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.


What is the wire size for a 35 amp breaker to a ac unit?

You will need to use #8 wire.


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


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.


What size wire and breaker do you need for a double oven rated 34.2 amp?

For a double oven rated at 34.2 amps, you would typically use a 40 amp double-pole breaker to accommodate the load. The wire size should generally be at least 8 AWG copper wire or 6 AWG aluminum wire, according to the National Electrical Code (NEC) guidelines. Always consult a licensed electrician to ensure compliance with local codes and safety standards.

What size breaker should be used for a double oven?

50 amp breaker wired with AWG # 6 wire.


What size wire for 75 feet of wire for a 30 amp 220 volt oven?

A 30 amp breaker run 75 feet would require you use AWG #10 wire. But, an oven normally pulls more that 30 amps and I would not use #10 wire on a 30 amp breaker for an oven. Normally any newer oven is wired with AWG #6 gauge wire on a 50 amp circuit breaker so the breaker will not trip during heavy use of the oven. Some older ovens could use a #8 wire on a 40 amp breaker.
