Keep in mind that there is a difference between 12-4 and 12-2-2. 12-4 contains black, red, white and blue and is intended for 3-phase application, while 12-2-2 contains red, black, white and white/red stripe. You need to use 12-2-2, as the neutral must be coded white. ericm215.
In*nonmetallic sheathed cable* (NM) used for residential and commercial*wiring, the outer sheath color indicates the wire gauge or size and*amperage rating*of the wire within. Before about 2001, most NM cable had a white outer jacket, but beginning in 2001, most NM-B cable is jacketed with a vinyl out insulation that is colored to identify it ...
My house was built in 1977 and most of the wiring for outlets and light switches only have a black and a white wire without a ground wire. The wiring up in the attic has a black sheath on it and says south wire 12/2 600v. I'm trying to get power from somewhere in dining room to power a ceiling fan but nothing in there has a ground wire.
I am getting ready to wire up my can lights and I was wondering I have the switch already hot with 12/2 wire up to it. Can I run 14/2 from that point on up to each can? 14/2 is just so much easier to use and feed into the boxes on the can lights? Just wondering as I plan on hooking up the electrical within the next few days.
I will be running a new 20 amp wire in my crawl space from my breaker box to an outside wall box. Do I need to use outdoor wire, or since it's under my house, can I use indoor wire.
Question: Is using 12/2 wire, ok on 15amp breaker/outlets/switches? i will NOT use any 20amp outlets or breakers, everything will remain 15amp.. i know the proper is 14/2, i just got a huge discount on some overstock 12/2 ro-mex wire.. [ $100 for 500feet i can almost re-do my entire house with this, lol] i know i've seen this question asked several times before, but i just wanted to make sure ...
Joe, I am not an electrician but from my understanding you can use 12/3 and cap off the red wire at both ends. If in the future you need a 240 volts appliance installed you can use this 12/3 wire and use the red. I guess the short answer is YES and cap off the reds. 12 gauge for 20 amps is correct.
Wire size question, 12/2 or 14/2? The house was built in 1985 and I think all of the wiring is 12/2. There are 15 amp and 20 amp circuits. There is 12/2 wire on a 15 amp circuit, that's what makes me think the whole house is 12/2. Would there be any issue installing a new bath vent fan where there was not one before with it's own switch, using ...
AllanJ talks about 3 ground wires?? but I only have two grounds being it's 12/2 wire.
I have two other outlets that are already wired with 14/2 wire. I would like to put the outlets on the same circuit and wondering if it is okay to mix the 14/2 and 12/2 wires on the same circuit IF I swap out the breaker to a 15 AMP.
