## What wire do I use for a 30 amp breaker?

RULES OF THUMB. Many techs will repeat these rules of thumb and rely on them in all circumstances: “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].”

## How do you check if outlets are on the same circuit?

If the portable light goes off when you switch off any breaker, leave that breaker off. Go to the portable light and remove it from the first outlet. Plug the portable light into the second outlet. If the portable light does not go on, then the two outlets are on the same circuit.

## Will a 15 Amp saw trip a 15 amp breaker?

If it’s truly pulling 15 amps then yes. A 15A breaker will hold 80% of its current rating, which means at 12A, it will trip. That’s not how any breaker or fuse works. … If the device is rated at 15A, and it’s the only device running on the circuit, it should not be tripping a 15A breaker.
