I was testing a 480 volt 3 phase panel to industrial metal working shop.
I was reading 480 volt to ground on 2 legs and less than 30 volt ac on the third leg.
I have worked in numerous locations industrial and have not seen. seems to be a grounded leg??
I called electric company whom came out and found nothing wrong so I look stupid on this.
Any one can explain the different configurations I have yet to run into and feel like a dumbass again.
Thanks, Rick
