Can you use a 25 amp breaker with 12 gauge wire?
A 12 gauge wire is rated for 25 amps.
NEC only allows for it to be protected at a max of 20 amps (unless following an exception for motor loads)..
What can I run off a 30 amp breaker?
In a typical RV with a 30 amp electrical service some of the power hungry appliances and portable devices are the air conditioner, electric water heater, microwave, coffee maker, electric skillet, hair dryer, space heaters and a toaster.
How many outlets can be on a 30 amp breaker?
There is no limit to how many receptacles can be put on a circuit in a residence. In a commercial setting there is a limit to how many receptacles can be on a circuit but 120 volt 15/20 amp receptacles still cannot be on a 30 amp breaker. Receptacles must be 30 amp rated such as is used for an RV.
How many amps can a 12 gauge wire handle?
20 AmpsIn accordance with US electrical codes the max current for circuits utilizing 12 gauge wire is 20 Amps. However, 12 gauge copper wire is capable of handling much higher currents. There is something called fusing current, the current at which a wire will melt.

Is a double pole 30 amp breaker 60 amps?
A main breaker is a large-amperage double breaker, same as any double breaker in the breaker box, except it supplies power to each busbar. So your question is like asking if you can draw 60 amps off a 30 amp double breaker … the answer is NO.
How many amps will 12/3 wire carry?
The NEC prohibits use of an overcurrent device exceeding 20 amps with #12 wire. I know that’s not what you wanted to hear, but the NEC sets this limit because #12 wire will overheat if you make it carry more than 20 amps. This is generally what causes house fires attributed to the electrical system failure.

Can you use 6 gauge wire 30 amp breaker?
Re: 6 gauge wire to a 30 amp breaker Oversized wire gauge size is not a problem, as long as it fits properly beneath the breaker lugs and does not need to be modified or altered to fit. Oversized breaker size is a problem.
Can you put a 30 amp breaker in place of a 20 amp breaker?
But in general the answer is “No, do not go and put a 30 amp breaker in place of a 20 amp breaker because the wiring is most likely ‘sized’ for the 20 amp load and -may- overheat if a 30 amp load is used with wiring sized for a 20 amp load.”
Can 12 gauge wire handle 20 amps?
12-gauge wire is the next size larger and is allowed to carry up to 20 amps. As a result, the amp rating of a circuit breaker has the following relation to the wire size that has been chosen. A 20-amp breaker is never* allowed to run any circuit whose wires (anywhere on the circuit) are 14-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.
Will a 12 2 wire carry 30 amps?
12 gauge wire is designed to carry no more than 20 amps. No. You may be able to use 10 AWG, but even that is not safe for 30 A under all circumstances. You need an electrician to look at what you are doing.
Can a 14 gauge wire handle 20 amps?
So yes, a 14 gauge wire will safely carry 20 amps, no problem. … You get 50% more current capacity with 12 gauge wire compared to 14 gauge wire. So the 12 gauge wiring would trip immediately if there was a dead short. A 14 gauge wire would not trip the breaker and it could smolder for a while.
