NPM Circuit Breaker Current Loads
Each NPM rack contains a power distribution panel (PDP). The PDP has up to
16 circuit breakers (CBs). Each breaker switch controls the power to a specific
NPM component. Individual NPM components can be powered off by setting
the appropriate breaker switch to the OFF (down) position.
Table 2.11 shows the maximum current loading of the circuit breakers in the
RFSS and radio rack PDPs.
