®
Manual Transfer Switch designed 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 interchangeable type
circuit breakers – so as your needs change, just expand it!
•
Accommodates GFCI and Arc-Fault breakers to meet the latest NEC
requirements.
•
Dual wattmeters are provided to help you monitor and balance the loads on
your generator, prolonging generator life
•
Flexible generator connections – Use the Power Inlet for a quick cord
connection to your generator, or ask your contractor to hardwire your
generator connection.
•
Surface or Flush Mounting (with flush mounting plate sold separately).
Warning: Gen/Tran transfer switches should be installed by a professional electrician familiar with electrical wiring and codes, and
experienced in working with generators. Gen/Tran accepts no responsibility for accidents, damages or personal injury caused by
incorrect installation. These transfer switches are intended for surface mounting INDOORS only. GenTran 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 (20 or 30 amps).
