GE Industrial Solutions ProTrip Conversion Kits AK-50, AKU-50, AKS-50, AKT-50, AK-75, and AK-100 - Manual (Page 16)

AK-50 & AKS-50 Draw-Out Breakers
The fourth-wire disconnect for AK-50 and AKS-50 draw-
out breakers mounts to the lower back frame, as shown
in Figure 25.
• If the terminal board is already present on the
breaker, just replace the control harness. Maintain
the following color code: white wire to common,
black wire to the tap.
• If the disconnect must be added, mount it as shown
in Figure 25.
AK-75 & AK-100 Draw-Out Breakers
There are two fourth-wire disconnect designs used with
these breakers. One design is used on breakers for GE
type AKD switchgear, while the other applies to breakers
for GE types AKD-5 and AKD-6 equipment. The only
difference is the bracket used for mounting the
disconnect to the breaker. Figures 26 and 27 show these
two designs.
The conversion kit contains an assembled, ready-to-
install mounting block and bracket for AKD-5 and AKD-6
installation, plus an addition bracket only for type AKD
equipment installations. For AKD equipment, remove the
bracket from the assembled disconnect and replace it
with the AKD bracket.
The fourth-wire disconnect for AK-75 and AK-100 draw-
out breakers mounts to the lower back frame as shown in
Figure 28.
• If the terminal board is already present on the
breaker, just replace the control harness. Maintain
the following color code: white wire to common,
black wire to the tap.
• If the disconnect must be added, mount it as shown
in Figure 28.
