Progressive Industries ADT-230 Cheater Box Retail: $79.00smkettner wrote:
Their "features" description is a little misleading, as it combines two single 120V circuits to give a 120/240V circuit.Features:
The Cheater Box plugs into and 30amp and a 20amp source on separate circuits to give user a 50amp output.
Will not operate on a GFCI circuit.
Designed for outdoor use.
The amperage at 240V is limited by the lowest amperage of the source 120V circuits. It's a NEMA 14-50R 50 Amp receptacle, rated for 50 Amps but it's connected to sources that supply less than 50 Amps. So it's a 50 Amp receptacle on effectively a 30, 20 or 15 Amp circuit depending on the source circuits you plug it in to.
This image shows the source plugs which helps to understand this little box better:
This Google search on part number "230-ADTP30" digs up more suppliers and a few reviews.
