Can you have a 120v circuit on a 30 amp breaker?
No, electrical code typically requires that circuits be protected by a breaker that matches the wire size. A 30 amp breaker is typically used for circuits with larger wire sizes. For a 120V circuit, a 20 amp breaker is more suitable with appropriate wire size.
Can you put 20amp breaker on 10-2 wire?
No, you should match the breaker size to the wire gauge. A 10-2 wire is typically rated for a 30 amp breaker. Using a 20 amp breaker on 10-2 wire could result in overheating and a potential fire hazard.
What size wire and breaker do you need for a 5000 watt garage heater?
Look on the heater and see what amps it is pulling. That will determine the wire size and breaker size. It must be on a dedicated circuit. 15 amps = AWG # 14 wire with 15 amp breaker 20 amps = AWG # 12 wire with 20 amp breaker 30 amps = AWG # 10 wire with 30 amp breaker 40 amps = AWG # 8 wire with 40 amp breaker
How big of breaker do you use for 115 volt?
Depends on the wire size used in the circuit. If you use AWG # 14 wire you must use a 15 amp breaker. If it is wired with AWG # 12 wire then you use a 20 amp breaker. If a AWG # 10 wire is used then a 30 amp breaker is required. The breaker protects the wiring from overheating so you must use the proper size breaker for the wire used.
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.
