How much does a sub-panel cost in Silverton, OR?

Do detached buildings need a separate grounding electrode?
Yes. Per NEC, a sub-panel at a detached structure requires its own grounding electrode system (typically two ground rods) and a 4-wire feeder with isolated neutral and ground. We install both.
Can I add a sub-panel without upgrading my main?
Often yes — we run a load calculation on your main panel first. If there's spare capacity and a breaker slot, a sub-panel is straightforward. If not, we'll quote the main upgrade alongside.
Do sub-panel installs need a permit in Oregon?
Yes. Oregon BCD requires an electrical permit and inspection for any new feeder or panel. We pull the permit and coordinate inspection.
