I've noticed we are getting a lot of 3kW kettles here with smaller flex now. Admittedly, that flex is very short and the boil time is very quick, so I guess they reckon it's okay. It is interesting though, to see what flex will cope with, particularly as the Brits are so obsessed with having 3amp fuses in plugs for lamp flex etc. If it's so bad having less (i.e a 16 amp mcb) protection, why aren't there more fires all around the globe where they don't have this protection? Just a thought....
