I want to add some circuits for my workshop equipment but my main panel is maxed out. I was thinking of adding a sub about 3 foot away from it to connect the new circuits. In order to supply the sub I will have to move two breakers from the main and add them to the sub to create space for the breaker feeding the sub. In moving the two ciruits can I just move the 2 lives and leave the nuetral and grounds alone in the main? Thanks

Hey all, The workshop build is coming along nicely, and we're planning for the electric service. The house itself is served by a panel with "Arrow Hart Murray" on the cover, it's an integrated service entrance/meter/breaker panel unit. The breakers are arranged in two horizontal rows, rather than two vertical rows. There's an unused position in the top row next to a single-pole breaker that's unused, and the bottom row has a couple of positions that were previously in use for a pool that is now no longer present. I'm assuming that a pair of hot wires, a neutral wire, and a ground wire will need to be pulled through the in-ground conduit, and that the two hots and the neutral will need to be sized the same, and that the ground can be sized a little smaller. I'm currently planning on 2AWG THWN for the hots and neutral, and 8AWG for the ground... The new building foundation does have ground. I assume that even with this, I need to bond the grounds together and to the sub panel itself, but the neutral needs to be non-bonded, letting that occur in the main panel only... I'm sizing this for 100A total. The workshop will have an air compressor, a vehicle lift, an evap cooler, a couple of circuits of lights, and at least two, possibly four electrical circuits for outlets.
