Do I need to rewire my shop?

208cheezhead · May 25, 2023

Hello! My shop is currently on a single 15 amp circuit. Is like to upgrade it at the main home panel to a 30 amp. Do I just need to run 10 gauge wire from the main panel to the shop subpanel and then add a second 15 amp circuit on the subpanel? The shop is currently wired with 12 gauge wire. I wanted to make sure that is fine for this application.

Yes you would need to install a 30 breaker and pull #10 wire times 4 to your sub panel and then install a 15 amp breaker for the existing load in your building.
