Electrical grounding requirements

Electrical grounding requirements
The server must be grounded properly for proper operation and safety. In the United States, you must install the equipment in
accordance with NFPA 70, National Electric Code Article 250, as well as any local and regional building codes. In Canada, you must
install the equipment in accordance with Canadian Standards Association, CSA C22.1, Canadian Electrical Code. In all other countries,
you must install the equipment in accordance with any regional or national electrical wiring codes, such as the International
Electrotechnical Commission (IEC) Code 364, parts 1 through 7. Furthermore, you must be sure that all power distribution devices used
in the installation, such as branch wiring and receptacles, are listed or certified grounding-type devices.
Because of the high ground-leakage currents associated with multiple servers connected to the same power source, Hewlett Packard
Enterprise recommends the use of a PDU that is either permanently wired to the building's branch circuit or includes a nondetachable
cord that is wired to an industrial-style plug. NEMA locking-style plugs or those complying with IEC 60309 are considered suitable for
this purpose. Using common power outlet strips for the server is not recommended.
