NOTE TO INSTALLER: Please leave this guide with the consumer for future reference. READ THIS MANUAL IN ITS ENTIRETY BEFORE ATTEMPTING TO INSTALL THIS EQUIPMENT.
WARNING: 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 OUTDOORS only. Our transfer
switches are UL listed to UL 1008 and meet the criteria of National Electrical code Article 702.6 for Optional Standby Systems. CAUTION: 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 generator. No appliance should have an amperage rating that exceeds the individual breaker rating in the transfer switch (20 or 30 amps). CALIFORNIA PROPOSITION 65

Power Cord to connect generator to transfer switch.
•
White, green, black and red THHN or MTW wire, 10 AWG, 300V rated (if breaker configuration is modified or expanded).
•
Switched Neutral Kit (SNK or Generac model 6297). If your portable generator has the neutral bonded to the frame of the generator AND 240V "full-power"
•
receptacle is GFCI protected, you will need to install a SNK accessory with your transfer switch to avoid nuisance tripping of the GFCI breaker on the generator.
NOTE ON NEUTRAL BONDED GENERATORS: Some portable generators are intended for use on jobsites and are subject to OSHA regulations for GFCI protection on all
receptacles. These "contractor grade" generators have their neutral wire bonded to the ground wire to pass OSHA inspection. When connected to a transfer switch this may
cause nuisance tripping of the generator GFCI breaker. When using a neutral bonded generator to power a house or building through a transfer switch consult the manufacturer of the generator (local
authorized service dealer) to determine if the neutral-ground bond wire on the generator can be removed without voiding the warranty. If it can be removed then no modifications to the transfer switch
installation are needed. If the neutral-ground bond cannot be removed, or voids the generator warranty, you MUST install a Switched Neutral Kit (SNK, Model 6297) accessory with your transfer
switch. NOTE: Removal of the neutral-ground bond should be performed only by an authorized generator service dealer or qualified electrician. If the neutral bond is removed the generator will no
longer pass OSHA inspection on job sites.
