Installation Procedures: Route and Attach Power Cables to the Racks

application) from the enclosure through the Liquidtite conduit to the PDU.

4. At the PDU, route the cable through the opening you created in step 1 and then up through the wireway () at either side of the PDU. This will allow you to connect the cable to the circuit breaker panel.

5.At the circuit breaker panel, cut the wires to the proper length, and connect the power cable’s individual wires:

a. If you have branch current monitoring installed, route each phase conductor through a current sensor. If it is a three-phase cable, route

the L1, L2, and L3 wires through a separate current sensor.

b. Connect the L1, L2, and L3 wires to the circuit breaker(s). The illustration below shows a three-phase cable connecting to three

single pole breakers; however, you can also connect a three-phase

cable to a three-pole breaker, or a single-phase cable to a single-pole circuit breaker.

c. Connect the neutral wire to the closest open termination point on the Neutral Bar (N).

d. Connect the ground wire to the closest open termination point on the Ground Bar (G).

Caution: Any multi-circuit power cable that is installed by an electrical contractor must be installed with a 3-pole circuit breaker.
