INSTALLATION

13.Unoccupied three−phase branch circuit breaker connection only. Verify that the branch circuit breaker is turned off. Be absolutely certain there is no power.

Attach a wire tap transition harness (supplied) to each of the phase A, B, and C connectors on the voltage harness.

Connect the wire tap transition harnesses to the appropriate phase connections of the unoccupied three−phase branch circuit breaker. Coil and secure any excess cable away from other conductors.

Proceed to Step 15 on page 23.
