adding new romex that has red black and white other romex has black white and green?

Question

how do I hook them to the fuse box don't want to confuse any boby should I wrap the red with black tape I know it is a differnt guage but I have plenty of this and no 14-2 like w to w b to b r to green or what

sorry folks sounds like a lot of electricians out there----- no bare or copper wire on it just a very small alum. like the shield or outer cable that why I don't know what to use as ground it for a 110 power pole that has black -white -green to tie into (sorry )

Answer 1

This is the convention: Black is hot, red is hot, white is neutral (ground), green is ground (ground), and naked copper is ground (ground). Never hook green to red! That would likely cause an explosion. If some of your Romex is black, white, green and some is black, red, white and naked copper, then use the black to black, white to white, and green to naked copper. Do not use the red wire at all, or if you want to use it, use it as a second black wire if you have a need for this. As someone said earlier, the red wire is used either to hook up 220V service or else to hook up multiple light switches to operate a single light from multiple locations. Otherwise it is not needed.

Your problem is not a National Code issue, it is local. (I won't go into the whole union/Democrat construction control thing for Chicagoland...) Running on the ceiling is an option of you have room for the conduit radius between the structural ceiling and a lower framed ceiling. I believe EMT is acceptable vs. RMC. You're likely going to have to cut 3' pieces and use a lot of couplings, there are some trade methods that could eliminate a few couplings, but if you are not familiar with these ways it will take more time to learn that to just cut it. Not really any simple way, you can leave some studs out during framing, drill holes for straight pipe in studs adjacent to where the pipe needs to be, then slide the pipe into the studs after install. But I am an electrician, and I would be cutting a bunch of pieces trying to use the joist space and dropping vertical whenever I could. One unfortunate effect of this law is spaces get wired to the minimum requirement, and this encourages the overuse of extension cords.

Answer 4

Never use a red wire for ground! Black wires and red wires are always hot. White wires are always neutral. Green wires and bare copper wires are always ground.

If your romex has red, black and white wires, it should also have a bare copper wire for ground. If it uses 14 gauge wire, it is called "14-3" romex, with the 3 denoting three conductors, not counting the ground wire.

I have not heard of romex with a green wire, since the jacket for the romex provides adequate insulation for the ground wire. However, when individual THHN wires are pulled through a conduit, a green wire is always used for ground.

If you don't need the red wire, don't cut it off, but instead put a wire nut on it and fold it back out of the way. This can be a spare wire for some future use.

Answer 5

The romex with a red wire in it has two purposes. One is to supply 230v to an outlet that need it, i.e. electric clothes driers, electric stoves and central air conditioner. The other purpose is to wire up two way light switches, like one down stairs and one up stairs so that either switch can turn the light on or off from either side. If you look inside your breaker box, there are 3 bus bars. 115v-A, neutral and 115v-B. Most outlets in the house is the 115v so the romex is used with black, white, and usually bare ground wire. Black is hot (115v-A), white is neutral and green or bare wire is ground. However when a 230v outlet is required, romex with red, black, white (optional) and green or bare ground wire. Red wire is connected to the 115v-B bus bar so the voltage you get between black and red wire is 230v. This standard color coding tells the electrician later how the romex is wired. This color coded connection is strictly forced by the electrical code and must not be deviated. If color coded wiring is not followed, it can cause electrical shock or fire.

Answer 6

I don't have the foggiest what you are trying to do. i would not use 14 gauge wire for anything concerning AC current. if you insist, i suppose you could use the red as a ground, but mark it at all connections with green tape.

If you are doing wiring in Europe or elsewhere where they use 220 V rather than 110 we use here in the states, you are going to have problems with it, and it will be a fire hazard. the smallest i ever use is 12 gauge wire, mostly i like ten or bigger. Stranded is better than solid, it carries more current for it's size, and stays cooler.

Answer 7

what are you gonna do? your new romex is 14-3 so if you dont need the red one put wirenuts on the ends also..black to black..white to white...green to bare copper wire on the 14-2

Answer 8

You have plenty of what and no 14-2, are you familiar with wire sizes and amps and what you're powering up?

Answer 9

Go out and buy the correct wire to do the job or hire an electrician. No sense taking chances.

Answer 10

Apperantly you are not using the standard 12-3 romex sounds more like a cable used for something like a welding unit or something like that. The green wire is an earth ground connection that is not normally used in home wiring and this wire that you have probably won't wont pass code either. Do yourself a favor and get the right wire. Hope this helps.
