For the Dutch perspective. Dutch grid operators consider 3X25A the default these days, but many older houses are indeed still only 1 phase (eg 1x35A).
There are mainly 2 categories for stoves, but I don’t think a 2 phase option exists: (source: just bought one)
1. ~7.4kW with a double group (4 pins) connection. That gives you 2x16A, but is still only one phase, just split over 2 fuses.
2. 10kW+ with a 3 phase connection (also 4 pins), in this case it actually is using 3 phases.
Dutch prices are regulated. The annual fee for a 3x25A connection is the same as for 1x40A. The next step at my grid operator (3x35A) is much more expensive.
- consp 7y agoSome 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 They have gradually been replaced by 240v.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.
- jacobush 7y agoSo, 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?
- hectormalot 7y agoI 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
- jacobush 7y agoPhased out haha! :-D
- stunt 7y ago3-phase is better future proof system. Electric stoves, dryers, oven, and soon EV chargers are everywhere.
- derfniw 7y agoActually I think the 2x16A should have a different phase per fuse. Otherwise you hit the max of your phase fuse when you put all 4 (assuming a somewhat standard one) heating plates to the max. In NL, assuming a somewhat modern setup, you have two sets of fuses: one per phase capped at the phase capacity ( commonly 25A), and then another fuse per group (usually: 16A).
