the breaker type and rating against the job drawing.

NOTE: Si un disjoncteur est rejeté par les pins

coulissants, vérifier de quel type est le disjoncteur ainsi

Breakers

Prior to Installation


Prior to lifting a breaker to its intended compartment

location, observe the following precautions:

Precautions:

1.

Check the compartment to ensure that it is free of

foreign objects.
2.

Verify that the breaker is the correct type for that

compartment.
3.

Ensure that the breaker is OPEN.

4.

Apply a thin fresh coat of GE lubricating grease

D6A15A2 to the breakers primary disconnects.
5.

Ensure that the racking forks on the breaker are

correctly positioned for initial engagement with the

pins in the compartment. To do this, insert the

racking handle and rotate it fully counterclockwise.














Précautions:

• Vérifier le compartiment afin de s’assurer qui’il est

libre d’objets étrangers.

• Vérifier que le disjoncteur est du genre correct pour ce

compartiment.

• Assurez-vous que le disjoncteur est en position OPEN.

• Appliquer une mince couche fraîche de graisse

lubrifiante GE D6A15A2 aux débranchements

primaires du disjoncteur.

• Assurez-vous que les cames de montage du disjoncteur

soient positionnées correctement en vue de

l’engagment initial avec les goujons du compartiment.

Pour ce faire, insérer la poignée de montage et lui faire

effectuer une rotation complète dans le sens des

aiguilles d’une montre.

Installation Procedures

To install the EntelliGuard circuit breaker, proceed as

follows:

1.

Carefully place the breaker in front of the section in

which it is to be installed. See Fig. 5-4.

2.

Open the breaker compartment door by rotating the

door latch assembly ¼ turn clockwise.

3.

Using the switchgear hoist or a suitable lifting

mechanism and the appropriate spreader, raise the

breaker above the elevation of the rails. See Fig. 5-5.

The lifting spreader for 800A, 1600A & 2000A AKR

breakers cannot be used with 800A, 1600A & 2000A

EntelliGuard breakers.

WARNING: Do not stand under the circuit breaker

during the hoisting operation.

ADVERTISSEMENT: Il est interdit de se tenir sous le

disjoncteur durant l’opération de levage.
