In the input are both Wires positive or negative? How do we know which is positive or negative in the output and the input?
There is no polarity or positive and negative for AC power. There are 2 wires for 110VAC input and 2 for 12VAC output. As long as you don\'t mix up the input and output it should work no matter which 2 wires are connected.
