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. Main- tain 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 equip- ment, remove the bracket from the assembled dis- connect 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. Main- tain 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.
