There is 220 volts between the two poles. If you are running 2 wires (black and white) + ground then you hook black to one pole and white to the other. Put red or black electric tape on each end of the white wire and wrap around wire for 3 inches or so next to the connection so the next person will be able to see that the wire is hot and not a neutral.
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.
A circuit breaker does not have a wire fuse in it.
Assuming the wires are the correct gauge for application and breaker you use black and white wires as hot. Put red electrical tape on each end of white wire and connect red and black to the breaker output and bare wire to ground lug in panel. At receptacle connect black and red to hot contacts and bare wire to ground lug.
No. A 20 amp breaker needs 12 gauge wire.
The white wire would go to the neutral bar. Just be sure of the shunt trip voltage required for the breaker and land the white wire on the appropriate neutral bar in the correct panel.
Connect to the circuit neutral wire which should also be white.
If you are connecting 120 volts, you connect the black wire to the breaker, white wire to the neutral bar, and ground wire to the ground bar. If you are connecting 240 volts connect the black & white wires to the breaker, & ground wire to the ground bar.
To wire an AFCI breaker, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, snap the breaker into place in the electrical panel.
To wire a circuit breaker properly, first turn off the power to the circuit. Then, connect the hot wire to the breaker terminal and the neutral wire to the neutral bus bar. Finally, connect the ground wire to the ground bus bar. Make sure all connections are secure and the breaker is properly seated in the panel before turning the power back on.

To wire an arc fault breaker correctly, follow these steps: Turn off the power to the circuit you are working on. Remove the panel cover to access the breaker box. Identify the circuit where the arc fault breaker will be installed. Connect the hot wire to the breaker terminal and the neutral wire to the neutral bus bar. Connect the ground wire to the ground bus bar. Secure the breaker in place and replace the panel cover. Turn the power back on and test the breaker to ensure it is working properly.
To wire a GFCI breaker, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, turn the power back on and test the GFCI breaker to ensure it is working properly.
To wire a GFI (Ground Fault Circuit Interrupter) breaker, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, attach the breaker to the panel and turn the power back on.
To wire a GFCI breaker correctly, first turn off the power to the circuit. Then, connect the hot wire to the breaker's terminal, the neutral wire to the neutral bar, and the ground wire to the ground bar. Finally, turn the power back on and test the GFCI breaker to ensure it is working properly.
To install an AFCI breaker, first turn off the power to the circuit you are working on. Remove the panel cover and locate the breaker slot. Insert the AFCI breaker into the slot and connect the hot wire to the breaker terminal. Connect the neutral wire to the neutral bus bar and the ground wire to the ground bus bar. Secure the breaker in place and replace the panel cover. Turn the power back on and test the AFCI breaker to ensure it is working properly.

Secure the breaker in place and replace the panel cover. Turn the power back on and test the AFCI breaker to ensure it is working properly.
To wire a double pole breaker correctly, connect the hot wires to the breaker terminals and the neutral wire to the neutral bus bar. Make sure to follow the manufacturer's instructions and turn off the power before starting.
