Wiring Detached Garage for 220v welder
This forum looks to me the right place to get some answers. Here goes,
I just purchase a Mig welder with 220v. The label on the welder states..Standard NEMA 6-50P 50Amps 220 volt. 220VAC Single Phase. Use 50 AMP Power Source with 6-50R.
In the main garage I have a 200 AMP panel. From the main panel to the "sub-panel", I have 4-#6 wire (Red, Black, White, and Green) The Red and Black is attached to a 50 amp 2 pole Square D circuit breaker. The 4-#6 wires run in a 1-1/2" gray conduit two feet under ground some 23 feet total to the "sub-panel" in the detached garage. The sub-panel has 6 shots for breakers.
I have four of those with 20 amp breakers for lights, garage door openers, etc. The two open slots will be for the 50 amp 2 pole breaker for the Mig Welder.
Here's what I have so far. The plug on the welder power cord in 3 prong 6-50P with red, black, and Green/yellow stripe (ground). I have the wall box with a 6-50R (receptacle. I intend on running 3#6 wires (red, black, green) from the 50 amp 2 pole breaker to the 6-50R (receptacle).
Question> Is this the correct way to complete the setup?
Thanks for your expert advice.
Sounds good to me.
You could change the breaker in the main to 60 amps if needed.
You could use two #6 for the hots and a #10 for the equipment ground(green).
