What is the point in 2 or 3 phase ovens and hobs? And why sell them for the domestic market? Is it just to confuse average DIYers? Shouldnt they come with warning labels stating "warning 415v"?
I have seen 3 phase commercial ovens. Why 3 phase? Why not wire them to a 32/40A MCB on one phase? It would certainly be easier to wire.
Do 3 phase 250A (each phase) supplies exist? I overheard an electrician at a shop i was at which is having a refit, saying something about a 250 something or other! Its a big shop with a big plant unit with loads of compressors for fridges and freezers and 3 big coldrooms, loads of lights, electric fan heaters, a couple of 3 phase ovens, possibly air conditioning in the near future, would this warrant such a supply?
