Hello,
I need some way to monitor when a 220VAC circuit is in use. This circuit powers an outdoor radiant heater, which according to the specs, draws 12 AMPS. The header has two states, on and off, therefore the load should be consistent when the heater is on.
My theory is to install a torroidal CT in the circuit which powers the heater (over one of the conductors), and drive an LED from this CT. I have never worked with CTs before, and I do not know how to select the correct one. Also, I don't know if I will need any other components in this circuit (diodes, resistors, etc...).
The purpose of this little project is to have a reminder light (LED) inside my home to alert me if the heater was accidentally left on.
Thanks in advance of any help provided.
Mike
