15 EntelliGuard R Circuit Breaker Retrofill AKD-8 Installation Manual DEH-41549 02/12
Check Before Installing
• It must be ensured that the supply power to
the compartment is turned off/ compartment
is de-energized for all the incoming and
outgoing circuits of the LVS prior to any work
being conducted on it.
• During the installation and related work on
the equipment, it must be ensured that the
operator is using the prescribed PPE for the
specified tasks.
• Ensure only qualified personnel install, operate, service, and maintain all electrical
equipment.
These breakers are supported on a rollout track in the same manner as the AK breakers. However, since the
rack-out mechanism is mounted on the breaker, there are no jackshafts in the enclosure. Racking arms on
both sides of the breaker frame engage the drawout mechanism pins fastened to both sides of the
compartment.
1. Check to see that the breaker or breakers match their respective compartments. Each breaker is
assigned a part or mark number.
2. Look on the breaker sheets summaries, the front view drawings, breaker nameplate, and on the
identification card on the breaker shipping carton.
3. To locate the breaker for its proper compartment, refer to the breaker location list on the front view
drawing. Find the proper breaker by the identification card on the breaker carton, or the mark number
on the breaker nameplate. All identical breakers have the same mark number.
Clean and Grease Breaker
1. Before installing or operating a breaker, refer to the breaker instruction manual for pre-operation
inspection and test.
2. Check thoroughly for any damaged or loose parts and for any dirt or foreign matter which may be in
the breaker.
3. Clean those areas if necessary with a clean, lint-free rag and isopropyl alcohol or acetone.
4. Be sure to apply a thin film of electrical grease (red, D50H47) to the contact areas (fingers) for better
electrical connections on the breaker ( Figure 7).
