Ground Wire Terminal Lugs.
Ground wire lugs are provided in the
motor terminal box, and in the
starter panel.
Terminal Clamps. Terminal clamps
are supplied with the motor
terminals to accommodate either
bus bars or standard motor terminal
wire lugs. Terminal clamps provide
additional surface area to minimize
the possibility of improper electrical
connections.

Wire Terminal Lugs. Wire terminal
lugs must be field-supplied.
1. Use field-provided crimp-type wire
terminal lugs properly sized for the
application.
Note: Wire size ranges for the
starter-line and load-side wire lugs
are listed on the starter submittal
drawings supplied by the starter
manufacturer. Carefully review the
submitted wire lug sizes for
compatibility by the electrical
engineer or contractor.

2. A terminal clamp with a 3/8" bolt
is provided on each motor
terminal stud; use the factory-
supplied Belleville washers on the
wire lug connections.
Figure 27 illustrates the juncture
between a motor connection pad
and the wire terminal lug.
3. Tighten each bolt to 24 foot-
pounds.
4. Install but do not connect the
power lead between the starter
and compressor motor.) These
connections will be completed
under supervision of a qualified
Trane service engineer after the
prestart inspection).
Bus Bars. Install bus bars between
the motor terminals when a low-
voltage "across-the-line", "primary
reactor/resistor" or "auto
transformer" starter is used.
Be sure to jumper motor Terminal T1
to T6, T2 to T4, and T3 to T5.
Bus bars and extra nuts are available
as a Trane option.
Note: Bus bars are not needed in
medium or high-voltage applications
since only 3 terminals are used in the
motor and starter.
