What does 14 2 mean?

Here's a standard 14/2 strand of Romex electrical wire. Both 14/2 and 12/2 wire types have 3 wires wrapped in "sheathing". Yellow sheathing for the 12 gauge. White sheathing for the 14 gauge. Wire 1: The white wire.

Also, what is 14 3 wire used for?

143 cable (14 AWG–3 insulated conductors) allows you to have two separate hot conductors sharing the same neutral. Short answer, you use a 14-3 cable to wire a home light that is controlled by two different switches. Slightly longer answer. The 14 refers to the gauge, or thickness of the wire.

What is a 14 2 cable?

Copper cabling typically consists of 4 pairs of wire (8 total conductors) wrapped in a single jacket. For example, 14/2 indicates that there are two 14-gauge wires (a ground wire, if part of the cable, is not included in this number) within the cable.

Can you use 14 2 on a 20 amp circuit?

NEC 240.4(D)(3) states that 14 AWG must be protected at 15A. You can not use 14 AWG anywhere on a circuit that has a 20A breaker. If you are putting 15 amp receptacles on a 20 amp circuit with 12 gauge wire, then you MUST use the screw terminals, not the back stab terminals. Just use the side terminals.
