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. Circuit Breaker The Marked Electrical for the 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. The server contains four C20 power receptacles located at the bottom rear bulkhead. A minimum of two power cords (A0-A1) must be used to maintain normal operation of the server. A second set of two cords (B0-B1) can be added to improve system availability by protecting, for example, against power source failures or accidentally tripped circuit breakers. The server can receive AC input from two different AC power sources. System AC Power Specifications Power Cords Table 2-5 lists the various power cables available for use with the server. Each power cord is 15 feet (4.5-m) in length with a IEC 60320-1 C19 female connector attached to one end.

Circuit Breaker
The Marked Electrical for the 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.
The server contains four C20 power receptacles located at the bottom rear bulkhead. A minimum
of two power cords (A0–A1) must be used to maintain normal operation of the server. A second
set of two cords (B0–B1) can be added to improve system availability by protecting, for example,
against power source failures or accidentally tripped circuit breakers. The server can receive AC
input from two different AC power sources.
