Well, I bought over 800' of 3/4 conduit and 200' of 3/4 PVC yday and have started trenching/laying. My goal is to start outwards and work my way to the house. I think i've gotten some code clarification here before and hope that's ok to ask again:
Basics: (4) 20A circuits coming off GFI breakers to a panel/project box with contactors whose coils are controlled by 24VAC off the elk - romex to the contactors. Outbound via single runs of 10AWG stranded/color coded (red/black/white) THWN (went 10AWG because of the voltage drop over 100'+ distances and stranded cause that's all Lowes has in 10AWG and easier to pull. Green 12 AWG solid for grouns. I will keep all my runs at 4 90 degree bends or less so as not to exceed the 360 degree rule i was reading from NEC. I will basically run two crcuits to each 2 gang box (hense the red/black) and share the neutral/ground.
Questions
1) i read somewhere in an online electrical forum that plastic conduit is a no/no once you're indoors. Is this true and if so, true for exposed items / high voltage only/etc? I've used conduit to get low voltage wire between stories to get from my LV panels up into the attic, etc before. Was hoping just to bring the wire into block walls via plastic LBs and then plastic up the walls and into the attic for these circuits too...
2) Related to #1, I am pretty sure uncovered THWN in the attic is a no no, so again, was hoping not to transition to metal up there. If i have to, where is the best place/approach to do it? I was thinking maybe junction boxes in the attic and taking romex (no conduit) from contactors to there ad then transitioning to the single strands from that point on.
3) from my reading, once i leave the house, romex is a no-no even in conduit... so if i transition outside, i guess i'm forced to use UF/THWN for an inline box right on the exterior wall (even if it's on it's own circuit)?
4) i also read that solid is ideal for terminating outlets. Will i have problems with the stranded? Or can/short i buy a short amounts of 12AWG solid THWN and wire nut it to the feeds to make the connections easier?
5) Is there a problem putting an outlet and hose bib of opposite ends of a 4x4 post coming out of the ground and if so what's the spacing requirement?
6) likewise, any distance requirements on the wall of the house. I've got a hose bib mounted on the narrow corner wall next to my garage door and would like to put outlets close by. I think from simple reasoning on my part, i probably would prefer to put them around the corner, but is that enough?
thx in advance
