These retrofill breakers are designed to rack into a special Cassette with a hollow back. The special cassette is
equipped with AK style 7 point bullet connectors which interface with the original AKD-5/6 secondary disconnect
blocks. The cassette also has a new racking mechanism. Two cams in the cassette engage pins on the new breaker
to pull it into the cassette. The new breaker for AKD-5 has tubular primary disconnects and AKD-6 breakers have
primary disconnect fingers which will directly connect to the primary disconnects in the AKD-5/6 switchgear.
1. Check to see that the breaker or breakers match their respective compartments.
2. Read the breaker summary sheet, the front view drawings, breaker nameplate, and the identification card on the
breaker shipping carton.
3. To match the breaker to its proper compartment, refer to the breaker location list on the old original switchgear
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 numbers.

Clean and Grease Breaker

1. Before installing or operating a breaker, refer to the EntelliGuard G Breaker DEH-41304 instruction manual for
pre-operation inspecting and testing.
2. Check thoroughly for any damaged or loose parts and for any dirt or foreign matter which may be on 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 Mobilgrease 28 (D50HD38) to the primary disconnect fingers
for better electrical connections on the breaker. Part # 193A1751P1 is a 1 oz. tube of this grease.

WIRING
• Before installing the breaker, the
secondary disconnect bullets on the rear
of the cassette must be wired to the
EntelliGuard secondary disconnects on
the front of the cassette.
• Wires with wire markers are provided on
the retrofill. Make sure that the
switchgear wiring connection points
match up with the original wiring of the
cubicle. This ensures that all wiring
connections are properly made.
Wrong connections will cause the breaker
to malfunction.
