What wire size is required for a branch circuit with 10 outlets and a 15 amp breaker?
With a 15 A breaker you need 14 Gauge wire. Normally you would only put 8 outlets on a 15 A circuit. If you have the option you shoudl consider a 20 A circuit, use 20A receptacles and 12 gauge wire. Comment: The question was on a homeowners electrical exam. My answer was also 14 gauge however, the tester said the answer was 12 ga. I thought maybe there was something special about the 10 outlets. For example, 10x180 VA per outlet/120V = 15 A which is right at the limit for 14 ga but would be 75% for the 12 ga wire.
What size of wire is needed to run a 20 amp 2 pole breaker for a 220 volt window AC unit?
For a 20 amp 2 pole breaker at 220 volts, you'd need a 12-gauge wire for a maximum run of 100 feet. If the run is longer than 100 feet, consider using a thicker 10-gauge wire to account for voltage drop. This wire size ensures safe and efficient operation for your window AC unit.
Can you connect a 8 gauge wire directly to a 10 or 12 gauge wire The appliance only requires 10 and 12 gauge but there is already 8 gauge running half way?
It is not recommended to connect wires of different gauges together, as this can create a safety hazard. It is best to use a connector or junction box to transition from the 8 gauge wire to the 10 or 12 gauge wire to ensure proper electrical connection and safety.
What size breaker is used with 10 wire?
For a 10-gauge wire, a 30-amp breaker is typically used for general household wiring. It's always recommended to consult a licensed electrician or local building codes to ensure the correct breaker size for your specific situation.
Which wire has a greater diameter a 22 awg or a 12 awg?
12 gauge is thicker. Household wires in the walls are mostly ga 14. Majority of wires in the car wiring are ga 16, except control wires which are thinner, like ga 18 or 20, and main battery wires wich are very thick, probably ga 4 or 6.
