The site building shall provide a safety ground and protective earth for each AC service entrance to all
cabinets.
Install a protective earthing (PE) conductor that is identical in size, insulation material, and thickness to the
branch-circuit supply conductors. The PE conductor must be green with yellow stripes. The earthing
conductor described is to be connected from the unit to the building installation earth or if supplied by a
separately derived system, at the supply transformer or motor-generator set grounding point.

The Marked Electrical for the HP Integrity rx8620 Server is 15 amps per line cord. The recommended circuit
breaker size is 20 amps for North America. For countries outside North America, consult your local electrical
authority having jurisdiction for the recommended circuit breaker size.
