i can`t find any code article on concentric ko`s that says i need a bonding bushing,other than service equipment.do i need a bonding bushing with a feeder to a panel if the conduit is being used as the equipment grounding conductor?what if i have a seperate ground wire ?any help would be appreciated.
I'm sorry JMelectric. I should have at least said welcome to the forum. My bad.
Anyway, welcome to the forum. Take a look at 250.97 which addresses over 250V systems very clearly, then see 250.96 which addresses under 250V systems very not so clearly
