>Let's hear. I want to know all about how to steal $2 of electricity >per month with complex devices.
 
Sounds like those generators. For about a million bucks they will feed your house electricity for about seven years. Divide it up, do you pay $11K a month for electricity ?
 
If they got a device for like two grand that saves you two bucks a month it takes years for it to be cost effective. And that is if it works. Power companies put millions to make sure it doesn't.
 
What I said about pulsing very fast and hard, that can fool an old mechanical meter because of what is known as mass. With totally electronic ones you have to pull the juice so fast it clips, like an audio amp.
 
Still, electricity is relatively cheap. Try making your own. Get a Generac, now look at its fuel consumption and you will see it costs a hell of alot more.
 
So my question just became - Why bother ?

>Is the green sticker some sort of local code inspector approval?
Yeah, the green sticker is what WA state uses to show that the
electrical work has passed inspection. It is filled out by the
inspector with the date and so on.
