NOTES:
1. For field wiring free-standing starters, the outgoing connection size is determined by
the starter size as listed under the “Outgoing Connection Size” column in Table 2.
Outgoing lugs are factory-connected to the motor on factory-mounted starters.
2. When wiring to a starter (either factory-mounted or free-standing) with an optional
disconnect switch or circuit breaker, the incoming lug size is determined by the device
size as shown in the above table. For standard power block, the incoming connections
are as shown in Table 2.
Medium Voltage, Solid State, Across-the-Line
Incoming and outgoing connections are crimp-type connectors, standard bus tabs are
NEMA 2.
Compressor Motor Connections
Power wiring connections at the motor are “spark plug” type terminals with threaded
copper bar, sized per the following table.
