Thanks test for your input,
I will bring up the need for motor lead disconnection for high pot testing at our next electrical safety meeting.
We still have to find a suitable means for grounding though whenever we have to replace one of these motors, we use splicing kits for the motor...
Hello Test,
Yes we do need to ground the leads from the load side of the starter before we can disconnect the actual motor leads,on this type of starter the motor leads are bolted to the output from the starter in the bottom left of the cabinet,so after we have proved that there is no...
Hello all,
I am having trouble finding a suitable method of applying grounding clamps to our centerline motor starters, we have a bank of 4160V 600H.P motors controlled by Allen Bradley Centerline starters 5000V 3PH 1200A 260A max. when we have our motors periodically hi pot tested, we...
