For a 220 volt 100 amp breaker, you would typically need a wire gauge of 2/0 AWG (American Wire Gauge) or larger. It is recommended to consult with a professional electrician to ensure the proper gauge is used for your specific installation.

How do I wire a single phase 120 amp 230 volt flux and mig welder to a 200 amp panel?

It is very likely that the 120A current you quote is the output current. Check your Welder Box and look at the input current. It is likely around 30 Amps. To wire a 30A circuit you will need 10 gauge wire and it is likely 3 conductots + ground. You will need a 230V Breaker. Connect the black and red wires from the 10 gauge cable to the breaker, white wire to neutral and ground to ground.


What size main breaker do you need to run 10 gauge wire?

The size of the main breaker depends on the maximum current rating of the 10 gauge wire and the load it will be powering. Typically, a 10 gauge wire is rated for a maximum current of 30 amps. Therefore, a 30 amp main breaker would be suitable for running 10 gauge wire. However, it is important to consult local electrical codes and consider the specific load requirements before making a final determination.

Can you connect 14 gauge wire to 12 gauge wire on a 20 amp breaker if the 14 gauge is the end of the run and dedicated to lights?

yesAnother (corrected) answer.NO! The circuit breaker is there to protect the wiring from overheating. It wouldn't matter where on the circuit you decided to put the 14 gauge wire, you would need to change the breaker to 15 Amp if you did that. Using 14 gauge wire on a 20 amp circuit is a fire hazard and contrary to UBC. Contact your local building and zoning department to verify.
