Mounting Tube Accessory For OEM Breaker
Cassette
Part number 0275B8280G001
The OEM cassette is equipped with a black plastic
racking handle storage tube. If you have an OEM
cassette the plastic part needs to be removed and
this part needs to be installed. To identify an OEM
breaker, the sixth character in the 20-digit catalog
number will be 1, 2 or 3 if it is an OEM breaker. If the
sixth digit is a D, then it is an AKD-20 cassette.
Hardware for mounting the metal tube is already in
the cassette. The nut needs to be loosened, slide in
the tube from the side and retighten the nut to 25 lb-
in. See figures 6 and 7
