This may be a off topic of the site but I thought since I have gotten help here before that I might ask.
I was changing a 480v 3phase motor about a week ago and all Power comes from allen bradley bucket while troubleshooting motor I read all three leads Top of Fuse to ground L1 to ground Read roughly 480v L2 read 480v And L3 Read 0v.The entire motor control center all buckets read the same way.Even on other working and running equiptment.An amp reading showed that all legs on running equiptment were drawing ballanced load.
I have taken Voltage readings in many places and diffrent jobes but I have never seen this before expecting 277 to ground on each leg.lead to lead they all read 480v am I missing something or is this common in certian applications
