Thank you for purchasing a Generac Single Load Manual Transfer Switch to safely connect a portable generator to your
home or business (single phase only), recommended to be used as the disconnect panel for a single 120/240VAC load or to
feed a subpanel for multiple loads, see Installation Diagrams for typical installations. Use where the main electrical panel is
located indoors. This product is suitable for service entrance equipment.
READ THIS MANUAL THOROUGHLY. This manual has been prepared to familiarize personnel involved with the
installation of transfer switches with the manufacturer's installation requirements. Information and instructions con-
tained herein are not intended to replace or supersede, local, state, or national safety, electrical, and building codes
pertaining to such installations. Applicable laws, codes, and standards must always take precedence over the recom-
mendations contained herein. Always check with the local Authority Having Jurisdiction (AHJ) for the codes or stan-
dards that apply.
Only authorized dealers or qualified, competent installation contractors or electricians thoroughly familiar with applica-
ble codes, standards, and regulations should install this transfer switch. The installation must be in strict compliance
with all codes, standards, and regulations.
It is not intended that this manual be used by any unqualified person for the purpose of installing a transfer switch.
Installation, inspection, and testing of the system must be attempted only by competent, qualified electricians or instal-
lation contractors who are familiar with the equipment and with all installation codes and requirements.
It would be impossible to provide details for every installation configuration. For this reason, much of the information in
this manual is general in nature. Illustrations of typical installations are not intended to serve as specific installation
plans, but may be used in the planning and design process when considering the selection and purchase of a genera-
tor set for standby power applications. Always have the unit specific drawings and manuals on hand before beginning
any installation.
If a portable generator is used to power electrical load circuits normally powered by a utility

power source, it is required by code to install a transfer switch. The transfer switch must
effectively isolate the electrical system from the utility distribution system when the generator
is operating. Failure to isolate an electrical system by such means may result in damage to the
generator and may also result in injury or even death to utility power workers due to backfeed
of electrical energy.
After the transfer switch has been installed, do nothing that might render the installation in non-

compliance with such codes, standards, and regulations. Every effort was made to ensure that
the information in this manual was both accurate and complete at the time it was released.
However, the manufacturer reserves the right to change, alter, or otherwise improve this product
at any time without notice.
