I am in the process of putting down some outdoor conduit at one of my properties. I am replacing some old UF wire that wasn't buried properly (or came up over the years) and has shorted.
I chose to go with metal conduit, because from what I've read, the NEC only requires a min. depth of 6 inches.
The conduit will hold the 40 amp 'line' for my A/C unit; if possible I would like to have it also hold another 20 amp 'line' for an outdoor outlet.
My questions are:
- What size conduit should I use? (I was thinking 3/4")
- Can I snake all wires for the AC and outlet in one conduit (2 conductor 1 ground for ac [8awg] / 1 conductor 1 neutral 1 ground for outlet [12awg]) - not sure the fill on this size
- When i stub up, I need to wrap around the foundation a little bit; any issue going above a hose spigot?
- Am I crazy for using rigid metal conduit? A lot of people I know say just go 'as deep as I can' and use PVC. But that's against code and even though this won't be inspected I try to stick to code as much as possible.
Thank you for the help
