Ideal For
Not Recommended For
Connect secondary terminals 1S1 and 1S2 for the main metering/protection winding; if a second winding exists, use 2S1-2S2. Never open-circuit the secondary of a CT while energized - hazardous voltage. Ground the secondary circuit at one point only, preferably at the switchgear earth bar. Ensure shorting and grounding facilities are provided before disconnecting the CT from the load.
