Three-Phase Ac Usa Branch Circuit Requirements - HP StorageWorks XP12000 Site Prep Manual

Be sure to install Russellstoll 3934 (alternate, 9C34U0) or 3754 (alternate, 39R34U0W)
socket receptacles between the power distribution panel of the building and the power
plugs for the unit.
The power cords provided with the disk array are nonshielded, type ST or equivalent
with four #8 AWG (minimum) conductors terminated at one end with an assembled
plug connector.

Three-phase AC USA branch circuit requirements

To protect the disk array, your building must be wired correctly. Each supply ("hot")
conductor must be protected by a short-circuit protective device and by an overcurrent
protective device. The tables listed under the "AC line voltage requirements" heading
provide specifications for the overcurrent protective devices required for three-phase
operation.
All protective devices must comply with national standards of the country where the
units are to be installed. If a protective device interrupts any supply conductor, it must
also interrupt all other supply conductors.
Overcurrent protection is not required for the neutral conductor of this unit. Only 50 Hz,
three-phase configurations have a neutral conductor.
