Re: What about the CableCos and SatCos? said by cdru:I can't quote the exact passage, but my guess is that the NEC requires cable, telephone, and power lines to be grounded at the entrance of the premises. That is my guess too - it is based on copper cables coming into the premises, and has not been updated to reflect non-conducting cables (such as fiber) and therefore the whole thing is a joke.
If someone wires you house for sound with copper wires, does NEC require the amplifier be grounded? So long as no copper wires go outside the premises, I see no reason to require grounding to a rod for an ONT.
The only possible rational explanation is there is a chance that currently, or in the future, copper phone or TV cable will be run outside the house, and hence the grounding requirement.

| NEC 800.100 is the section that covers grounding of metallic sheathed communications cables. You can view a free copy of the NEC here. Follow the link towards the bottom that says view the 2008 version. Free registration required.
Coax cabling would be covered under this section. As an overwhelming majority of ONTs are installed on the exterior of the house, there would be an entry point for the coax.
I can't argue for or against if something should be grounded. I'm going to defer that to people that know much more about that type of thing then I. However, regardless of if it should be, the point is that it currently is required by NEC. The NEC gets updated every couple of years (it was just updated this year) and fiber connections aren't new. |

kudos:2 | Ok, so if they put the ONT inside the house no need for a ground - no metallic sheathed communications cables. |

kudos:5 | Possibly, but I don't know. And interior ONT installs are definitely the exception to the rule. |
