In my camper I have standard 3 wire power coming in. 2 are 120vac and 1 neutral. Since the wires feed separate sides of the circuit breaker box with the neutral being common to both.
Can I place 1 current monitor coil around the neutral wire and get the total current used in both 120vac lines since it is the common "return" for both 120vac feeds to my circuit breaker box.
My desire is to get total power consumption using only 1 coil. As most 220V appliances simply split power and supply 2 - 120vac lines in the dryer to balance the load. i.e. a dryer separates the power... 1 side supplies 120vac to the motor, the other 120vac to the heating element.
Since both sides of the circuit breaker box share the common neutral wouldn't the current monitor show the total amperage of both sides of the box using 1 current coil?
