To wire a double pole breaker with 10 2 wire, first turn off the power to the circuit. Connect the black and red wires from the 10 2 wire to the two terminals on the breaker. Then connect the white wire to the neutral bus bar and the bare copper wire to the ground bus bar in the electrical panel. Make sure to follow all safety precautions and local electrical codes.
A double pole 30 amp breaker can pass 30 amps per pole, therefore #10 wire should be used.
Remove the 30 amp double pole breaker and install at least one single pole 15 amp breaker. It is best if the other slot is not left open so if you have another single pole breaker of any size install it in the 2nd spot so it isn't open when you replace the cover on the panel. For your 15 amp circuit you need #14 gauge copper wire or larger with a hot, neutral, and ground. Your 30 amp circuit was probably wired with #10 gauge conductors. These will probably work on your 15 amp circuit but it may be difficult to connect #10 conductors to devices.
10/3 wire with 30 amp double pole breaker from panel box to water heater.
no. depending on length of run you'll need either 10 or 6 gauge wire for a 30 amp double pole breaker.
For 10-2 wire, you would typically use a 30-amp breaker. This size breaker is commonly used for 10-gauge wire in residential electrical installations. Make sure to check your local electrical codes and the manufacturer's recommendations for the specific application.
Yes it can be done that way. Just make sure to use a double-pole breaker to ensure each wire is on an opposite phase.
I assume you mean you are wiring a 220 volt circuit. You will install a 220 volt double pole breaker of the correct size for the circuit. An example would be for an electric dryer that requires a 30 amp double pole breaker wired with 10/3 wire. You connect the Red & Black wires to the breaker. One on each screw. You now connect the White wire to the neutral bus bar in the service panel. Then connect the bare copper ground wire to the ground bus bar in the service panel. At the dryer outlet connect the black & red to the hot screws, white to the neutral, and ground to ground. They will be labeled on the back of the outlet.
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.
No. In North America a double pole breaker is used to obtain a voltage of 240 volts from the distribution panel. What ever the amperage rating stamped on the handle of the breaker is, that is the amperage that the breaker will trip at.
