VCP-W Testing

The VCP-W breaker IB includes information on all the recommended tests for the breaker. If you have a 75kA VCP-WG, VCPW-HD, or 38kV VCP-W (not HD), refer to the IB for the specific breaker type. All tests should be done using an AC source. A DC source can be used, but cannot definitively show a failure, as this type of test can produce false negatives.

Additional information can be found in the Visual Instruction Booklet Essentials (VIBE):
