What are the 3 wires in Romex?

A 12-2 Romex will have a black(hot) and a white(neutral) wire as well as an unsheathed copper wire for ground. A 12-3 Romex will have a black(hot), red(hot), white(neutral), and bare copper. The red on a 12-3 is used for three-way light switches which are covered later.

Is it OK to splice Romex?

It must be noted that while it is possible to splice different types of Romex wire—12/2 to 12/3, for instance—you should never splice together wires of a different gauge. Wire gauge is determined by the amount of amperage the wire is expected to carry.

How do I extend my Romex?

Twist the black wire end around the existing black wire connection with the lineman’s pliers. Replace the wire nut and be certain no bare copper shows after the wire nut is in place.

Can you use crimp connectors on house wiring?

Terminals of a receptacle are permitted for use with certified field-installed crimped-on wire connectors or an assembly, if so identified by the manufacturer. A receptacle may also be provided with conductor leads with factory-installed crimped-on connectors.

Is it OK to use a junction box to extend wiring?

Mistake: No electrical box | Never connect wires outside of electrical boxes. Junction boxes (or a J box) protect the connections from accidental damage and contain sparks and heat from a loose connection or short circuit.

Are push connectors as good as wire nuts?

Wire nuts require proper wire stripping and splicing technique to ensure a good connection. On the other hand, push-in wire connectors are easier to install. Push-in wire connector types require no tools at all. Some other wire crimp connectors need a heat gun, a crimper, or both.
