What are the types of wire?

Types of Wire – A Thomas Buying Guide

• Fuse Wire. Fuse wire has a low resistance to allow normal current to pass safely through it, but if there is a short circuit that causes a higher voltage current to pass through it, the fuse wire can’t withstand the heat, so it melts and breaks the circuit.
• Magnet Wire.
• Stranded.
• Litz Wire.
• Tinsel Wire.
• Braided.
• Wire Harness.

Should I use 12 or 14 gauge wire?

As long as you don’t put too many lights on the light circuit, you can usually control that circuit with a 15-amp breaker, as well as wire it with a 14-gauge wire. On the other hand, an outlet circuit controlled by a 20-amp breaker requires a 12-gauge wire.

Can I use 14 gauge wire on a 20 amp breaker?

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.

Can I mix 12 and 14 gauge wire on a 15 amp circuit?

It is perfectly acceptable to use 12 gauge wire on a 15 amp circuit. It shouldn’t, many older homes were wired with 12 gauge throughout. Apart from that, it is actually explicitly allowed by code.

What is 14 gauge wire used for?

14-gauge are usedfor light fixtures, lamps, lighting circuits with 15 amps. 12-gauge are used in kitchen, bathroom, outdoor receptacles, and 120-volt air conditioners supporting 20 amps.
