Bob, would you mind elaborating ? This has always been a bit perplexing to me.
In reading 501.30 and 514.16 it would appear if I have a metallic conduit system from my pumps back to my service equipment I would need bonding means other than double-locknut.
Would this be regardless of a wire type equipment ground being installed ?\
If I take advantage of 514.8 Exception 2 and use PVC in my underground run and obviously have an equipment grounding conductor, what purpose does the 501.30 bonding serve going back to the service point ?
At my age, I'm accustomed to restaurants asking me to pay in advance, but now my bank has started sending me their calendar one month at a time.
