For an existing older busway (70's, I-Line, 3,000A) that feeds floor to floor from the main to one mechanical panel up many floors, I would like to test the insulation for safety's sake.
I believe that I can de-energize the building, turn off the breaker feeding the busway, turn off all breakers in the mechanical panel, and then megger to the busway to recheck the insulation.
Is there a problem with doing this or doing it in this way? The busway is bolted to bus in the gear - it does not have taps.
Your help is greatly appreciated!
Cheers,
Joe
P.S.
I am not the guy who will be doing the megging, I am the guy who is determining the best way to test the busway - so please don't think that I am going to go and do this myself and get hurt (that is what I would I would think if I read this..)
