Yeah... hard to do though. Any ground helps. I used to do telco NIDS (actually we called them protectors back then) with #12 or #14 back in the day. I think #10 for an Ethernet surge protector is adequate. I know various regulatory authorities etc want a #6 it just is not practical to do for small devices. They treat a small surge protector the same as a power entrance ground.

Where outside facility telecommunication cables are configured for a standard entrance, the metallic members of all incoming telecommunication cables, including paired-conductor and optical fiber cable, shall be grounded (earthed) to the MGB, either directly or through a SSGB at the facility’s entrance point. Each metallic member shall be effectively bonded to the grounding point with a 16 mm2 csa (#6 AWG) or coarser green-jacketed grounding conductor, or with a transmission line ground kit, using bonding methods described within this chapter. "" So they say #6 AWG. I'm an unqualified rando on the internet, but I'd say if you grounded it with anything at all then you did better than most. ------ Original Message ------ From: "Steve Jones" <[email protected]> To: [email protected] Sent: 5/1/2018 11:40:15 AM Subject: [AFMUG] Smallest gauge shield to ground Whats the smallest gauge stranded ground i can use to bond bbdge copper shield to the ground lug on surge suppressors? Ive been using #8 but it gets cumbersome in a 12 port cross connect enclosure, i dont have footprint for a larger enclosure and my contractors hate my design
