Is grounding the TV cable system to the electrical meter permitted?
Thanks
It is required
Are you sure?
done all the time and the phone company too.
**250.94 Bonding for Other Systems. **
An intersystem bonding termination for connecting intersystem bonding conductors required for other systems shall be provided external to enclosures at the service equipment or metering equipment enclosure and at the disconnecting means for any additional buildings or structures. The intersystem bonding termination shall comply with the following:
(1) Be accessible for connection and inspection.
(2) Consist of a set of terminals with the capacity for connection of not less than three intersystem bonding conductors.
(3) Not interfere with opening the enclosure for a service, building or structure disconnecting means, or metering equipment.
(4) At the service equipment, be securely mounted and electrically connected to an enclosure for the service equipment, to the meter enclosure, or to an exposed nonflexible metallic service raceway, or be mounted at one of these enclosures and be connected to the enclosure or to the grounding electrode conductor with a minimum 6 AWG copper conductor
(5) At the disconnecting means for a building or structure, be securely mounted and electrically connected to the metallic enclosure for the building or structure disconnecting means, or be mounted at the disconnecting means and be connected to the metallic enclosure or to the grounding electrode conductor with a minimum 6 AWG copper conductor.
(6) The terminals shall be listed as grounding and bonding equipment.
Thanks! I also thought that. Yesterday a local Power Company said this a NO NO on the electrical meters in Kansas City.
Thanks again
The bond is required. Your local jurisdiction might have requirements as to the preferred method. Newer construction will have a dedicated grounding terminal for this purpose.
Many power companies restrict the cable and phone companies from using the meter pan. The reason was that many of the devices used restricted the opening of the enclosure as stated in item number 3 that Joseph Whitt posted above. In my area they had to go back and replace the existing meter pan clamps with approved clamps that did not restrict the operation of the cover.
The bonding is required although it does not need to be done at the meter. The utilities may also limit the use of the meter pan.
