A service riser was moved from the middle of the back wall of a house to the corner of the house when a swimming pool was placed in the backyard below the original drop. To gain clearance over the driveway now, a five foot length of metal pipe with service head attached, was run through the overhang using the proper service flashing bracket. The bottom of the bushed pipe riser was fastened with straps to the house for additional support. Service entrance cable was run from the middle of the back wall of the house from the original meter location. The SE cable was run up the wall and below the gutter a distance of twenty feet and fed through this short length of bushed pipe riser through to the service head where the service connection was made to the drop.

Do you think that the residential triplex service drop messenger cable joined with the aluminum neutal conductor wrapped twice around the ridgid metal pipe riser, metal to metal, is an adequate bonding means to satisfy 2005NEC 250.80?

And if not, what would be an adequate means?

(Would a #6 AWG bonding jumper, one end connected to a grounding clamp installed on the metal riser near the service head and the other end connected by means of a split bolt connector to the bare neutral conductor at the service point in the drip loop be adequate?)

Thank you
 
I think you need a pipe clamp on the riser at the weatherhead with the appropriate size bonding conductor. #4 copper for a 200 amp service-- I guess the #6 would work if this is only a 100 amp service. Of course you could just loop the neutral from the SE cable thru the pipe clamp connection and let it be.
 
Service raceway bonded?

Do you know of a manufacturer who makes a side-opening lugged, ground clamp for the above mentioned predicament? To slide the Neutral into the lug through the side opening and not to have to disconnect the Neutral to connect it to the ground clamp is a quickfix. Great idea.
Thanks
 
I am sure many manufacturer make them. Erico does but, of course, you will need a bigger one then what I have shown below.
