10 Circuit Manual Transfer Switch Kit
(consisting of switch, inlet box, cordset with 20A & 30A plugs, wire connectors)
Pro/Tran by Reliance Controls

Easy to install and operate, connects portable generator to residential load center.  Allows manual transfer of individual loads to prevent overloading generator.   Each individual circuit can be transferred separately and only as needed.   Now required by Article 702.6 of the 2002 National Electric Code to prevent inadvertent backfeeding of electric power from generator into utility system which can be a safety hazard.

30A Power Inlet Box

For installations where the building electrical panel is located indoors and generator is located outdoors.  Eliminates need for open window or door for generator cord.  Raintight NEMA 3R box with four combination 1/2" and 3/4" knockouts: one each side, bottom and back.  Twist lock male L1430P power inlet receptacle for cable connection to generator, 7500 watt maximum.  UL listed and CSA certified.

    * Compact size
    * Inlet plug is on front of box for easy cable connection

Note that this box is suitable for wet locations when the cover is closed and cable is NOT plugged in.  This is usually not a problem since portable generators should not be operated outside in bad weather anyway.
