## Generator Installation in Antioch, CA

A standby generator that runs your whole Antioch house is a different machine from one that keeps the fridge, the furnace and a few lights alive. Rupert Electrical Solutions starts with a load study so you buy the right size instead of the one on the showroom floor.

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 Antioch

### Whole house or essential circuits

A critical-load subpanel is far cheaper than whole-house coverage and keeps heat, refrigeration and internet running. We price both.

### Existing generator won't start on outage

Usually the transfer switch, the battery or the exercise routine, not the engine. We diagnose the switching first.

### Not sure what size to buy

We meter and calculate rather than estimate. Most Antioch homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.

### Extension cords through a window

Common and genuinely dangerous. An inlet box and interlock costs a fraction of a standby unit and ends the practice.

## Reviews from Contra Costa County

★★★★★

Bought a 1948 house with cloth wiring. They phased the rewire so we always had power in half the house, and gave us paperwork our insurer accepted.

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.

Our restaurant lost the walk-in circuit on a Friday. They came out after close, traced it to a failed feeder lug, and we opened Saturday on time.

## Generator Installation in Antioch — questions

Can you install a battery instead of a generator in Antioch?

Yes. Battery backup runs silent, needs no fuel and pairs with solar, but has a fixed energy budget. For multi-day PSPS events a generator still wins on runtime.

How much does a whole house generator cost in Antioch?

The unit is roughly half the project. The rest is the transfer switch, pad, gas line, electrical and permit. Sizing drives everything, so call (833) 652-8933 and we will run a load study before quoting.

Will the generator start automatically when the power goes out?

With an automatic transfer switch, yes, typically within 10 to 30 seconds. With a manual switch or interlock you start it and flip the switch yourself, which is a cheaper install.

Do I need a permit to install a generator in Antioch?

Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.

How often does a standby generator need service?

An annual service plus the weekly self-exercise cycle. The exercise routine matters more than owners expect, because it is what catches a dead battery before an outage does.
