The AC power pedestal or meter should be provided with a breaker to
protect the cable from the pedestal to the Power Cabinet. The Power
Cabinet rating is 130A. A 150 A breaker is recommended, or as
appropriate for local electrical code.
The AC Load Center (ACLC) is divided into two (2) compartments. The circuit breaker
compartment is accessible through the front of the Power Cabinet and contains all of the
AC circuit breakers. The rear compartment is accessible through the I/O area of the
Power Cabinet and contains all the connections for the AC Power Cabling to the Power
Cabinet.
The cable designations are referenced to Table 5-1.
Table 5-30 provides the quantity and description of the necessary
equipment required for AC Power.

CAUTION
– Dangerous voltages are present that can cause serious
injury or death. AC power wiring must be installed by
qualified personnel only.
– High Leakage current. Earth ground connection is
essential before connecting the power supply. Ground
connection is also required before connecting any
incoming telecom lines to ensure protection from
surges.
IMPORTANT
The Power Cabinet is rated at 130 Amps (100 Amps
continuous / 130 Amps non–continuous, in the range of
208–240V AC see Table 5-32 for details). Maximum
cable size that can be accommodated is 300 kcmil.
Cabling sizing should be determined by Local Electrical
Codes, using 90°C rated conductors, and derating for
50°C operation. Motorola recommends not less than 2/0
AWG (#1 BSWG; 50 mm
cables to the power pedestal, with an associated power
pedestal breaker size of 150 Amps for one Power Cabinet.
NOTE
The hole in the cabinet I/O panel is the proper size for a 2"
Trade size conduit fitting.
