Sub Panel Installation FAQs – San Marcos

What size sub panel do I need?

It depends on the loads you plan to run. We calculate it during the estimate.

Can you run power to a detached building?

Yes, via underground feeder or overhead conduit as the site allows.

Does an ADU need its own panel?

Most do. A dedicated sub panel also simplifies future metering.

Do you handle permits in San Marcos?

Yes. For permitted work in San Marcos we pull the permit, schedule the inspection and meet the inspector.
