So I have an #8 THHN/THWN multi conductor cable labeled in accordance with ICEA method 4. There are 3 insulated #8 conductors all colored black and with printed labeling to identify the conductor number ("1 ONE", "2 TWO", "3 THREE"). From my reading of the ICEA docs, this is method 4 (basically, the conductors are numbered, not colored). There is also an uninsulated (bare) #10 ground, so a total of 4 conductors. My question is, is there a convention for which 2 conductors should be hot and which should be neutral? And do I have to put colored tape on what would be the white and red at each end of the run? It's only a 10ft run, from my electrical panel to a Reliant Controls generator power inlet box thingy. The ICEA method 1 table E-2, and method 3 both have conductor 1=black, 2=white, 3=red, so my guess would be to follow that, but nowhere is it stated explicitly what the convention is for method 4. See: [URL]http://www.houwire.com/pdf/color_codes.pdf[/URL] No, I'm not back feeding; I have an interlock kit installed on the electrical panel.

Hello my first time here. I just move into a new house and I was shock on what I saw with the wiring through out the house. While I am not an electrician, I do know a little about wiring since I was in the AC/heating business. But it's been a while since I did some wring and I am sure many of the codes have change over the years. I appreciate any tips and help. The house is wired with old and new BX cables. Many of the 14/2 were mix with 12/2 wiring. I also notice that many of the 12/2 wiring were on 15 amp breakers. I removed most of old BX cables and replace them with romex 12/2 and replace the breakers with 20 amp. The 14/2 wiring is on 15 amp breakers. Please tell me if I did this correctly, a dedicated line to the sump pump, Stove(with range hood), Refrigerator (12/2 20a), Gas furnace (14/2 15a), Washing machine(12/2 20a) and Dryer (10/3 DP 30a). I'm going to run a dedicated 12/2 GFCI line to the bath room. There is already a ceiling fan light with a switch, but no outlets. I though running another line to the bathroom would be the best thing to do. I am also a firm believer running lights and receptacles on their own separate lines. However, will it be okay to run one 100w light off a 12/2 line with 3 receptacles in the room? This is a small computer room with a wireless router, all in one printer and cable modem. BTW is it okay to use 15a receptacles on a 20a line? Someone told me I should be using 20a receptacles. I already replace all the old outlets with 15a receptacles on the 20a lines. I have more questions later, but I would like to finish the downstairs first. Thanks.
