Frequently Asked Questions

How much does sub-panel installation cost in Salem?

Most Salem-area sub-panels run $1,200–$3,500 depending on amperage, feeder length, trenching needs, and whether the source panel has spare breaker capacity. We provide a written estimate before any work.

Why does a sub-panel need 4 wires?

A sub-panel in a separate structure (or anywhere downstream of the main service) requires two hots, a neutral, and a separate equipment ground. The neutral and ground bars must be isolated at the sub-panel — bonding them again creates parallel ground paths and a shock hazard.

Can I add a sub-panel without upgrading my main panel?

Often yes — a load calculation tells us whether your existing 100A or 200A service has capacity for the sub-panel's expected load. If not, we quote the panel upgrade as part of the same project.

Do I need a permit?

Yes. New sub-panels and the feeders that supply them require an electrical permit through the Oregon BCD. We pull the permit and schedule the state inspector.
