## Generator Installation in Hillsborough, CA

A standby generator that runs your whole Hillsborough 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 Hillsborough

### 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 Hillsborough 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

★★★★★

Added outlets to three bedrooms and a weatherproof one out back. Cuts were small, patches were tidy, and everything got labeled at the panel.

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.

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.

## Generator Installation in Hillsborough — questions

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

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 Hillsborough?

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.

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

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.

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.
