Owner Orientation
The provided illustrations deplict typical circumstances
and are meant to familiarize you with the installation
options available with your transfer switch.
Local codes, appearance, and distances are factors
that must be considered when negotiating with an
installation professional. As the distance from the
existing electrical service increases, compensation in
wiring materials must be allowed for. This is necessary
to comply with local codes and overcome electrical
voltage drops.
The factors mentioned above will have a direct effect
on the overall price of your transfer switch
installation.
NOTE: Your installer must check local codes AND
obtain permits before installing the system.
Read and follow the instructions given in this manual.
Installer Responsibilities
• Read and observe the safety rules.
• Read and follow the instructions given in this
manual.
• Check federal, state and local codes, standards and
regulations.
• Ensure generator is not overloaded with selected
loads.
INTRODUCTION
Equipment Description
This transfer switch is intended to operate electrical
loads found in normal residential installations. The load
is connected either to utility power (normal) or home
standby power (generator).
The manual transfer switch is equipped with two main
circuit breakers ("GENERATOR SUPPLY" and
"UTILITY SUPPLY") and a mechanical interlock. The
"GENERATOR SUPPLY" circuit breaker connects
power from the generator to the load devices wired to
the manual transfer switch. The "UTILITY SUPPLY"
circuit breaker connects utility power from the
distribution panel to the loads wired to the manual
transfer switch. Each of these circuit breakers have an
isolated neutral that MUST be connected inside the
transfer switch.
The mechanical interlock allows the circuit breakers for
either the generator power "GENERATOR SUPPLY" or
the utility power "UTILITY SUPPLY" to be turned on to
provide power to the selected house loads. This
switching neutral manual transfer switch will not allow
utility line power and generator power to be connected
to a load device at the same time.
If utility line power is restored while generator power is
being used, there will be no effect on the generator or
transfer switch components. When utility power is
restored, follow the instructions in the section "System
Operation" .
Generator Compatibility
Only use a generator that is factory-equipped with a
NEMA L14-20R or NEMA L14-30R receptacle, shown
in Figures 9 and 10.
• NEVER connect transfer switch to any receptacle other
than those recommended as damage to connected
appliances may occur.
