[QUOTE="phil d, post: 478194, member: 27126"] Did you know that you can actually run an immersion heater on a piece of 1.5 t&e? I only mention this because if you look at the current carrying capacity of that particular cable, it's suitable. What it doesn't tell you is over what length, you appear to be getting information from somewhere, but are not getting it all, and consequentially I fear your project will end in tears! Sorry to sound so brutal but that's how it is, when we size a cable we work out a number of factors, not just the table that gives the maximum current carrying capacity to arrive at the correct cable, quite often to the unskilled bloke it looks like we've massively oversized it, we haven't, it may be down to length of run, or thermal effects, or any nmber of variables. A mate of mine got called to a job, the guy wanted a single socket and a light in his garage and had done it himself, it looked ok, everything wired as it should, however when he tried to run a small cement mixer it wouldn't have it. he couldn't understand why, he'd used 2.5swa which he'd read was good for 27amps, not at the 110 meter length of run that he had it wasn't.
