SAFETY RULES
This is the safety alert symbol. It is used to alert you to potential personal injury hazards. Obey all safety messages that follow this symbol to avoid possible injury or death.
The safety alert symbol (
) is used with a signal word (DANGER, CAUTION,WARNING), a pictorial and/or a safety message to alert you to hazards. DANGER indicates a hazard which, if not avoided, will result in death or serious injury. WARNING indicates a hazard which, if not avoided, could result in death or serious injury. CAUTION indicates a hazard which, if not avoided, might result in minor or moderate injury. CAUTION, when used without the alert symbol, indicates a situation that could result in equipment damage. Follow safety messages to avoid or reduce the risk of injury or death.
The manufacturer cannot possibly anticipate every possible circumstance that might involve a hazard.The warnings in this manual, and the tags and decals affixed to the unit are, therefore, not all-inclusive. If you use a procedure, work method or operating technique that the manufacturer does not specifically recommend, you must satisfy yourself that it is safe for you and others.You must also make sure that the procedure, work method or operating technique that you choose does not render the transfer switch unsafe.

Only qualified electricians should attempt installation of this system, which must strictly comply with applicable codes, standards and regulations.
WARNING
Failure to properly ground transfer switch can result in electrocution.
•DO NOT touch bare wires or receptacles.
•DO NOT use transfer switch with worn, frayed, bare or otherwise damaged wiring.
•DO NOT handle electrical cords while standing in water, while barefoot, or while hands or feet are wet.
•If you must work around a unit while it is operating, stand on an insulated dry surface to reduce shock hazard.
•DO NOT allow unqualified persons or children to operate or service transfer switch.
•In case of an accident caused by electrical shock, immediately shut down the source of electrical power and contact the local authorities. Avoid direct contact with the victim.
CAUTION
Improper treatment of transfer switch can damage it and shorten its life.
•Use transfer switch only for intended uses.
•If you have questions about intended use, ask dealer or contact Briggs and Stratton Power Products.
•DO NOT expose transfer switch to excessive moisture, dust, dirt, or corrosive vapors.

Briggs & Stratton Power Products Manual Transfer Switch
Installation and Owner’s Manual
INTRODUCTION
Thank you for your purchase of this Briggs & Stratton Power Products Manual Transfer Switch.This product is intended for use with Briggs & Stratton Home Standby Generator sets ONLY.This is an optional home standby system which provides an alternate source of electric power and to serve loads such as heating, refrigeration systems, and communication systems that, when stopped during any power outage, could cause discomfort or the like.This product DOES NOT qualify for emergency standby as defined by NFPA 70 (NEC).
Briggs and Stratton Power Products (BSPP) has made every effort to provide for a safe, streamlined and cost-effective installation. Each installation is unique; it is impossible for BSPP to know and advise of all conceivable procedures and methods by which installation might be performed, nor the potential hazards associated with those methods. For these reasons,
Only licensed electrical contractors should install transfer switches. Installations must strictly comply with all applicable federal, state and local codes, standards and regulations.
Your BSPP Transfer Switch is supplied with this combined “Installation and Owner’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.
To arrange for proper installation, contact the store at which you purchased your BSPP 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.
For the Installing Dealer/Contractor
Check federal, state and local codes for questions on installation.
If you need more information about the transfer switch, call 1-800-743-4115, between 8:00 AM and 5:00 PM CT.
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.
For the Home or Business 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.
Installer Responsibilities
•Read and observe the safety rules.
•Read and follow the instructions given in this manual.
•Check federal, state and local codes.

Briggs & Stratton Power Products Manual Transfer Switch
Installation and Owner’s Manual
Equipment Description
These transfer switches are intended to operate compatible electrical loads of normal residential installations.The load is connected either to utility power (normal) or home standby power (emergency).
Mounting Dimensions
Figure 1 depicts the physical size and mounting hole locations of the manual transfer switch enclosure.The transfer switch enclosure is commonly secured through the predrilled holes, as shown.
These manual transfer switches are equipped with two circuit breakers (“GENERATOR SUPPLY” and “UTILITY SUPPLY”) and a mechanical interlock.The “GENERATOR SUPPLY” circuit breaker provides power from the generator to the load devices wired to the manual transfer switch.The “UTILITY SUPPLY” circuit breaker provides utility power from the distribution panel to the load devices wired to the manual 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.These manual transfer switches 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 affect on the generator or transfer switch components.When utility power is restored, follow the instructions in the section “System Operation”.

ESSENTIAL CIRCUIT
Ensure that the total of the selected load circuits fed by this transfer switch are within the generator's rated capacity.
ISOLATION
Essential electrical loads are loads that will be powered by the Standby Generator System. Essential loads are grouped together and wired into the transfer switch.
TO THE INSTALLER: Consult with Standby Generator System owner(s) to discuss their “Selection of Essential Circuits”, described in owner’s manual.
Figure 2 — Typical System Diagram with Essential Circuits
The following requirements apply to this type of isolation system:
•The Manual Transfer Switch is installed after the main distribution panel.
•The Manual Transfer Switch has a load rating of 60 Amps. This is the maximum load rating of the essential loads.
All wiring must conform to national, state and local codes.
The illustration in Figure 2 depicts the Standby Generator System and assumes the utility is supplying 120/240 Volt, single-phase electrical service.
