Subpanel Installation Instant Price

Answer a few quick questions and see your estimated price for a new subpanel right away. No scheduling or payment needed.

Step 1 of 9

What size subpanel do you need?

Not sure? 100A fits most garages and ADUs. We’ll confirm the right size with a load check.

Where will the subpanel go?
How far is the subpanel from your main panel?

Measure the path the feeder would take. The first 25 ft are included.

Will the feeder need to run underground?

Underground runs add $50 per foot of trench.

About how many feet of that run is underground?

Only the part that goes underground. It can’t be longer than the total distance. Trenching price depends on soil conditions and is confirmed at the site visit.

What size is your main panel?

Read the number on the main breaker (usually the largest breaker, at the top).

Do you want a permit pulled?
