With a house which is only 220 single phase you won’t really save any money.
You really can’t get a huge imbalance.
Now at the shop we have 3 phase, so 3 load lines, red, black and blue.
So if you have a couple of 220 single phase refrigeration unit hooked up to the same lines, so black and red, you’ll have an imbalance of power on the blue line.
So you try to get a couple of heavy load 120v items on the blue line to compensate.
Mind you for each red, black and blue line (or each of the 3 phases) you have 1 neutral. You have to be careful not to overload the neutral line and need to only switch the lines between the 3 phases, between the shared neutral. So you can’t have red black and blue hooked up to the same phase, because you could have to much power combing back on the neutral which could be at a higher amp value than the wire is rated for and start a fire.
Honestly I’m not sure if I’m accurate about all this, but when I told an electrician friend I was going to balance my panel, this is what he suggested. He also didn’t think I’d save money. But my thought was if you can reduce the amount of money wasted on the neutral line, up you’d be pulling in less power on the load phases. It worked, but that panel was really out of balance, like 98 amp on two phases and 20 amp on the third. So a lot of power went on the neutral, sometimes up to 60 amps.
The hardest part was getting the individual line loads. See back then all I had was a volt meter that I periodically looked at, now you can likely buy a blue tooth cell phone one that would give you a 12 hour graph or something, lol.
I'm so far from being knowledgable with anything electrical lol.. What you say makes sense though.
I really wish when I was younger I took some eletroncics classes in high school. They only offered one course in gr 11 or 12.. thats it. and I didn't take it, I chose physics instead.
mechanical stuff was sort of taught to me when I was younger and mechanical stuff just makes sense to me. I don't have the basic background knowledge in electricty to really figure out stuff that your saying. Wish it was something I learned more growing up.
