Example 4 (single distribution panel)
In this example, the computer receives power from two or four separate circuit breakers in a single
power panel. This does not make use of the redundancy provided by the processor. It is, however,
acceptable if a second power distribution panel is not available.
This type of power distribution will result in system outage in the event of a power failure at either the
switch gear or the distribution panel. This power distribution is least recommended.
