INSTALLATION

PLACING THE CIRCUIT BREAKER IN THE

CELL

DANGER

Hazard of fire, explosion, severe injury, death and property damage. Circuit breaker must be OFF before installation or removal from cell.

WARNING

Circuit breaker contains powerful springs. Discharge springs completely before installation or servicing.

Before attempting to install the circuit breaker in the cell, verify that the continuous current, voltage and interrupting ratings are correct for the power system.

Open the B9 grease provided and apply a coating to the ends of the six (6) primary stab fingers (Fig. 17).

A portable lifter should be used for the insertion or removal of the circuit breaker if the compartment is above floor level. Place the breaker on the lifter and bring it to the same level as the cell. Align the hole on the lifter tab with the welded nut on the cell base and remove the holding pin from the right hand side of the cell base. (Fig. 18).
