I'm not remotely understanding what your talking aboutbk406 said:
BK: Thanks for the info on PVC, good to know the differences. But, the OP described having 1/2" EMT, so I wanted the OP to understand that he could only safely run 4 x 14 gauge wires. I'm really not trying to make things confusing, only to emphasize that new conduit will be needed. Regardless of what size PVC conduit he runs, he's going to need to dig a new trench and run new conduit; 1/2" EMT is not going to work for the loads he describes. The OP also asked if above ground conduit would be okay. I guess this would be a matter for his local building code, since there are apparently some types of conduit that can be run above ground.bk406 said:Craig,
An Easytouch automation panel IS a subpanel with 8 breaker slots.
Bottom line is the OP can run 3 conductors using #3 copper, and one ground using #4 in 1 inch conduit (PVC) attached to the house. (Craig, your using the wrong table for conduit fill. For schedule 40 PVC, which is all he needs, the proper table is C10, not C8. C8 is for EMT).
He can run #3 copper and #4 ground with a 100 amp breaker in his main in 1" PVC and be completely code compliant. I like to run as much power as I can. You never know what you might need in the future. It's just as easy to run a little bigger wire up front.
Let's don't go all TFP difficult (like I know we can, LOL). Its a pretty straightforward project.
He doesnt have to dig. He can run the PVC above ground (or EMT for that matter) as along as he attaches it to a structure. NEC says you can. I've never seen a JHA that wouldnt let you do it. Only restriction is some JHA might require schedule 80 outside, but most will let you use schedule 40 if in an area not subject to physical damage.CraigMW said:Regardless of what size PVC conduit he runs, he's going to need to dig a new trench and run new conduit;.
bk406 said:. In either case, the 1/2" conduit you have is not even close to being adequate. The NEC dictates conduit fill requirements.
Too true!bk406 said:I only said lets dont make it complictaed because i've beeen on TFP long enough to know that some of us can go on and on, for pages and pick over the last bit of minutia, and confuse an OP beyond belief when the answer is really straightforward
