I'm trying to help a friend with his Marley electric baseboard heater wiring. Heater is rated at 1500 watts,208/240 volt. He ran 12/2 wire with ground from the circuit breaker box (20 amp double pole breaker) to a Mears M602W thermostat. From the thermostat he ran the 12/2 to the heater. My question is the thermostat has (beside the ground) two black wires and two red wires. How should the 12/2 wire be connected to the thermostat? Does the 12/2 HOT wire (black) connect to the red or black wires of the thermostat, and the white (neutral) connect to the other pair?

Now to make it more interesting how does the 12/2 connect at the heater itself? I believe he has black and red wires there also, but can't remember if it is a single or double black and red wires. [img]/forums/images/icons/confused.gif[/img] Thank you in advance. Stanley
