For a 90 amp breaker, it is recommended to use a #3 AWG copper wire with a maximum allowable ampacity of 100 amps for residential wiring. Using the correct gauge wire ensures safety and prevents overheating. Make sure to consult the National Electrical Code (NEC) and local building codes for specific requirements.

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.


Can 13 gauge wire be connected to a 20 amp breaker?

No, it is not recommended to connect 13 gauge wire to a 20 amp breaker. The wire gauge should match the amp rating of the breaker to prevent overheating and potential fire hazards. In this case, a 20 amp breaker should be used with at least 12 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.


What gauge wire used for a fifteen amp breaker?

AWG # 14 copper.


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?

It is not recommended to connect a 14 gauge wire to a 12 gauge wire on a 20 amp breaker, as this can create a safety hazard. It's important to match the wire gauge to the circuit breaker rating to prevent overheating and potential fire hazards. It would be best to run a continuous 12 gauge wire for this circuit.
