MAIN 200AGenerator Installation in Millbrae, CA
A standby generator that runs your whole Millbrae 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 Millbrae
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 Millbrae 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.
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 Mateo County
Kitchen breaker kept popping whenever we ran the microwave and kettle. They put in a dedicated circuit instead of just telling us to use one appliance at a time.
Alicia G.Dedicated circuit · MillbraeWe needed a 200 amp panel before our EV charger install. They did the load calculation, pulled the permit, and had the whole thing done and inspected in a week.
Priya N.Panel upgrade · MillbraeStandby generator install. They sized it to what we actually use rather than the biggest unit, then walked me through the transfer switch and the exercise cycle.
Renee B.Generator · MillbraeGenerator Installation in Millbrae — questions
Do I need a permit to install a generator in Millbrae?
Yes, and often a gas permit too. We handle the electrical permit and inspection and coordinate with your gas contractor or plumber.
Can you install a battery instead of a generator in Millbrae?
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 Millbrae?
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.
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.
