5-4 Removing the EG-08/16/20 Circuit
Breakers
WARNING: Do not stand under the circuit breaker
during the lowering operation.
ADVERTISSEMENT: Il est interdit de se tenir sous le
disjoncteur durant l’opération de levage.
CAUTION: When using the switchgear hoist, do not un-
wind the cable completely from the drum. To lift the
breaker, turn the hoist operating crank clockwise. To
lower the breaker, turn the hoist operating crank counter-
clockwise.
ATTENTION: Il ne faut pas dérouler complètement le
câble du cylindre lorsque l’on utilisse le treuil du dispositif
de commutation. Tourner la manivelle opérant le treuil
dans le sens des aiguilles d’une montre pour soulever le
disjoncteur. Tourner la manivelle opérant le treuil dans le
sens contraire des aiguilles d’une montre pour abaisser le
disjoncteur.
To remove the EG-08/16/20 circuit breaker, proceed as
follows:
1. With the door closed and latched, press and hold the
trip button while sliding the racking cover open. Now
release the trip button.
2. 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 a few
turns before the end of racking action.
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WITHDRAWN position.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 drawout
rails.
6. Push the drawout 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. The
back of breaker will be resting on the interference pins
and guide.
5-5 Removing the EGS-32/40/50
Circuit Breakers
WARNING: Do not stand under the circuit breaker
during the lowering operation.
ADVERTISSEMENT: Il est interdit de se tenir sous le
disjoncteur durant l’opération de levage.
CAUTION: When using the switchgear hoist, do not un-
wind cable completely from the drum. To lift the breaker,
turn the hoist operating crank clockwise. To lower the
breaker, turn the hoist operating crank counter-clockwise.
ATTENTION: Il ne faut pas dérouler complètement le
câble du cylindre lorsque l’on utilisse le treuil du dispositif
de commutation. Tourner la manivelle opérant le treuil
dans le sens des aiguilles d’une montre pour soulever le
disjoncteur. Tourner la manivelle opérant le treuil dans le
sens contraire des aiguilles d’une montre pour abaisser le
disjoncteur.
To remove EGS-32/40/50 breakers, proceed as follows:
1. With the door closed and latched, trip the breaker.
2. Rotate the racking access cover in the door, 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.
3. Open the door, depress the spring discharge lever (Fig.
5-11) to discharge breaker's closing springs and then
fully extend the rails. While holding this lever de-
pressed, pull the breaker all the way out to its
WITHDRAWN position.
4. Before proceeding, visually check the breaker's spring
charge and close indicators to verify that the breaker is
open and the springs are discharged.
5. Attach lifting device to cutout notches in top wrap-
around frame of the breaker, using care to prevent
damage to the wiring.
6. Lift the breaker off the rails. Push the rails back into
the compartment.
7. Pull breaker forward until primary disconnects clear
the compartment. Lower breaker onto a flat surface
free of protrusions that could damage the breaker's
internal parts.
