## What happens when you put a 20 amp receptacle on a 15 amp circuit?

If your question is “can I connect a receptacle rated for 20 amps to a circuit designed for 15 amps?”, the answer is yes, because the receptacle can handle more current than the circuit is rated for.

If you exceed 15 amps, the breaker will blow, and protect the receptacle..

## Can I use 14 gauge wire on a 15 amp circuit?

14-gauge wire has a smaller cross-sectional area than 12-gauge and would overheat on a circuit controlled by a 20-amp breaker if the circuit was passing the maximum current. … Because it has even less chance of overheating, 12-gauge wire is also acceptable on a 15-amp circuit.

## How many outlets can you put on 12 gauge wire?

One rule of thumb, and it’s just a rule of thumb, not a rule of law, is to put no more than 8 receptacles on a 15-amp circuit with #14 wire, or 10 receptacles on a 20-amp circuit with #12 wire. For each lighting fixture you add to the same circuit, subtract one receptacle (very roughly speaking).

## What is 12 gauge wire used for?

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

Yes you can mix 12 and 14 gauge wire with a 15 amp breaker on the circuit. But it is not recommended because the next homeowner or electrician may be confused and put a 20 amp breaker on it again.

## How many outlets can one GFCI protect?

A standard GFCI will protect up to 20 amps, drawn from any combination of receptacles, either the built-in one or any number of additional ones connected to its load terminals.

## Can I use 12 gauge wire on a 15 amp receptacle?

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.

## Can 14 2 wire be used for outlets?

14–2 wire is allowed for a 15 Amp circuit, and at 120 Volts, 15 Amps x 120 volts = 1800 volt-amperes. So that would allow ten (10) receptacles, you would probably derate that to eight (8) for an 80% safety factor.

## Can I mix 12 gauge and 14 gauge wire?

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 12 gauge wire on a 20 amp circuit?

For a 20 amp, you _must_ use 12 gauge to start with, 14 gauge doesn’t handle a 20 amp fuse at all. A 12 gauge wire is typically good for 15 amp at 100 feet. For your 160 feet, they suggest a 6 gauge.

## 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 you use 14 gauge wire on a 20 amp circuit?

6 Answers. I would say 14 gauge wire anywhere on a 20 amp circuit is not OK. The purpose of the breaker is to cut off power before the wiring overheats. If you plug in several devices on an outlet that total 20 amps, you will exceed the safe working capacity of the 14 gauge wire without tripping the breaker.

## Can a refrigerator be on a 15 amp circuit?

A refrigerator will use roughly half of the available amperage of a standard 15-amp circuit, and over one-third of a 20-amp circuit.

## How many outlets can you put on a 15 amp breaker?

10 outletsGenerally, homes have eight to 10 outlets on a 15 amp breaker but not all are used at the same time. Lights and outlets are normally wired on separate branch circuits, which means that the lights will be protected by a separate circuit breaker to the one which protects the outlets.

## Can I use 12 gauge wire for lights?

Yes, it is okay to use 12-2 cable to supply lighting fixtures. The other answer indicates that it even with 12-2 you have to use a 15A breaker for lighting circuits which is not strictly correct. If the entire circuit is 12AWG (other than fixture wires), then a 20A breaker may be used.
