Welding receptacle/plug

[jmellc]

Boss had me look at a battery charger Friday. 480/3ph. They want a cord & plug to plug into a welding receptacle nearby. I’ve seen this type before but never worked with them. Receptacle had no NEMA code, a big surprise. Boss is having to order. Hope we get the right matching plug. I sure don’t understand no NEMA code.

It's a Hubbellock® there is a number of ratings of them so will need to check what is there to match.
