MAIN 200AGenerator Installation in San Bernardino, CA
A standby generator that runs your whole San Bernardino 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 San Bernardino
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.
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 San Bernardino homes land between 14kW and 26kW depending on AC, well pumps and electric ranges.
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.

Reviews from San Bernardino County
Hot tub circuit and disconnect. Permit, inspection, everything. Showed up when they said and cleaned up after.
Owen H.Hot tub wiring · San BernardinoFlickering 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 · San BernardinoSix 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 · San BernardinoGenerator Installation in San Bernardino — questions
Can you install a battery instead of a generator in San Bernardino?
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.
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 San Bernardino?
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 San Bernardino?
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.
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.
