C.O. Ground Conductor Installation
Use an M6 double-hole lug on 5/8-inch center (Not provided) to terminate one end of the
Central Office (C.O.) ground conductor to the CPS shelf. Terminate the other end of the

top or bottom fed. 6 AWG is the maximum gauge that can be used with regular 5/8-inch
center lugs. To use 2 AWG, a suitable narrow tongue lug like the Burndy/FCI may be
evaluated.
