While researching if summing two 110 legs of a 220 V circuit will give me the value I want I discovered RMS voltage. This is why I love doing projects from scratch myself, I learn a crap load in areas I know very little about.
Anyways when the kids are napping I'm going to give RMS a try and see if I can get that math working out. Right now I have no exact mains voltage reading so I'll have to hardcode based on what the wattmeter reads to calculate my wattage used.
