Question

outdoor 50A receptacle


my boss wants me to install a 50A recept on the outside corner of a house in order to operate a welder. the welder will be plugged in when used & then unplugged when not in use. since this is an outdoor application, it must be GFI protected, but a regular indoor GFI seems superfluous in this case, not to mention the wire size im running is too large to land on the GFI terminals. i believe i need a GFI breaker for the panel, is that correct?

Did you already tell your boss you knew how to do this?

Suggest the boss hire a licensed electrician. Just tell him that you are unable to do it. If you want to educate yourself on the codes regarding, you can get a copy of the NEC, or look through it at NFPA.org for free. 50 amp gfci breakers are expensive. Here is some listings at nextag.com http://www.nextag.com/50-amp-breaker-gfci/stores-html

A regular GFI receptacle would only be rated up to 20 amps.

You should follow the advice and tell your boss to hire someone.

Why do you believe this circuit should be GFCI protected?

Well., I can see where this is going and I will suggest that you get a electrician do this due you are working for your boss at the customer house there is few issue will arise.

Why not just rent a gaz powered welder/generator unit if you do need to use the welder for short time.

Merci,
Marc

Tell your boss to stop being cheapskate and hire someone qualified to do this.

I did not think that a 50A 240v circuit meets the conditions which require a GFCI....am I wrong? My references are for 120v 15 or 20 amp circuits only in specific wet areas and / or outdoors. Have I missed something?

Only for a spa Missouri Bound. Welder, just a normal circuit. I would think that the welder would trip the gfci anyways, due to the nature of the beast.
