Check AC power and ground for CMC1

The coupled bonding conductor (CBC) provides mutual inductance coupling between the CBC and the 
telephone cables exposed to lightning. The conductor can be a 10 AWG (#25) (6 mm

2

) wire tie wrapped 

to the exposed cables, a metal cable shield around the exposed cables, or 6 spare pairs from the exposed 
cable.

For a high-rise building, connect the CBC to an approved building ground on each floor. To provide the 
coupled bonding protection:

Connect one end of the conductor to a telephone cable building entrance protector ground that is 
connected to an approved ground.

Route the conductor next to the exposed telephone cables being protected until it reaches the 
cross-connect nearest to the telephone system.

Position the unexposed telephone cables at least 12 inches (30.5 cm) away from exposed 
telephone cables whenever possible.

Terminate the other end to the single-point ground block provided for the telephone system.

The AC power cord may connect to a properly rated power-distribution unit, individual AC power 
receptacles, or to a UPS.

See 

 on page 365 for CMC1 

single-cabinet routing, 

page 366 for CMC1 2-cabinet routing. Routing power cords for a 3-cabinet configuration is similar to 
routing the 2-cabinet configuration.

To connect and route the power cords:

Ensure the AC load center’s circuit breakers are OFF.

Connect the cabinet to an “unswitched” or “always-on” electrical outlet.
