I'm planning on building a 4' deep x approximately 44' wide mezzanine on the back wall of my 30 x 50 shop.
The back will set directly on the framed wall as you see partially framed, but the front will have to be supported by posts every so often. I plan on having a 30"d x 36" tall workbench...
Wire was delivered Saturday via Fedex, and I managed to get it in conduit and mostly buried over the weekend..
What size breaker should I put in the main panel to service the (2) 15A breakers in the shed?
30A or 40A?
Just black, but I will label accordingly.
Funny, but both the XHHW-2 and the URD show the jacket as crosslinked polyethylene.. But I guess it's not all created equal.
It's hard to imagine what the difference would be..
If I used a jumper from one lug to another, the lug wouldn't actually be carrying the current of both legs, just used to physically bond the incoming and the jumper to the next leg.. but hey, I'm not an electrician, nor to I pretend to be.
It's a 12 x 18 building, so we had planned on running an electric heater on the same circuit that the window ac is on.. basically that circuit will be dedicated to hvac..
but you are right, for another $26 I can run another #6 AL and be done with it, hardly even worth thinking about.
Thanks for all the input. I'm still weighing options..
Wireandcableyourway.com has #6 XHHW for $.20 per ft, so that would make a 120v run $.60 per ft. VS $1.11 for 10-3 UF.
I'm a noob but it doesn't make sense to me either.. ordinarily you would have multiple breakers on a single leg.
If I had a panel with 8 spaces, 4 of those would be on one leg, and the other 4 on the other leg.
I called all my local suppliers this morning and none carry #6 XHHW in aluminum.
I...
Thanks, I suspected so..
This is the panel:

My original intention was just to have a single 120v leg out there as there will be absolutely no use for 240v..
I basically was just going for overkill and as little voltage drop as possible and I wanted to make sure I had the capacity to run the two 15a circuits.
The run is about 120ft...
