Yes, the rating of a #8 conductor is 40 amps. There might be a problem of getting the wire under the terminal point on the breaker. The only time that this will happen in reality is when the load is at a long distance from the distribution point. The conductor size has to be increased to over come voltage drop on the circuit to the load.

Can you use 10 gauge wire to connect a 2 15 amp outlets to a 30 amp breaker?

No, it is not safe to use 10 gauge wire with a 30 amp breaker as the wire is not rated for that high of a current. It is important to use the correct wire gauge that matches the breaker amperage to prevent overheating and potential fire hazards. For a 30 amp breaker, you should use at least 10 gauge wire.


What gauge wire and amp breaker do you use on a stove dryer and hot water heater?

For a stove, use a 8 or 6 gauge wire with a 40 to 50 amp breaker. For a dryer, use a 10 or 8 gauge wire with a 30 amp breaker. For a hot water heater, use a 10 or 8 gauge wire with a 30 or 40 amp breaker. Be sure to consult local electrical codes and guidelines for specific requirements.


Could you use a 12gauge wire for a 25 amp breaker single pole?

No, a 12-gauge wire is typically rated for a 20 amp circuit. To safely handle a 25 amp breaker, you would need to use a 10-gauge wire. It's important to match the wire gauge to the amperage rating of the breaker to prevent overheating and potential fire hazards.


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.


Is a 12 gauge wire on 20 amp breaker safe for a sub panel?

No, a 12 gauge wire is rated for 20 amps, which matches the breaker size. It is not recommended to use a wire that matches the breaker size as it can result in overheating and potentially cause a fire hazard. Consider using a thicker wire, such as 10 gauge, for the 20 amp breaker to ensure safety for the sub panel.
