Some older houses (< 1960, mostly early 20th century) have had 2 phase 127v systems in place in the Netherlands (either with or without neutral). They have gradually been replaced by 240v.

Maybe this is the reason people still talk about 2 phase systems.

So, like a mini Japan? What do people do when buying appliances? Are the plugs different? Do you use 127V or 254V for appliances and light bulbs?

I think it’s mostly been phased out by now, the few places (historic city centers) that have it will bridge the 2 phases to get a single phase of 220V. I think 127V equipment hasn’t been sold in like 20+ years

Phased out haha! :-D
