The wires from the breaker were: white black and ground. I connected the white to the red terminal in the heater and the black to the black and I also connected the ground as well. Then as I was at it I removed the Aube thermostat and replaced it with new Noma. The wall mounted electronic thermostats that blew were: the original Aube Model PB100-24083 and the second one was a Noma programmable electronic HTM611A. What would be the reason for them both blowing? Pb

With a red and black wire, it sounds like you have a 240VAC heater and myour bresker is 120VAC. If your neutral is connected to the ground bar, you may have shorted the 120VAc line. What does the data plate on the heater say.

You connected your 120v power from your breaker to the wrong connections in your heater. Sounds like you connected your wires to the thermostat side instead of the power side. Your electronic thermostats should be powered by low voltage, not 120volts.
