4.4-Breaker Conversion
There are two 4th-wire disconnect designs used with these
breakers. One design is used on breakers for AKD Type
equipment. The other design is used on breakers for AKD-5/6
Type equipment. The difference in the designs is the bracket
used for mounting the disconnect to the breaker. Figure 4-3
depicts the two designs.
The Conversion Kits are shipped with the AKD-5/6 Type
assembled with only the bracket for the AKD Type. If an AKD
Type is required, remove the AKD-5/6 Type bracket and
replace it with AKD Type bracket.
