FAQ:

Q: What AWG do use for a 30 amp circuit?

A: The reality is that the rule of thumb is that you need a gauge wire size of 10 for 30 amps. So yes, you can use a 10 gauge wire for 30 amps, but you can’t use a 12 or 14 AWG for this amount of power as it simply cannot handle it. Can 10 gauge wire handle 40 amps?

Q: What is a 30 amp circuit breaker used for?

A: The Square D by Schneider Electric Homeline 30 Amp Two-Pole Circuit Breaker is used for overload and short-circuit protection of your electrical system.

Q: What size wire would you use on a 30amp breaker?

A: 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.

Q: Can I plug my 30 amp RV into a 50 amp outlet?

A: You can plug a 50 amp RV into a 30 amp electrical service — that’s not a problem. First, you’ll need a 50 amp female to a 30 amp male electrical adapter (a dog bone). The adapter will allow you to plug right in to the power source. There are different variations of these adaptors.
