How do I wire electricity to my garage?
Build Your Garage Sub Panel
Dig an 18-inch deep trench for the outdoor electrical wire, which you will run from the main panel box to the garage sub panel. Use 1 1/4-inch PVC conduit for a 100-amp sub panel or 1-inch PVC conduit if the sub panel is 50 amps or less. Run the conduit from the garage to the main panel box.
Is conduit required for garage wiring?
In general, conduit is required where the cable is exposed to possible damage or exposed to the elements. A sheathed cable protected behind drywall generally does not need conduit. If there is open framing (common with detached garages, uncommon with attached garages) the local electrical code will vary.
Can electrical wire be exposed in garage?
In a house or a finished garage, electrical cable is protected from damage by permanent wallcoverings like drywall, plaster or even wood, but that’s not the case in an unfinished garage. The key to safe, code-compliant exposed wiring is to use the framing members to protect and support the wires.
How many electrical circuits can you have in a garage?

Is 30 amps enough for a garage?
Depends on what you’re doing out there. I’ve had a 30 amp subpanel in my garage for a decade and it works fine for me, but I don’t have any large loads like a welder or air compressor. That said, if I were to do it over again I’d go larger just in case.

100 AMP service is fine, but use a larger panel with lots of circuits.
