I'm wiring my shed. There is a sub panel out back with a 20A breaker that supplies power to my pool light. I tapped that line to run the power to my shed because it's already ran about 3/4 of the distance. I used 12 gauge wire from the junction box near the pool to the shed, but 14 gauge wire in the shed. I didn't realize it was a 20A breaker until about half the wiring in the shed was done.
Rather than redo what I've already done in the shed, I thought about just swapping out the 20A breaker for a 15A breaker. The load will be:
- The pool light (2.5 amps)
- Five lights on the shed (3 outside, 2 inside)
- Four outlets
The alternative would be to rewire the shed and keep the 20A breaker, but I don't want to do that since I really don't need 20A of power out there.
