I have wall heaters in my house that are about 2' X 3' in size and each have knobs that adjust the temperture, and buttons that push in for heat, fan only, and off. These heaters use a coil, looks like a long spring, that heats up and the fan pulls air across it. When I go to clean the heaters, I turn the heater on, then I find the breaker in the box that goes to the heater and turn it off, then the heater stops. I remove the face cover and then when I try to remove the wires from the control switch, I still get a small shock. If I touch the coil, I get a small shock. I can't understand how current is still in this unit. I put a meter on a couple of the wires and got around 70 to 80 volts. This is an older house and the heaters are old also, but work well. Thanks for any advice on how to get the current off these heaters, short of cutting the entire electric from the house.

A few questions:
Is this 220 volts (in the U.S.)?
Is there a ground wire?
Does the 70 - 80 volts reduce/go away if you short it to ground/frame for a few seconds? (Maybe the fan has a start capacitor.)
Are there multiple heaters or other devices on the circuit? That is, when you trip the breaker do other things shut off as well?

I really don't know if the heaters are 220 or not. Without disconnecting the control switch, I can't get to the main wires that run to the heater. There might be other outlets on the line but there is only one heater. The breaker that turns the heater off is a regular 110 and not two for 220.
