To keep myself busy (as if I'm not busy enough ) my parents and I are building a house in Wisconsin (retirement house for my parents, although it's probalby going to be just a vacation house). The house is pretty much done on the outside, so now I'm working on the plumbing and electrical. I've done a lot of electrical work so far, but I've never ran a circuit for an electrical range/stove and dryer. You just don't find any in Chicago. It's all gas. I know I have to run a 4 wire circuit to each, but what size? I went to HD yesterday and looked at some ranges, and according to the instructions they all said run a 40 or 50A circuit. Should I run a 50A circuit? I don' t want to buy the stove just to run the circuit. Also, what kind of box/outlet should I use? I want a flush mounted outlet, and I assume I'll need a double wide box to accomodate that (the wiring is NM with blue plastic boxes). I assume the same will apply to the dryer circuit also.
On a related note (being that this is the first time I've ever used NM wiring, I was all EMT and BX before ) I need finish the circuit for the well pump/tank (right now it's just running on the floor). Can I use a 1/2" EMT down to about 2' off the floor, then use a EMT to BX fitting from there to the pressure switch? I know I need to protect the cable, and I want the wiring to be on the outside of the wall. I know I could use a junction box, but I think it looks nicer without a box. I want to run 1 single 12-2 NM cable through to make the actual electrical connections. Will this be ok?
