Split phase?
And that's why I didn't waste my time watching the video.Correct!
Peak to peak its 240V. UK is 480V peak to peak.
And that's why I didn't waste my time watching the video.
The UK grid is 3-phase. An installation can be supplied with a single phase or all three depending on power requirements.Does the UK supply both phases to a residential service?
Clickbait and a waste of time obviously.
Unless I'm misunderstanding, yes we receive AC voltage.Does the UK supply both phases to a residential service?
Wrong. Each phase in the UK is 240 V RMS or about 680 V peak-to-peak.Peak to peak its 240V. UK is 480V peak to peak.
How is it 680V? I'm clearly missing some understanding of this.Wrong. Each phase in the UK is 240 V RMS or about 680 V peak-to-peak.

The title of that video is misleading. The US grid is 120 Vrms between live and neutral/ground. If an unqualified single voltage is given when discussing the electricity grid, that's what it refers to, never anything else. Because of the low voltage, high-power devices are sometimes supplied with split phase to halve the current demand. Civilised countries use a higher per-phase voltage and three-phase supply for really demanding loads.I've watched some of his other videos. If you understand the way the grid works it's nothing new. But his videos aren't what I would call "click-bait". He takes technology and explains it in conversational way to people that may not be EEs.
240 V is the root-mean-square (RMS) voltage. The peaks are ±sqrt(2) times the RMS value, so the peak-to-peak voltage is 2 * sqrt(2) * 240 = 678.82 V.How is it 680V? I'm clearly missing some understanding of this.

Thanks, I've fixed it now.Your calculator is broken.
