This is a potentially very dangerous project. It involves working with AC house power (120/240V) that if not treated with the proper care can cause bodily injury and/or destruction of property.

The current transformer outputs 1V signal when it gets 20A current through it. With around 200mA, you should get about 10 mV AC at the current transformer output. Measure it with sensitive multimeter AC measuring range – hopefully your multimeter can measure this low AC voltages.

I don’t know how to measure Current and Voltage with load and unloaded. I have inserted 40W lamp probe into CT. How do i test using DMM? can you pls tell in detail?

of this sector do not notice this. You must proceed your writing.
I am confident, you’ve a great readers’ base already!
