Hierarchy for Supply
Figure 8 shows a typical wiring hierarchy for the equipment power supply cabling.
Notice that the cable ratings are higher than the circuit breakers and fuse ratings. In this
example the circuit breaker rating has been de-rated to 70% of the cable maximum
continuous current rating.
