Alright, I know this has been covered to death, but it seems everyone's situation is a little different (I searched...I swear).
I'd really like to power up my new shop and I figured now would be a decent time to buy most of the parts since I have one of those HD 10% off coupons.
The specifics:
Small 12'X12' detached "shed"
The feeder run will be something like 90' long
I figured on the following circuits:
(1) 15-20A lighting
(2) 20A general power (BT, CMS, DP and misc stuff)
(1) 20A Dedicated DC/Compressor
(1) Maybe future A/C - not sure, haven't worked in there yet
The Questions:
1. I've read the debates on 50-60A sub-panels vs. 100A. The argument is...the higher rating doesn't cost much more. BUT...do I really need 100A? The feeder is going to cost more, the conduit will be bigger and the wire will be harder to work with.
2. I'm confused with how many wires I need to feed the panel with. I read both 3 and 4... the difference being 2 hots. What gives?
3. What gauge feeder wires do I need for 60A? How about 100A?
4. The tricky question: My yard drops pretty good on the side, so-much-so I have a walk-out basement. I want the feeder conduit to come out of the side of my garage (where the panel is), go underground to the corner of my house, and come back out of the ground as the grade drops away. I then want that exposed conduit to run along the side of my house (pretty much even with the first floor), under the deck and into the shed (which is under the deck). Is it legal to have a conduit with a 50-100A load within hand's reach?
Thanks for reading...and commenting.
