2.6Cutoff Characteristics of Distribution Panel (At the time

of connecting power distribution box)

At the time of connecting the distribution panel through power distribution box, protection should be coordinated so that the breaker of the device (or power distribution box) trips before the breaker of the distribution panel trips. Such protection should be maintained. Therefore, the distribution panel should have the characteristic conditions shown in “TABLE 2.5 Characteristic Condition of Distribution Panel Breaker”. It is necessary to use Distribution panel Breaker suitable to these conditions.
