## Situations we see in El Monte

### 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 El Monte jobs.

### 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.

### 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.

### 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

★★★★★

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.

Breaker tripped Sunday night and I got a call back in about ten minutes. Tech found a bad connection in a junction box behind the closet, fixed it that night, and the price was what he said on the phone.

Flickering through the whole house turned out to be a loose neutral at the service. They found it in under an hour when two other companies had shrugged.

## Electrical Panel Upgrade in El Monte — questions

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 El Monte?

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.

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.

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.

Do I need a permit for a panel upgrade in El Monte?

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