We are going to be pulling feeds from the PC transformer to our new 800A DP. All seemed well and good until today when we were told they have a fire pump hooked to the transformer and would not be able to shut the power down. This is a 120/208V transformer powering a 1200A MDP in the restraunt, a 5 story motel, 4000 W of street lighting, and apperantly a fire pump. Everyone else was willing to shut down for a few hours to pull the new service in but not the fire pump. I have a set of class 0 gloves, shoulders and arc shield. Would you recomend anything more substantial?
