Power feeders | HP Performance Optimized Data Center (POD) 240a

Power feeders

IMPORTANT: A licensed electrician must connect the power according to all local and national electrical codes, and must comply with manufacturer specifications.

Twenty-four power feeder couplings, twelve per IT section, provide the entrance for power to the HP POD 240e NA. The power feeders route into the top of each electrical panel on the end of the HP POD 240e NA.

Top view shown

The twenty-four power couplings are identified as either main power couplings or Adiabatic mechanical power couplings.

Main power couplings

•Each of the four main power panels contains four power feeder couplings, for a total of sixteen main power couplings.

•Each main power coupling has a 10.16 cm (4 in) diameter.

Adiabatic mechanical power couplings

•Each of the two Adiabatic power panels contains four power feeder couplings, for a total of eight Adiabatic mechanical power couplings.

•Each Adiabatic mechanical power coupling has a 7.62 cm (3 in) diameter.

Power feeders are sized in accordance with NEC and IEC regulations.
