I have to complete the grounding of (1) a Gastite line and (2) I not sure about the TW internet cable.
The building is serviced with a 150A sub-panel, properly grounded back to main 200A panel; compliant with sub-panel wiring and grounding rules.
The Gastite installation needs to be grounded: 12' of CSST from regulator to boiler and another 15' T'ed to kitchen range. I will be connecting a grounding clamp to the outlet side of the propane regulator and taking that 6 AWG jumper down the outside wall, buried next to the house, and eventually fished into the sub-panel about 10" away. NEC 250.70
The internet cable enters a metal wall box, where it is jointed using a grounding block to take a lighter coax indoors to the modem. The other day the TW installer insulated a 12 ga copper wire from the cable grounding block, out the front of the box, across the utility room wall, into the front door of the 150A panel and attached it to the ground bus. I guess he was trying to meet company requirements to ground the cable but assumed I would disconnect that ground wire as soon as he left.
Do I have to have my coax internet cable grounded?
If so, can I connect the smaller gauge cable ground wire to the 6 AWG ground wire with a proper wire-to-wire clamp outside the house so the cable ground wire piggybacks to the sub-panel ground bus?
I also expect to install a TV antenna and an FM antenna and would assume they also will have to be grounded back to main panel by bonding to the sub-panels ground bus. Is there a multiple bonding clamp that would allow several pieces of equipment to be tied in this way; outdoors and connected to the 6 AWG ground wire?
