How far can I run 12 2 wire on a 20 amp breaker?

That number drops to 50 feet if you run 12 gauge wire on a 20 amp circuit.

Can I mix 12 and 14-gauge wire on a 20 amp circuit?

Generally speaking, #12 is good for 20A and #14 is only good for 15A. So if you have a 15A circuit, you could mix them with no problem. However if you have a 20A circuit, you can’t use #14 at all.

What is the minimum wire size that can be connected to a 20 amp breaker?

Building codes based on the National Electrical Code prohibit the use of 14-gauge wire anywhere on a 20-amp circuit. All wiring in such circuits must be 12-gauge or larger.

Can you use 10-gauge wire on a 20 amp receptacle?

Yes, you can use 10 AWG copper conductors with a 20 ampere breaker. The smallest size conductors you could use with a 20 ampere breaker, are 12 AWG copper conductors. There’s no problem using larger conductors, other than cost to you, and difficulties associated with working with thicker conductors.

What electrical cable can I use outside?

(Type UF cable is the most commonly used nonmetallic cable for residential outdoor wiring runs.) UF cable can be direct buried (without conduit) with a minimum of 24 inches of cover.

What is the proper breaker and wire gauge?

For circuit breakers up to 15 amps, use 14 gauge wire or larger. For a 20 amp breaker, use 12 gauge wire or larger. For up to a 30 amp breaker, use 10 gauge wire or larger. These are the most common sizes for household use. Wire is manufactured to a specific group of sizes that are designated by numbers known as gauges.

What is wire size for a 20amp breaker?

The rule of thumb that techs will usually go by is that for a 30 amp circuit breaker, 10-gauge wire is the right size to go with. For a 40 amp you need a 8-gauge wire size and for a 20 amp, you will need a 12-gauge wire size.

What gauge wire should I use for my amp?

20 for a copper wire with an ambient temperature rating of 60 ℃ or 140 ℉,which is the most common connection

What gauge wire for home wiring?

Wires – Wires are copper or tinned copper, the most common conductor in home wiring with minimum resistance that come for reasonable cost. Wires are usually grouped by gauge number ranging from 00-40. Smaller the number thicker is the wire. For residential/ home, wire gauge ranging from 10 to 20 are used.
