Ground wire connects to the ground bar, white wire connects to the neutral bar, and black wire connects to the breaker. Be sure and turn off main breaker before installing the wire or the breaker.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
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
Yes as long as you change the 50 amp breaker to a 15 amp breaker. You will be hard pressed to get the 50 amp #6 wire under the terminals of the 15 amp receptacle.
Use a 15 amp breaker and 14 AWG wire and all switches and outlets rated at 15 amps or greater.
If you are referring to house wiring then the answer is no. A breaker protects the wire size that is connected to the breaker. In home wiring most homes are wired with a #14 wire which is rated at 15 amps. That is why the wire is protected by a 15 amp breaker. The correct wire size to connect to a 40 amp breaker is a #8. This size wire is too large to connect to receptacles an light fixture terminals.
You use the correct size breaker depending on the size wire in the circuit. If the circuit is wired with AWG #12 wire use a 20 amp breaker. If it is wired with AWG #14 wire then use a 15 amp breaker.
Use 15 amp breaker with 14 gage wire or 20 amp breaker with 12 gage wire. Either way will work just fine.
A 225 amp load will physically not be able to tie into a 15 amp breaker and a duplex receptacle as you can not get a 3/0 wire under the breaker and receptacle terminal screws.
no
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.
Not unless you change the wiring for that circuit. The breaker protects the wiring and if you install a 40 amp breaker on a 15 amp wire circuit you will have a fire in your home.
All depends on the size of the existing wiring. If you have a 30 amp breaker on AWG #14 wire then this is an unsafe condition that must be corrected. 15 amp requires that the wire be AWG #14. If the wire is #15 then you can and should install a 15 amp breaker. 30 amp breakers are used on AWG #10 wire.
