Terminal Strips
Illustration 2 g00614345
Terminal Strip Lead Connections (1) Generator leads (2) Terminal strip (Bus Bar) (3) Plated washer Attach the generator leads (1) to terminal strip (2) in the following manner:
When more than one lead attaches to the bus bar, place the leads on each side of the bus bar. Use flat plated washer (3) under the bolt head and under the nut.
After connecting the leads to the bus bar, group all generator phase leads together. Tie these leads together.Ensure that there is a minimum clearance of 25 mm (1.0 inch) between uninsulated connections (phase to phase and phase to ground).Generator Lead To Other Lead

TOOLS NEEDED    
Part Number     Tool     Quantity    
5N-4685     Varnished cambric electric tape
15000 volt rating
105 °C (221.0 °F) rating     1    
5N-4686     Black vinyl plastic electrical tape
-40 °C (-40.0 °F) to
80 °C (176.0 °F) rating     1    When connecting the generator leads together or when connecting generator leads to a load lead, use the following procedure:
Fasten the generator leads together by using flat plated washer (1) under the bolt head and under the nut.
Apply two layers of varnished cambric high voltage tape. When the tape is being wrapped, the tape must be overlapped. The tape must be overlapped 50% of the width of the tape. Taping must extend length "B" onto the lead wire insulation. Length "B" is equal to 25 mm (1.0 inch).
Apply two layers of vinyl plastic electrical tape over the varnished cambric high voltage tape. Taping must extend length "A" onto the lead wire insulation. Length "A" is equal to 51 mm (2.0 inches).
The generator leads must not contact the sheet metal of the terminal box or any rotating parts. For each generator phase, group the leads together. Secure the leads together with cable straps.
