Thanks for the tips guys. Those PP10's look like they would be worth the cost if you were running multiple conduits. Here's another question: I will be doing 2 other roof penetrations for an HVAC unit and a roof mounted ventilator. Do I need to install a receptacle at each location or will just 1 for everyting be okay? Thanks again bob
Bob, The required receptacles should be within 25' of the a/c equipment based on 210.63.(guess the cmp must have felt that hvac servicemen don't carry 100'ext.cords on their trucks)
