I have a new pad mounted transformer with ten conduits going to a transclosure ( just a big JB with four busses). From there I have twelve conduits going into two new main services, six conduits to one and six to the other. The engineer is calling for each service to hit three new ground rods, plus water pipe and building steel. My question is related to bonding the metal sweeps(the pipes are pvc) that come up into the transclosure. I believe all I have to do is install a bonding jumper from each bushing to the transclosure and then land it on the neutral bus in the transclosure. Am I correct in that this is required per 250.80, as well as 250.142. Thanks for the input.
 
If the transclosure is properly bonded and you have no concentric/eccentrc knock-outs, you could bond the conduits with a grounding locknut.
A properly sized bonding jumper from a bonding bushing to the grounded buss would be acceptable also.
 
The transclosure is wide open on the bottom where the conduits stub up into. I was intending to put bonding bushings on all pipes, hit a foot lug on the transclosure, then go to the grounded conductor buss.
 
sounds plausible, however, I'm not familiar with a "foot lug"
 
sorry, it must be local slang. It's just a lug for a wire, or two or three etc. I'm sure you've used thousands of them. One example is Burndy type KA-U, it's for a single wire.
 
The bonding jumper from the bushing landing on the grounded buss sounds fine.
I'm not so sure the footlug connection would satisfy 250.102(C) in terms of sizing the jumper to the enclosure.
 
After reading 250.92 and 250.102 would I be correct in saying I can individualy bond each pipe to the grounded conductor buss based on 250.66, then i have to use 250.102(C)1 to bond the enclosure to the grounded conductor buss?
