Drawout Case Test Plug


The DOC Drawout Case Test Plug provides an easy way to measure current and provide test access to GE style drawout case relays and meters.

The DOC features normally-closed internal contacts. Upon insertion into the case, it brings the internal drawout case contacts out for easier access.

Current Measurement Probes serve to redirect current circuits without disturbing them.

Disconnect pins can be used to disable specific contacts and short-circuit currents.
