Title: NEMA 15-50 receptacle
Post by: Mike Sokol on July 27, 2017, 03:52:38 PM
I just came back from a site survey for a gig this weekend. I have my choice of plugging into a bunch of ceiling mounted 20-amp Edison receptacles on an undetermined amount of circuit breakers, or a single NEMA 15-50 receptacle in the hallway. The 15-50 would be perfect for power except that's a 3-phase/208-volt outlet with 3 hots and a ground, but no neutral. My goose is cooked at this point since a lot of the stage gear is 120-volt only. I think it's generator time...

At least it's stamped correctly  ;) could have been a 14-50 ran 3 phase  :o

There's a hotel in my area that does this.  Their "distro" bonds N->G for functionality, but not safety.

Another reason to run that "little mixer" on 208-240  :)
