I am in the middle of installing a large trough system for tenant space meters and need some help with figuring out the bonding (and EGC) for the whole system.
Case is - No meter stacks permitted by local utility for 480V services. Opting for a main disconnect with a trough that will feed individual meters, Fused disconnect, and into individual tenant spaces. The attached diagram should explain it all.
I am using PVC as the conduit between the trough and the main. The conduit between trough and meter, and between meter and disconnect are all threaded galvanized nipples. I will be tapping the mains load side with insulated bugs to each meter socket with the appropriate size wire (#1 Alu for the 100A, and 4/0 Alu for the 200A).
My thinking is, I land my UFER ground and my main water bond at the 600A disconnect. From the bonded neutral kit within the main Dissconect, I run a #1cu to a terminal lug in the trough.
My question is, Do I need to run a bonding jumper from my Feeder disconnects to the trough or can I rely on the metal enclosures as an effective bond?
Any other comments or glaring errors that you would like to spring at me are greatly appreciated
Thanks
Sam
