“Flickering lights turned out to be a loose connection in the panel. They found it with a thermal camera and tightened everything. No more flicker.”
— Diane C., Highland, CA

Sub Panel Installation FAQs – Highland

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 Highland?

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