Branch Circuits and Circuit Breakers

Integrity NonStop NS-series modular cabinets contain two PDUs. Each of the two

PDUs requires a separate branch circuit of these ratings:

Branch circuit requirements vary by the input voltage and the local codes and

applicable regulations regarding maximum circuit and total distribution loading. Select

circuit breaker ratings according to local codes and any applicable regulations for the

circuit capacity.

Enclosure AC Input

Enclosures (such as processor slice, processor switch, IOAM, and so forth) require:

Each PDU is factory wired to distribute the phases to its receptacles, Refer to Modular

Cabinet PDU Phase Distribution on page 3-5. Factory-installed enclosures are

connected to the PDUs for balanced load among the phases.
