Electrical Maintenance (Rev. 04/03)

A branch of T2 passes through the motor contactor to
become T3. A branch of T3 passes through the motor start
contactor and a start capacitor to become T3E, which is con-
nected to the third winding in one set. Another branch of T3
passes through the motor start contactor and a start capaci-
tor to become T3F, which is connected to the third winding
in the other set.
First and Second-Phase Connections
L1 and L2 supply power directly to the first and
second windings in both sets of windings in the motor
When the motor is starting under a load, the current in T1
and T2 climbs to a fairly high rate. When the current in T2-
T2A passes through the control coil of the current relay
exceeds 27 amps, the current relay is energized and its con-
tacts close.
