In cabinets without the optional rack-mounted UPS, each of the two PDUs requires a separate
branch circuit of these ratings:

1 Category D circuit breaker is required.
CAUTION: Be sure the hardware configuration and resultant power loads of each cabinet within
the system do not exceed the capacity of the branch circuit according to applicable electrical
codes and regulations.
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. Note that circuit breaker ratings vary if your system includes the optional
rack-mounted HP Model R12000/3 Integrated UPS.
These ratings apply to systems with the optional rack-mounted HP Model R12000/3 Integrated

Phase Load Balancing
Each PDU is wired such that there are three load segments with groups of outlets alternating
between load segments, going up and down the PDU. Refer to “Power Distribution Units (PDUs)”
(page 42). Factory-installed enclosures, other than the c7000, are connected to the PDUs on
alternating load segments to facilitate phase load balancing. The c7000 has its own three-phase
