neutral sensor, as shown in Figure 4-3. The breaker
should not trip, and the alarm indicator, if supplied,
should not operate. Repeat the test on the other two
phases.
lf the system is a 3-wire system with no neutral current
sensor, apply the same current as described above
through any two phases of the breaker, with the connec-
tions exactly as shown in Figure 4-4. The breaker
should not trip, and the alarm indicator, if supplied,
should not operate. Repeat the test using the other two
combinations of breaker phases.
