I have a 45A breaker at the CU and 6mm2 cable running around 18m. The 18m is the total run length to the unit. Obviously there is a DP 45A switch in the circuit.
I have read on one table (http://www.tlc-direct.co.uk/Technical/DataSheets/Sadia/Carousel.pdf ) - page 9 I can use up to a 10.8 Kw
But in I have also read in a DIY Guide that "45A feeds up to 8KW". Maybe they were playing it safe as they did not state a cable length?
Any guidelines please? I would like to fit at least a 9.5KW but of course dont want to risk burning down the house.
