CommScope Drop Cable - Manual (Page 33)

Run and Attach the Cable to the Ground Block/Buried Installation
NEC Article 820 states that the ground block should be attached to the wall as close as possible to the electri-
cal meter. Both the ground wire and the coaxial cable connections should run horizontally. The grounding wire
should be as straight as possible.
The preferred bonding method is to attach the ground block’s bonding wire to the
electrical meter ground wire with a wire not less than 14 AWG in size. For recommen-
dations regarding ground wires sizes, please refer to the National Electric Code (NEC
820-40) or your local building code. If bonding the ground block to the meter is not
possible, you may bond to an exterior metal cold water pipe running into the earth. As
a last resort, you may drive an 8’ ground rod into the earth and attach the bonding wire
to that, but you will need to ground ALL of the grounds of the residence to that rod.
Special Circumstances for Mobile Homes
Bond mobile homes at the electrical service tap. If there is no service tap, you may bond to the frame of the mo-
bile home using a wire no smaller that 12 AWG. NEVER bond to the siding of a mobile home.
Connectorize the Cable and Form a Loop
Once the ground is attached, cut the coax so that you
have a sufficient amount to reach the ground block com-
fortably plus about another 1’ (30 cm). Connectorize the
cable (see page 9.9/Coax connectorization.) and attach it
to the ground block, Then form a 6 inch (15 cm) diameter
loop and secure it with a cable tie. This extra cable will be
useful if you ever need to re-connectorize the cable.
