I have a question.
Too many architects are not drawing in the cold water bonds.
In the new commercial building we just plumbed I had to provide a cold water line in the electrical room for the 600 amp. panel as a change order.
Could you tell me please how the N.E.C. states the requirements for what size of pipe and distance from meter for a cold water bond.
I fully understand the scope on single family homes,Thanks
At what Amperage would I need to increase my copper pipe size from 1/2 to 3/4
The reason I ask is because the Electrician asked for a 3/4 copper line with schedule 80 brass into eqpmt rm.Inspector said 1/2 would have been sufficient no brass needed.
Oh,and the electrician wanted the threads on the brass soldered.Not because I could not,it was just starting to become overkill.
This is going to happen again in the near future,so I would like to be able to get the correct piping to the correct location and save the future building owner some money.
