GENERATOR SAFETY TRANSFER SWITCH KIT MODEL 6294

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 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 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).

Thank you for purchasing a Generac Transfer Switch Kit 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 to up to 10 circuits using standard interchangeable type circuit breakers. See Step 2, Section III.

Accommodates GFCI and Arc-Fault breakers to meet the latest NEC requirements.

Dual wattmeters help you monitor and balance the loads on your generator, prolonging generator life.

Safe generator connection – Install the Power Inlet Box in a convenience location outside for a quick cord connection to your generator.

Surface Mount enclosure indoors. Not approved for outdoor installation.

What is Included in this Carton:

Manual Transfer Switch with wire harness, conduit, fittings and wire connectors (6)

30 Amp Resin Power Inlet Box

10 Foot Power Cord with L14-30 male and female ends

Installation Manual and Warranty Registration card

Tools and Items Needed for Installation:

¼” nut driver, 2-1/8” hole saw (if flush mounting)

Screwdrivers, straight blade and Phillips

Electric drill, drill bits, wallboard saw

Wire cutter/stripper

Safety eye goggles

Anchors and screws to mount transfer switch to wall

New 60A 2-pole, 240V circuit breaker to install in main load center – should be same manufacturer as existing load center.

4 gauge building wire and conduit to connect between power inlet box and transfer switch

Optional Items for Installation:

Arc-fault, GFCI or Surge protection circuit breakers. If Arc-fault, GFCI or Surge protection circuit breakers are used as the branch circuit protector in the main load center, they MUST be used in the manual transfer switch. You may be able to re-use your existing AFCI, GFCI and Surge protection circuit breakers in the manual transfer switch. See list of compatible breakers below.

Wire, fittings and conduit to connect the Power Inlet Box to the transfer switch

White, green, black and red THHN or MTW wire, 10 AWG, 300V rated

Switched Neutral Kit (SNK). 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 therefore 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 on job sites, and when connected to a transfer switch, this may cause nuisance tripping of the generator GFCI breaker. If you’re using a neutral bonded generator to power a house or building through a transfer switch, then determine if the neutral bond wire on the generator can be disabled without voiding the warranty, preferably by a dealer or a qualified electrician. NOTE: After this action, the generator will no longer pass OSHA inspection on job sites. Consult the manufacturer of your generator to determine if the neutral bond can be removed. If it can be disabled, then no modifications to your transfer switch installation are needed. If the neutral bond cannot be disabled or voids the generator warranty, you must install a Switched Neutral Kit (SNK) accessory with your transfer switch.

Compatible Circuit Breakers:

Siemens/Murray QT, QPH, HQP, QPF (GFCI), QPHF, QFP, QE, QEH, QAF (Arc Fault), QP (Surge Protector)

Cutler-Hammer Series BD, BR, BQ, GFC

Challenger Type A, C, HAGF
