WHEN ISOLATING THE D/B TO TEST FOR I/R SHOULD YOU LOCK OFF THE MAIN ISOLATOR AS WELL AS THE MAIN SWITCH IN THE D/B OR ARE YOU OK WITH JUST THE MAIN SWITCH BEING LOCKED OFF?? JUST THINK THAT IF YOU ONLY LOCK OFF THE MAIN SWITCH AT THE D/B THERE IS A CHANCE OF STICKING YOUR PADLOCK KEY INTO THE INCOMERS OUCH!! NOT DONE 3 PHASE TESTING BEFORE SO HOPE THIS MAKES SENSE?? GOT A TEST ON MONDAY JUST WANT TO MAKE SURE!!
