Environment:
Electrical distribution systems

Cause:
Correct orientation is necessary

Resolution:

A. Primary connections:
If load is connected to OFF end of circuit breaker, connect load
neutral to H1 terminal of neutral CT.
If supply power is connected to OFF end of circuit breaker, connect
supply neutral to H1 terminal of neutral CT.
B. Secondary
