Power Cable
Overview
As an option, you can add 150- or 225-amp sub-feed output circuit breakers () to the two (2)
mounting bracket positions provided on your 150kW InfraStruXure PDU. These circuit breakers
offer a means for distributing higher blocks of power to other equipment. If your PDU has already
been configured with a subfeed breaker(s), refer to “How to connect the sub-feed cable to the circuit
breaker” on page 56. To install a new circuit breaker, follow all of the instructions in this section.
Caution
The PDU must be powered down before adding a subfeed. For instructions on
ensuring total power off, refer to “How to Ensure Total Power Off” on page 33 of this
manual.
