5.3 Removing the circuit breakers

Warning: Do not stand under the circuit breaker
during the lowering operation.

Advetissment: Ne restez pas sous le disjoncteur
pendant l'opération de descente.

Caution: When using the switchgear breaker lifting
device, do not unwind the cable completely from
the drum. To lift the breaker, turn the device
operating crank clockwise. To lower the breaker,
turn the device operating crank counter-clockwise.

Prudence: Lorsque vous utilisez le dispositif de
levage du disjoncteur de l'appareillage électrique,
ne déroulez pas entièrement le câble. Pour lever le
disjoncteur, tournez la manivelle du dispositif dans
le sens des aiguilles d'une montre. Pour abaisser le
disjoncteur, tournez la manivelle du dispositif dans
le sens inverse des aiguilles d'une montre.

To remove the EntelliGuard circuit breaker,
proceed as follows:

1. Open the breaker by pressing the

OFF/OPEN button.

2. Use a slot screwdriver the open the racking shaft

door by turning clockwise. Insert the racking
handle and rotate it counterclockwise until the
breaker travels from CONNECT through TEST
to the DISCONNECT position, as shown by the
position indicator. This operation should be
performed with the door closed. If the breaker
closing spring is fully charged, it will be
automatically discharged when the breaker
is moved to the WITHDRAWN position.

3. Open the compartment door and fully extend the

draw-out rails. Roll breaker out to rail stops. This
is the WITHDRAWN position.

4. Before proceeding, visually check the breaker's

spring charge and close indicators to verify that
breaker is open and the springs are discharged.

5. Attach the lifting device and raise breaker off

draw-out rails.

6. Push the draw-out rails back into the

compartment.

7. Pull the breaker forward until the primary

disconnects clear the compartment.

8. Lower the breaker onto a flat surface free of

protrusions that could damage the breaker's
internal parts.

9. Close the breaker compartment door. If the

circuit breaker will be removed from the
compartment for an extended period of time.
An optional dead front cover, catalog #GFUTDF,
may be ordered and installed to prevent access
to live conductor parts.
