A single pole 15 amp breaker can only be setup for 120v. You need a double pole 15 amp breaker, which looks like two 15a breakers attached with a bar across the two actuators. Each leg provides 120v, or in the case of your breaker, 240v across the two legs.
Look to see if the 30 amp panel is fed with a two wire or a three wire. If it is a two wire then you are out of luck. If the panel is fed with a three wire then the panel should have the neutral terminated in the panel. It is this neutral that you need for 120 volt connections. You didn't state how many panel slots there are in the panel. If you are able install a 15 amp breaker into the panel and connect the wires going to the load. The black wire will go to the breaker and the white wire will go to the neutral bar in the panel.
Yes, a 20 amp breaker requires AWG # 12 copper wire. A 15 amp breaker requires AWG # 14 copper wire.
No, you should not replace a 15 amp breaker with a 20 amp breaker without consulting a licensed electrician. The breaker size should match the wire size to prevent overheating and potential fire hazards.
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.
A 15 amp breaker is not sufficient for a 225 amp load. You would need a breaker that matches the load current, such as a 225 amp breaker. Using a 15 amp breaker for a 225 amp load would cause the breaker to trip immediately due to overcurrent.
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.
If the full load amps rating of the motor on the name plate is exactly 15 amps you need to use # 12 wire. If it is a longer run you may have to go up one more wire size. The breaker size you need is 30 amps.
Use 15 amp breaker with 14 gage wire or 20 amp breaker with 12 gage wire. Either way will work just fine.
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.
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.
