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. Our transfer
switches are UL listed to UL Standard 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. CALIFORNIA PROPOSITION 65 WARNING:
Engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects and other reproductive harm. This product may contain or emit chemicals
known to cause cancer, birth defects and other reproductive harm.
Thank you for purchasing a Generac Manual 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 Mains mechanically interlocked preventing utility or generator power back feed.
• Full branch circuit protection with Siemens
®
circuit breakers.
• 12 gauge High Corrosion-resistant aluminum cabinet.
• Ample ground and neutral termination positions for all branch circuits.
• Extra spaces for branch circuit breakers.
• Subfeed lugs provided to feed additional downstream panels or to expand beyond 16 circuits.
• Accepts a Switched Neutral Kit (Model 6297). See Note on Neutral Bonded Generators found above
Table 1.
Description:
This unit is a combination indoor/outdoor transfer switch and distribution panel.
It can be used as service entrance equipment for 200 Amp services. In addition
to being a transfer switch, this unit provides additional circuits for outdoor
applications such as air conditioner compressors, sewage lift pumps, boat
docks, outbuildings, garages, pump houses, barns and the like. These 200 amp
series models will accommodate 12 single pole circuits.
This transfer switch is made up of five basic elements:
1. 200 amp rated Utility Main Breaker
2. Generator Main Breaker
3. A 30 or 50 amp 125/250 volt inlet pre-wired to the generator breaker
4. A mechanical safety interlock that prevents both Mains from being
“ON” at the same time
5. A set of sub-feed lugs to handle cable up to 4/0 AWG to feed the
house Main panel.
Tools and Items Needed for Installation:
• 1/4" and 11/32 nut drivers
• Straight blade and Phillips screwdriver
• Large Allen wrench Set
• Electric drill
• Wire cutter/stripper
• Anchors and screws to mount switch to wall
• Power Cord to connect generator to switch
Compatible Circuit Breaker Types:
• 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
• Square D Series HOM (Homeline)
• GE Series THQL
CAUTION: If this transfer switch is used as the main service disconnect, it is imperative that all circuit breakers in the transfer switch AND the Main Load Center in the house
be turned OFF when running the system from the generator. Then, turn on only the breakers that the generator can handle at any one time. Check the generator “continuous”
wattage rating to determine the total wattage of connected load. It may be necessary as well as desirable to turn ON and OFF different loads/breakers as needed during an
actual power outage.
