Introduction
Your Rheem/Ruud Transfer Switch is supplied with this
combined “Installation and Operator’s Manual”. This is an
important document and should be retained by the owner
after the installation has been completed.
Every effort has been expended to make sure that the
information in this manual is both accurate and current.
However, the manufacturer reserves the right to change, alter
or otherwise improve the system at any time without prior
notice.
For the Home Owner
To help you make informed choices and communicate
effectively with your installation contractor(s),
Read and understand the Owner Orientation Section
of this manual BEFORE contracting or starting your
transfer switch installation.
To arrange for proper installation, contact the store at which
you purchased your Rheem/Ruud transfer switch, your
dealer, or your utility power provider.
The Transfer Switch Warranty is VOID
unless the system is installed by a
licensed electrical professional.
Owner Orientation
The illustrations are for typical circumstances and are meant
to familiarize you with the installation options available with
your transfer switch.
Local codes, appearance, and distances are the 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.
• Follow a regular schedule in caring for and using your
transfer switch, as specified in the manual.
Installer Responsibilities
• Read and observe the safety rules.
• Read and follow the instructions given in this manual.
• Check federal, state and local codes and authority
having jurisdiction, for questions on installation.
• Ensure generator is not overloaded with selected loads.

Equipment Description
The transfer switches are intended to transfer the entire load
of normal residential installations when used with the
supervisory contacts provided. The load is connected either
to utility power (normal) or home standby power
(generator). The transfer switch monitors utility and
generator voltages and will automatically connect to the
appropriate source of power.
These switches make it easy for a licensed electrician to
complete a home standby installation. The unit contains
utility service disconnect circuit breaker, generator
disconnect circuit breaker and automatic transfer switch in
one enclosure. Service conduit and conductors can be wired
directly from your meter to the transfer switch. A separate
disconnect and associated wiring are not required when
installed per applicable federal, state and local codes,
standards and regulations.
Major components of the transfer switch are a 2 pole utility
disconnect circuit breaker, a 2 pole generator disconnect
circuit breaker, a 2 pole double throw transfer switch, control
circuit board, fused utility terminals and interconnecting
wiring. The control board also has two inputs for current
transformers that sense generator current.
The transfer switch is solenoid-operated from utility or
generator inputs and contain suitable mechanical and
electrical interlock switches to eliminate the possibility of
connecting the utility service to the generator output. It has
ratings capable of switching full utility power into the
residence. In addition, a manual override lever is provided
for the transfer function.
The control circuit board has active circuits sensing utility
and generator voltages. It creates a signal for the generator
start-up, switch transfer and retransfer when utility is
restored. The control board also contains red and green
LED’s indicating the power sources available and two relay
operated contacts that provide supervisory control of
external loads.
