One circuit breaker lift truck is required for each:

• Two-high line up.

• Switchgear installed on concrete pads that do not extend beyond the front of the switchgear.

• NEMA 3R outdoor nonwalk-in switchgear.

The cradle is raised and lowered by a self-braking worm and pinion drive system with a winch and wire cable. No ratchet release or locking is required because of the automatic load-retaining clutch feature. Rotating the handle clockwise raises the cradle. Rotating the handle counterclockwise lowers the cradle.

Follow the instructions provided with the Masterclad lift truck to remove a circuit breaker from the circuit breaker compartment with the lift truck.

An optional wall-mounted test cabinet (see Wall-Mounted Test Cabinet (Optional)) is furnished when listed in the user’s specifications. The test cabinet consists of a small enclosure with:

• A power on-off toggle switch,

• a white light indicating the power is on,

• A red light indicating the circuit breaker is closed,

• A green light indicating the circuit breaker is open,

• Close and open pushbuttons, and

• An eight ft. (2440 mm) cable with a secondary control receptacle that can be plugged directly into the circuit breaker control plug.

Refer to the customer drawings for the external power connections and requirements necessary for the cabinet. A convenient terminal block is provided inside the test cabinet for these connections.
