Grounding a Cold Water Pipe
1. Drill the clamp to accept a two-hole ½ inch hardware lug. You can also connect the water
pipe by attaching the ground conductor using an approved water pipe clamp.
2. Scrape clean the area of contact to the cold water pipe with the clamp. The area must be free
of paint, rust and/or corrosion and coated with an approved anti-oxidation compound before
the clamp is attached to the pipe.
3. Locate the clamp on the interior of the building, within five feet of the cold water pipe entry
point into the building, without any flanges, or pipe connections between the ground clamp
and the pipe building entry point.
Note This is required to ensure good continuity to ground at the point of pipe contact and
building entry.
4. If the connection is made on the output side of the water meter, you can install an electrical
jumper (minimum 4/0 AWG) around the meter to another clamp to provide a continuous path
to ground, in the event the water meter is removed for service.
Building Steel Option
When attaching to building steel for a grounding path, use exothermic weld connections installed
per manufacturer’s recommendation.
Antenna and Coax Grounding - Rooftops
The rooftop antennas (including the GPS and WAN antennas) are grounded by their mounts
and by the ground kits on the coaxial cable connected to the CGBs (Coax Ground Bars).
Warning! Do not install separate antenna ground connections unless specified by the
antenna’s manufacturer.
Grounding antennas on rooftops
1. Bond each antenna mount/mast to the CGB with No. 2 AWG BTCW exothermically welded
to the mast and connected to the ground bar with an approved two- hole ground lug.
2. Install coax ground kits as close to the antennas as possible, just before the antenna
jumpers, and then bonded to the CGB.
Note: If the site configuration is such that the coax runs horizontally along the rooftop
and then vertically down the side of the building to the close mount antennas, Do Not
Install antenna masts or coax ground connections at the antenna.
