Need to get a 3/0 GEC from a main disconnect to a 2" water pipe and building steel.
My disconnect is located outside the building and would like to stub it into the building with 1" Ridged or EMT above a suspended ceiling. (cant use pvc)
Planning on using a single 3/0 from the disconnect into the building then tapping off to building steel then onto the water pipe.
I know I need to Bond each end of the raceway, not sure what to do at the disconnect, I believe the bonding jumper to the conduit still has to be sized off of 250.66. I have not had any luck finding a bonding bushing big enough for 3/0 on a 1" conduit.
Am I going about this right? Any ideas
Thanks
