What is Split-Phase Power? – Sense Blog

North American homes are not wired up with a single live wire, but two. The difference between them is that when one is pushing, the other is pulling, and vice-versa. The “normal” appliances and outlets in a house are divided amongst the two live wires, and all are connected to neutral. Because the voltage difference between a single live wire and neutral is alternating with a magnitude of 120V, appliances that run on 120V power can be connected to the neutral wire and either of the two live wires.

A gray morning for sure, much different than that morning some eighteen years ago. πŸ˜” Time goes by so quickly, two decades really isn’t a long time when you think about it. I just remember the blue skies, and the low humidity, perfect September weather that day. I remember the ugly orange walls in the classroom during my freshman year at college, and seeing the towers fall on television.πŸ“Ί Classes were canceled, I went up to Partridge Run WMA and went for a walk, as the skies were silent without planes flying above. ✈

New York was fun yesterday, but I’m glad to be back upstate today. πŸ™οΈ New York is as gritty as ever, lots of traffic and construction. I am glad I didn’t have to drive down there. New Jersey was the usual mess of suburban strip malls and speeding traffic on NJ 17.πŸš—

I’ve been reading a lot about delta and wye three phase power. πŸ”Œ It’s interesting to study power poles and see if they are carrying delta or wye or single phase power — as is common in rural areas like where my parents live. Power infrastructure is often very visible from the highway so you can study the wiring if you look at it.⚑ Electricity generation and distribution is often a story of compromise and choosing the best of option of many bad options.

Saturday doesn’t look that great, but Sunday will be warm, summer like with modest humidity. πŸ˜• Saturday, a chance of showers before 2pm. Mostly cloudy, with a high near 76.
