MAIN 200AGenerator Installation in Sonora, CA
A standby generator that runs your whole Sonora 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.

Situations we see in Sonora
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.
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.
Not sure what size to buy
We meter and calculate rather than estimate. Most Sonora homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.
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.

Reviews from Tuolumne County
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.
Bill T.Troubleshooting · SonoraOur 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.
Ken A.Commercial repair · SonoraSix 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.
Tom R.Lighting installation · SonoraGenerator Installation in Sonora — questions
Can you install a battery instead of a generator in Sonora?
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 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.
Do I need a permit to install a generator in Sonora?
Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.
How much does a whole house generator cost in Sonora?
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.
