InstallationandOperatingInstructions 1
Generac® transfer switches should be installed by a professional electrician familiar with electrical wiring and codes, and
experienced in working with generators. Generac accepts no responsibility for accidents, damages or personal injury
caused by incorrect installation. This transfer switch is intended for surface mounting INDOORS only. Our transfer
switches are UL listed to UL 1008 and meet the criteria of National Electrical code Article 702.6 for Optional Standby Sys-
tems.
If using the generator and transfer switch for larger appliances, such as electric water heaters, clothes dryers, electric
ranges and small air conditioners, check the labels on the appliances to be sure they do NOT exceed the rating of the gen-
erator. No appliance should have an amperage rating that exceeds the individual breaker rating in the transfer switch (20
or 30 amps).
INTRODUCTION: Thank you for purchasing a Generac Transfer Switch to safely connect a portable generator to the load
center in your home or business (single phase only) for standby power applications. Product features include:
•Generator and Utility feeds mechanically interlocked to prevent dangerous utility or
generator back feeding – thereby avoiding property damage and serious injury to
electrical workers.
•Pre-wired for fast, easy connection to the load center.
•Each model can be expanded up to 10 circuits using standard interchangeable type
circuit breakers. See Step 2, Section II.
•Accommodates GFCI and Arc-Fault breakers to meet the latest NEC requirements.
•Dual wattmeters help you monitor and balance the loads on your generator, pro-
longing generator life.
•Safe generator connection – Install the Power Inlet Box in a convenient location
outside for a quick cord connection to your generator.
•Surface mount enclosure indoors. Not approved for outdoor installation.
•Accepts Switched Neutral Kit (model 6297) for neutral bonded generators.
