Issue:
How the TOC works and how can be identified?
Product Line:
Metal Clad Switchgear.
Environment:
Metal Clad, VR Breaker.
Cause:
Understanding how the standard Metal Clad offer works.
Resolution:
Truck-operated contacts indicate the physical position of the circuit breaker in the compartment. They indicate whether the circuit breaker is in the connected or test/disconnected position.
The TOC unit does not distinguish between the circuit breaker being in the test/disconnected position or withdrawn completely from the compartment.
The TOC unit is mounted on the right side of the horizontal steel barrier in the top of the circuit breaker section. It is operated by a spring-loaded lever. This lever is activated, just before the circuit breaker reaches the connected position, by a pin on the upper right side of the front cover of the circuit breaker.
