I’ve recently realized the station we are working at (additional construction). Operates from 480v ungrounded delta system. As many others I’m sure that I just never knew about than but have Just learned about recently. And I understand that even if a phase fails nothing with happen with an ocpd until a second fault occurs, than with that happening you have a 480v fault on your hands. But I have two questions I haven’t been able to find exactly to my likings to know for sure. 1. If you touch any 1 phase to ground will you still receive a shock?
And 2. I know that you still have to pull an egc with all the 480v ungrounded circuits, and I know you must have detectors to show something event of losing a phase. But wondering how they work and where are they usually located?
