4.4 Connecting Alarms
Depending on the model being installed, the fuse platform will have either of two types of alarm
connectors on the rear side of the platform:
• Screw-down barrier terminal strip
• Wire wrap pin
Figure 16 shows the two types. Connect the connectors as follows:
• Screw-down barrier terminal strip: The terminal screw size is 3-48. Terminate wire leads
with crimp-on spade lug or ring connectors that have a maximum width of 0.200 (5.080
mm) or use #16 to #30 AWG copper wire without lugs (insulation stripped back). In
selecting wire size, follow local code referring to the ampacity guidelines provided in
Appendix A of this manual.Tighten the terminal screws to approximately 9 pound-inches
(1 Newton-meter) of force.
• Wire-wrap terminal: Wrap terminal block pins using #22 to #26 AWG copper wire with
insulation stripped back. In selecting wire size, follow local code referring to the ampacity
guidelines provided in Appendix A of this manual.
