The first and perhaps most crucial step is to turn off the circuit breaker.
Once it has been powered off, you need to place the two-pole breaker into the box.
Afterward, attach the flush mount box to the wall by screwing them together.
You will need a minimum of roughly 6 inches of wire inside the flux mount box.
Using your cable ripper, pull out about a foot of the wire’s plastic sheath to be used inside the circuit breaker box.
Connect the wires.
With your wire stripper, strip off one inch of the sheath at the tip of the wire.
Now, hook the wires with their respective screws.
Next, connect all the wires with the circuit breaker.
Once you have double-checked your work and ensured everything is properly connected, you can cover the circuit breaker box and plug in the welder.
