Hi Michael, do you have a view on going 3 phase 400v? I am Dutch and our grid is 220v but we only have a 16a fuse box which implies we can’t use a heatin element above c. 3700 watt. That is unless we go three phase which gives us 400v implying we could go above 10kw (which would be ridiculous for a 15 g kettle but in theory we could, you get my point I guess).

Question is how will this change the controller parts list and of course the wiring. Many thanks, I am in planning phase now as our new house is currently being built so I have some room/flexibility to let my electricien work his magic.
