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 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).
Note
Any customer-specified, hard-wired, multi-circuit power cable that is installed by an
electrical contractor must be installed with a 3-pole circuit breaker.
