[QUOTE="Phoenix, post: 428900, member: 8133"] My gut feeling is that a single 50A load that's on for a long time frame is pushing the limits for anything that is intended as a domestic board. I think for me it would have to be one of the two answers that has come up in the thread in various ways: A) Fit a commericial type A board, such as schneider. B) Use your preferred brand of consumer unit (such as SBS compact RCBO based board) and sit a separate switchfuse for the 12kw of water heating. At one time I would have suggested a wylex 160CM, as they have twin terminal screws, plus you can loop 25mm² tails in and out of the supply side so avoids henley blocks. However they have replaced it for Amd3 (why? - it was mainly metal anyway, plus the plastics in the standard range never did go all drippy when hot!) The replacement I think still features twin terminal screws but you cant loop in and out [/QUOTE]
