Probably a old topic, but Im installing a long tall riser that is partialy PVC with a RSC mast.....How do I properly bond the RSC? Never done this before.. Can I just fasten to the mast knob clamp bolt?
In ths area, a pipe ground clamp is attached to the GRS conduut and bonded at the POCO service attachment. POCO does all the work.
how did you do it??? any pics??
I just did one a week or so ago like that. What I did was add a lug to the long bolt that is part of the pipe weatherhead clamp, and used a nut to secure the lug.
I don't see that as code compliant. You're assuming that the bolt and the weatherhead is capable of carrying the potential fault current. I'm sure that the weatherhead was not tested for this or is not listed for that purpose.

similiar here. The pipe ground clamp is required, but POCO will attach to the POCO neutral for youAround here, you would have to run a bond with the conductors out thru the weather head and connect to a ground clamp around the riser. The bond would have to come from the bonding of the service.

I also see this as a problem, as odd as it seems that fitting would have to be listed for the purpose (250.8).
A simply grounding clamp onto the mast with a bonding jumper to the neutral at the weather head would be code compliant and how we would do it here if we wanted to keep the weather head. Usualy we do it per POCO specs for the steel riser at the pole, no weather head, just a bonding bushing at the top of the conduit packed with duct seal etc.
I don't see it yet... I'm sure the lug he installed is listed, and the bolt and nut seems to meet 250.8(A)(5).
It sounds to me as if he is using the weather head as a means to bond the raceway. It was not designed for that use and I doubt it is listed for that use.
