Power 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
(Figure 4, on 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.
1.
Ensure utility power is turned OFF. Connect utility
power supply leads to transfer switch terminals
marked "UTILITY CONNECTION".
2.
Connect utility neutral to the transfer switch
"NEUTRAL" terminal.
3.
Connect main distribution panel power leads to transfer
switch terminals marked "LOAD CONNECTION".
4.
Connect main distribution panel neutral lead to
transfer switch "NEUTRAL" terminal.
5.
Connect generator power supply leads from the
generator's control panel to transfer switch terminals
marked "GENERATOR CONNECTION". Each lead
should pass through hole of current transformer
before connection to contactor.
6.
Plug in current transformer leads into "CT1" and
"CT2" on control module.
7.
Connect generator Neutral from the control panel to
the transfer switch "NEUTRAL" terminal.
8.
Connect generator "GND" from the control panel to
the transfer switch "GND" terminal.
9.
Connect main distribution panel "GND" 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.
10. Connect generator utility 240 VAC terminals to
transfer switch utility 240 VAC terminals.
11. Tighten all wire connections/fasteners to proper
torque. See inside transfer switch enclosure for proper
torque values.

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. Example: air conditioner, hot water
heater, etc.. 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 for air
conditioner contactor control. Contacts are connected
in series with the air conditioner contactor control
circuit (Figure 5).

3.
Terminals "B-B" on control module are for installer
supplied contactor to control a large load. Example:
electric hot water heater. Contacts are connected in
series with the contactor control circuit (Figure 6).
