Notes:
1. Connection appearances are shown in Figure 4-3
2. This is a simultaneous surge. The specified current is the resultant current (sum of terminal A and
terminal B) with respect to ground (terminal E).
3. The time interval between multiple applications should be 1 minute. In the case of pulse tests, the
polarity should be reversed between consecutive pulses.
