Use AWG 12/2 with ground.
No, you should not run 8 gauge wire on a 50 amp breaker. The wire size should be compatible with the amperage rating of the breaker to ensure safety and prevent overheating. For a 50 amp breaker, you should use a minimum of 6 gauge wire.
No, it is not okay to replace a 20 amp breaker with a 40 amp breaker. Breakers are designed to protect the electrical wiring in your home, and using a higher amp breaker can overload the circuit and create a fire hazard. Always use the correct amperage breaker for the circuit.
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, in home wiring as long as it is protected by a 15 amp breaker. Remember this circuit will only handle 1800 watts and cannot be loaded to any more than 1440 watts. So if each light is 75 watts then the maximum you can install is 19.
You could if it fit properly in the connector, but it would be massive overkill since you only need 12 AWG wire. You also have to make sure the load can physically accommodate that larger size wire. Every so often someone will replace an electric cooktop witha gas one. All of the new gas cooktops require a 110v outlet. The old electric cooktop may have been run with a 50 amp breaker (and probably 6 gauge wire) In order to convert this 220 v circuit to a 110v circuit we change to a 20amp breaker. Depending upon the brand of breaker sometimes the wire will fit into it. If not, we splice on a short piece of 12 gauge wire and then connect to the breaker.
To properly wire a 20 amp breaker in a residential electrical system, follow these steps: Turn off the main power supply to the circuit. Choose the appropriate wire size for a 20 amp circuit (typically 12-gauge wire). Connect the wire to the breaker terminal and the neutral bus bar in the electrical panel. Install the breaker in the panel and secure it properly. Connect the other end of the wire to the outlet or device you are powering. Test the circuit to ensure it is working correctly and safely.
To wire a 30 amp breaker correctly, first turn off the power to the circuit. Then, connect the hot wire to the breaker terminal, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar. Make sure to follow the manufacturer's instructions and local electrical codes for proper installation.
To wire a 50 amp breaker correctly, you need to first turn off the power to the circuit. Then, connect the hot wire to the breaker terminal, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar. Make sure to follow the manufacturer's instructions and local electrical codes for proper installation.
To wire a 30 amp breaker correctly, first turn off the power to the circuit. Connect the hot wire to the breaker terminal, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar. Make sure the wires are securely connected and the breaker is properly seated in the panel. Turn the power back on and test the circuit to ensure it is working correctly.
To replace a 15 amp breaker, first shut off the main power to the circuit box. Then, remove the cover of the circuit box and unscrew the old breaker. Disconnect the wires attached to the old breaker, connect them to the new 15 amp breaker, and securely screw it in place. Finally, turn the main power back on to restore electricity.
No, this is not a recommended procedure. The breakers main job is to protect the wire that is connected to it. A 20A breaker will have a #12 wire (rated 20A) connected to it. A 30A breaker will have a #10 wire (rated 30A) connected to it. As you can see if you use a 30A breaker on a #12 wire you could overload the wire by 10 amps. I have seen an incident where the insulation has melted off of an overloaded wire, the wire short out and a fire start before the bigger size breaker tripped. DON'T DO IT.
To properly wire a 30 amp breaker in your electrical panel, you need to first turn off the main power supply. Then, connect the hot wire to the breaker terminal, the neutral wire to the neutral bus bar, and the ground wire to the ground bus bar.
