inspected. We pull the permit, schedule the inspection and meet the inspector so you don't have to.

How long will my power be off during the upgrade?

Plan on most of a working day. We coordinate the utility disconnect and reconnect so the outage lands in one block rather than spread over days.

Can you replace just the breakers instead of the whole panel?

Sometimes. On a sound modern panel, breaker replacement is fine. On a Zinsco, Federal Pacific or corroded enclosure, new breakers don't fix the bus, so the panel gets replaced.

How much does an electrical panel upgrade cost in Hidden Hills?

Cost tracks the service size, the condition of the service entrance and whether the meter has to move. A straight 100 to 200 amp swap sits well below a job that needs a new mast and underground feed. Call (833) 652-8933 and we will walk your panel and quote a flat number.
