Last night I installed a new Whirlpool double electric wall oven in our 20-year-old house. Existing wiring was three-conductor: a black, white, and ground. The oven's wiring was: black, red, and a white wire connected to a ground wire, which can apparently be separated for 4-conductor wiring. I connected black to black, red (oven) to white (wall), and white/ground (oven) to ground (wall). That seems to work fine (so far). Did I screw up? Also, the cable coming into the cabinet enclosure is encased with the usual insulation (it is not in a flexible metal conduit, as the oven's wiring is). Is there a danger that the oven's heat will melt the insulation? (The junction box is inside the enclosure, above the oven). What about that paper wrapped around the ground inside the cable? Thanks in advance for any help. The wiring problem seems pretty simple on its face, but I don't want to create a safety hazard in my house.

We are building an addition, which includes a bathroom. When specifying our electrical needs, we indicated that we wanted controls for the fan/light/heater near the shower area. They would be on the wall opposite the shower stall, about three feet away from the shower doors. The builder says that the controls must be at least 5 ft. from the shower. I called our city's building codes dept. and was told that the five foot rule applies to tubs, jacuzzis, whirlpools, but that the NEC does not address the distance from showers. My builder is skeptical. I would like to confirm this since the city employee that I spoke with reviews plans but does not do the inspections. The builder is concerned that we may put it in based on the reviewer's input only to have it rejected during inspection. Can anyone confirm/deny this information or help me find the code that addresses this? We could accept putting these controls near the entry door but it would be much more convenient to have them near the shower. Thanks!
