Sub Panel Installation FAQs – Costa Mesa

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.
