I have attached a schematic of a circuit which I want to build to monitor a 120V AC household (US) circuit. In the top section of the circuit I am using a voltage divider to monitor the voltage in the 120VAC circuit, and in the lower section of the circuit I am using a shunt resistor to measure the current in the 120VAC circuit.
I am somewhat nervous about directly tapping into a 120VAC circuit. Can someone review this to see if it looks good enough to try without frying my equipment and myself.
Also, for resistors and caps (especially the shunt), do I need to buy a certain type of resistor or cap to handle the larger 120VAC load. I am used to working on 5V DC circuits and similar and I am not sure if there is a certain type or Wattage that each component needs to handle the 120V circuit.
Thanks.
