Each chassis power supply should have its own dedicated branch circuit.
The circuit must be protected by a dedicated two-pole circuit breaker.
For North America, the circuit breaker should be rated at 20A.
For everywhere else, the circuit breaker should be sized according to the power supply input rating
and local or national code requirements.
The AC power receptacles used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground at the service
equipment.
