Three-phase house wiring. Okay, most of us take electricity for granted. We walk into the house; we flip a switch, the light comes on, or you know, if the switch goes bad we replace the switch if we're handy. We don't think much about the nature of the electricity that's coming into the house. So, a discussion of three-phase wiring requires a basic understanding on two levels. One is that three-phase wiring is what's coming into your house, and it's generally converted into single phase which is what we know of as wall circuits that you plug your lights into. In the case of single-phase you've got, because there is only one phase you've got fluctuations of voltage constantly. Now, in three-phase wiring you have, the three phases of electricity are cycling, how best to explain this, at at a rate that keeps the voltage constant, let's just put it that way, and there's certain appliances that require this. Most electric motors you have to run off a three-phase because it it needs a constant voltage supply, so that uses a high-powered, any kind of a high-powered electric motor. It may be a, may be your, you might have a built in pool in the backyard. You probably have a three-phase system that drives the pool pump. Large central air conditioning and heating units typically use three-phase. It's it's more common in commercial or industrial buildings because of the needs that they have, and there's always heavy load items that use three-phase power in those places, but even in a house. A lot of, a lot of homes in Europe use three-phase power for their electric stoves, and I believe if I'm not mistaken, refrigerators as well. So basically, think of of three-phase wiring in the home as continuous voltage regulating power that stays constant.
