AC Power Circuit Breaker Requirements for the MX960 Router

The circuit breaker protection on all the power supplies should be designed according to National Electrical
Code (NEC) of country of system installation or any similar local standard based on maximum drawn current
of the power supply specified in this document.
Each normal-capacity AC power supply has a single AC receptacle located in the chassis directly above
the power supply.
Each high-capacity AC power supply have dual feeds. One AC receptacle located on front panel of the
power supply while second one is located on chassis above the power supply.
Each high-capacity second-generation AC power supply has dual feeds. Both AC receptacles are located
on front panel of the power supply.
