Supervisory Control Wiring
1. Terminal strip on control module in transfer switch
has four connections for customer use. There are two
sets of “Normally Closed” contacts available. They will
be activated when generator power is required. These
can be used for supervisory control of large connected
loads on generator. Loads will be allowed to operate if
there is enough generator power available.
NOTE: There are two wireways provided to keep the
supervisory loads separated from each other.
2. Terminals “A-A” on control module are rated for
24 VAC and air conditioner contactor control. Contacts
are connected in series with the air conditioner
contactor control circuit.
3. Terminals “B-B” on control module are rated for 5 Amp
250 VAC and installer supplied contactor to control a
large load. Example: electric hot water heater. Contacts
are connected in series with the contactor control circuit.
4. Tighten all wire connections/fasteners to proper torque.
See inside transfer switch enclosure for proper torque
values.
Wiring Interconnections
All wiring must be the proper size, properly supported and
protected by conduit.
Complete the following connections between the transfer
switch, main distribution panel, utility power and generator,
as shown on the next page.
WARNING
Low voltage wire cannot be installed in same
conduit as power voltage wiring.
• Failure to follow above warning could cause personal
injury, damage and/or malfunction of equipment.
High Voltage Wiring
1. Ensure utility power is turned OFF. Connect utility
feeder conductors to transfer switch terminals marked
“UTILITY CONNECTION”. Connect utility live to “N1”
and utility neutral to “N2”.
2. Connect distribution panel feeder conductors to transfer
switch terminals marked “LOAD CONNECTION”.
Connect live to “T1” and neutral to “T2”.
3. Connect distribution panel Ground conductor to the
transfer switch “GND” terminal.
NOTE: Assure grounding electrode conductor is connected
and bonded per applicable federal, state and local codes,
standards and regulations.
Generator feeder conductors are shown below:
4. Connect generator feeder conductor from the generator
circuit breaker terminal “E1” to transfer switch terminal
marked “GENERATOR CONNECTION” terminal “E1”.
This conductor should pass through hole of current
transformer before making the connection.
5. Connect other generator feeder conductor from the
generator circuit breaker terminal “E2” to transfer
switch terminal marked “NEUTRAL”. This conductor
should pass through hole of current transformer before
making the connection.
6. Connect a cable from transfer switch terminal
marked “Neutral” to transfer switch terminal marked
“GENERATOR CONNECTION” terminal “E2”.
7. Connect a cable from transfer switch terminal marked
“Neutral” to transfer switch terminal marked “Ground”.
