Frequently Asked Questions
How much does it cost to wire a detached shop in Salem?
Most Salem-area detached shop or garage sub-panels run $2,800–$6,500 installed. Trench length, panel size (60A vs 100A vs 200A), and how many 240V circuits you need are the biggest cost drivers.
What size sub-panel do I need for a home shop?
A typical hobby shop with a welder, compressor, and LED lighting is well-served by a 100A sub-panel. Heavier loads (CNC, large welder, EV charger, heat pump) often justify 200A. We run a load calc as part of the estimate.
Do I need a permit for shop or garage wiring in Salem?
Yes. Oregon BCD requires an electrical permit and inspection for new feeders, sub-panels, and dedicated 240V circuits. We pull the permit and coordinate the inspection.
Can you trench under a driveway for shop power?
Yes. We coordinate trenching, conduit, and concrete saw-cut/restoration as needed, or run aerial service where appropriate.
Can you add a 240V welder outlet to my existing garage?
Yes — if your panel has capacity. We run a load calc, install a properly sized breaker, and add a code-compliant NEMA 6-50 or 14-50 outlet.
