2.2.2.2 Facility Power Requirements and Characteristics
For proper redundancy, the facility must have two independent power sources. That
is, circuit breakers must be connected either to separate power company utility feeds
or to an uninterruptible power system (UPS). For power redundancy, the power
cables must not be connected to the same facility power source.
