Generator Installation pricing in San Marcos, CA

Whole house generator installation cost in San Marcos depends on generator size, fuel type, distance from the gas meter and electrical panel, and local permit requirements. A portable generator inlet with an interlock is the budget option; an automatic standby system costs more and does far more. We measure your loads and quote both ways if you want to compare.

San Marcos generator installation FAQs

Can I just plug a portable generator into an outlet?

No. Backfeeding through an outlet is dangerous for you and for utility crews. A transfer switch or interlock with a proper inlet is the safe, legal way to connect a portable generator.

Do generators need permits?

Standby generators need electrical and usually plumbing or mechanical permits, plus placement that meets clearance rules. We handle the applications and inspections.

Generator or battery backup?

Generators run as long as they have fuel; batteries are silent and pair well with solar. Compare the two on our solar and battery backup page, and consider whole house surge protection either way.

What size generator do I need?

It depends on what you want to run. We add up starting and running loads for your essentials or your whole property in San Marcos, then recommend the smallest unit that covers them comfortably.

In customers' words

After two long outages we had a standby generator put in. They sized it properly instead of pushing the biggest unit, and showed us how the transfer switch works.

Rob H.Standby generator

They wired our kitchen remodel from rough-in to final. Island outlets, under-cabinet lights and all the appliance circuits. Our contractor asked for their number.

Paul D.Kitchen remodel wiring

After a surge took out our garage door opener and a TV, they installed a whole house protector at the panel. Quick job, clear price, no upsell.
