What wire do I use for a 20 amp outlet?
12-gauge
A 20-amp circuit, protected by a 20-amp breaker or fuse, must be served by 12-gauge or 10-gauge wire.
Can I use 14 gauge wire on a 20 amp outlet?
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.
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.
Can you run 12 and 14 gauge wire together?
Anyway, the first subject is a bit touchy because it makes it difficult to perform an inspection when all of the wires coming into the panel are 12 but many of the circuits have 14 in them too. There is nothing against code mixing wire size for these circuits as long as the OCPD matches the smallest wire.
How far can you run 10 gauge wire on a 20 amp circuit?
How Far Can You Run 10 Gauge Wire? You can run a 10 gauge wire up to 85 feet on a 20 amp circuit. If you opt to use this type of wire on a 15 amp circuit, it can run up to 115 feet. After these distances, the circuit will go over the recommended 3% voltage drop.
Can I use 8 gauge wire on a 20 amp circuit?
“Twelve-gauge wire is good for 20 amps, 10-gauge wire is good for 30 amps, 8-gauge is good for 40 amps, and 6-gauge is good for 55 amps,” and “The circuit breaker or fuse is always sized to protect the conductor [wire].”
Can I mix 12 and 14-gauge wire?
How many outlets can you put on a 14 2 wire?
14/2 wire on a 15-amp circuit can power 8 receptacles. Since most outlets have 2 receptacles, you can typically wire 4 outlets to a single 15-amp circuit using 14/2 wire.
How many receptacles can be on a 20 amp circuit?
One rule of thumb is to assign a maximum draw of 1.5 amps to each receptacle, which allows for 10 receptacles on a 20-amp circuit. You must use 12-gauge wire to connect 20-amp circuits; when you’re installing receptacles in the bathroom, kitchen, laundry room or outdoors, they must generally be ground fault interrupting receptacles.
What appliances require 20 amp circuits?
What 110-VAC equipment you’re using at different times of the day.
What size wire for 20 amp circuit?
The best wire to use for 20 amp is the No. 12 AWG wire. This wire will safely carry 20 amps up to 100 feet. If you plan on going over 100 feet, or if you want to run the wire in conduit, you should upgrade to 10 gauge copper wire.
Can I use a 15 amp GFCI on a 20 amp circuit?
You can use a 15 amp GFCI on 20 amp circuit because it uses less power than that circuit is capable of putting out. However, it’s essential to know that a dedicated twenty amp circuit with only one outlet requires a twenty amp ground fault circuit interrupter (GFCI).
