What size circuit breaker for GFCI circuit in a normal size bath?
Normally it is a 20 amp using AWG 12/2 gauge wire. But it really depends on what size wire is on that circuit. If it is white AWG 14 gauge then use a 15 amp breaker. If it is yellow AWG 12 gauge then use a 20 amp breaker.
What is the margin of safety with selecting circuit breakers?
The NEC requires that if the intended rating of a circuit corresponds to a standard size breaker then that size breaker must be used. In most instances, "rating of a circuit" means the intended connected load plus 25%. If the intended rating of a circuit does not correspond to a standard size breaker, you can go up to the next standard size without any other adjustments. In most circumstances, besides what I've already stated, a 14 gauge copper wire cannot be connected to a breaker larger than 15 amps, 12 gauge copper to a 20 amp breaker, and 10 gauge copper to a 30 amp breaker.
Is it safe to use 10 gauge wire on a 20 amp breaker for a microwave?
No, 10 gauge wire requires the use of a 30 amp breaker. A 20 amp breaker is only used on 12 gauge wire.
Can you wire 10 Gauge and 12 Gauge in the same circuit?
Yes but there are two stipulations, one that the join or splice must be made in a junction box that is accessible and has a removable cover and the second stipulation is that the breaker that is supplying the power can not be larger that the smallest conductor. In this case no breaker larger that a 20 amp breaker as #12 wire is only rated at 20 amps..
Can a double pole circuit breaker be used for 2 different circuits I have a 20 amp double pole breaker want 2 circuits running 14 gauge wire?
can a 20 amp double pole circuit breaker be used for 2 different 120 v circuits using 14 - 2 wire
14 gauge wire can be on what size circuit breaker?
A 14 gauge wire is typically used on a 15 amp circuit breaker. It is not recommended to use a larger circuit breaker with a smaller wire size as this can create a fire hazard.
How should I properly wire a 30 amp breaker for my electrical circuit?
To properly wire a 30 amp breaker for your electrical circuit, you should use the appropriate gauge wire (typically 10 gauge for a 30 amp circuit), connect the wire to the breaker terminal, and then run the wire to the outlet or device you are powering. Make sure to follow all local electrical codes and safety guidelines when performing this task.

Can you connect 14 gauge wire to 12 gauge wire on a 20 amp breaker if the 14 gauge is the end of the run and dedicated to lights?
yesAnother (corrected) answer.NO! The circuit breaker is there to protect the wiring from overheating. It wouldn't matter where on the circuit you decided to put the 14 gauge wire, you would need to change the breaker to 15 Amp if you did that. Using 14 gauge wire on a 20 amp circuit is a fire hazard and contrary to UBC. Contact your local building and zoning department to verify.
What gauge wire should be used for a 30 amp breaker?
For a 30 amp breaker, a 10-gauge wire should be used.
What gauge wire should be used for a 60 amp breaker?
For a 60 amp breaker, a 6-gauge wire should be used.
What amp is suitable for 10 gauge wire?
A 30-amp circuit breaker is typically suitable for 10-gauge wire.
Where is power window circuit breaker for 1989 Toyota Cressida?
Not circuit breaker only fuses in cars that are used. Driver side kick panel 7.5a gauge fuse check it fist.

What gauge wire should be used for a 40 amp breaker?
For a 40 amp breaker, a 8-gauge wire should be used to ensure safe and efficient electrical flow.
What gauge wire should be used for a 50 amp breaker?
For a 50 amp breaker, a 6-gauge wire should be used to ensure safe and proper electrical connection.
What gauge wire should be used for a 15 amp circuit?
For a 15 amp circuit, a 14-gauge wire should be used.
