I've got a small Square D breaker box I am wiring for service to a shed that I am having problems wiring.
The box will be supplied by 10/2 UF with ground coming from a 30 amp breaker in my home's breaker box. I have 10/2 NM wire with ground that is coming into the box. The box will power three circuits: one circuit with 5 recepticles, one circuit with two recepticles (for a small A/C and dorm fridge) and one circuit with some lights. Each circuit is run from a 20 amp breaker in the box using 12/2 with ground wire. The problem is that I'm not exactly sure how to wire-up the box. I have a diagram of the box here:
Then I would pigtail the white and ground for each circuit together and connect them to one of the four connectors on the center part of the bar to the right of the breakers. Then I would connect the white and ground wires coming from the feeder to each of the bigger posts on the top and bottom of the bar to the right of the breakers.
For the pigtail going to the circuit breakers I would use a red wire nut and 10 gauge black wire. For the pigtails going to the neutral and ground posts I would use a red wire nut and 12 gauge white wire.
Here's what I think it would look like:
I have a qualified electrician checking my work, but he isn't available for a few days and I don't want to make a mess. The circuit will not be energized until the electrician checks it out and I have passed county inspections.
Thanks!
