3 Phase Wild Leg

[InspGadget]

When doing a safety inspection at a laundromat, the attendant complained of a problem with one of the outlets. It turns out that the installer (unknown) of a branch circuit never checked for voltage at main panel and hooked it up to the wild leg of a three phase service. He did a nice job of installing conduit and wiring but neglected to check the voltage (I guess) and put 208 volts into a duplex outlet. It was tagged out and a real electrician corrected the problem.

I can see it now, installer "But I put my little 3 prong doo-hickey into the receptacle and got two little orange lights."

"Sure, they were burning a lot brighter than usual, but I thought that meant I did an extra good job."

I did that once in haste to finish a job and turbo-charged a band saw.

Did the same thing and blew up that little light tester in my hand. only good for 120v.
