GenTran 501210 User Manual

 

1 

:  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 or flush mounting INDOORS only. 
 

:  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 “GENERATOR MAIN” rating in the transfer switch.
