Shed Electrical
I just bought a house with a 16x12 shed in the back. I want to use it as a small woodshop. I would like at least 2 20amp circuits. It currently has a 4 wire 12ga feed from the house's main with a 20amp breaker. In the shed the red wire is not connected and not hot. In the basement, near where the wire goes out the house, there is a single gang box that says "To Shed". There is 12/2 Romex from the main breaker to that box. I assume the red wire in that box isn't connected to anything. So I have a 20amp breaker in the main. 12/2 Romex going to a junction box in the basement. There are 4 wires (red, black, white, green) buried in conduit (of unknown size ) from the house to the shed. In the shed the red line is wire nutted and not hot. The rest is going to the shed outlets and lights. I want to make a second 20 amp circuit out in the shed using the red wire. Do I replace the 20amp in the main breaker and add a 20amp two pole breaker then put in a sub panel in the shed? Seems like a lot to just add one more 20amp circuit that isn't completely independent? That won't solve my issue and I've read that may be unnecessary. I don't want to pull new wire because I don't know how big the underground conduit is, but I think that seems like the best solution (i.e. pull wire for a 40amp and then go to sub panel in shed with 2 20amp breakers - if the conduit size allows it) So knowing what I currently have and what I want to do, I am hoping to get some advice on how to go about it the easiest yet still correct way. Thanks. submitted by /u/dr_leo_spaceman_ [link] [comments]
