Just another one of these double check questions.
I've redone the sink and plumbing in my garage and bought a small inline heater so I can have a bit of warm water, or at least not Ice cold.
It's 4.4Kw (19.13Amps). The cable will either be armoured clipped direct or T&E run in plastic trunking onto brick based in what I've got lying around and into it's own 32amp MCB. I've got both in 2.5mm² but nothing bigger that's long enough. I've had a look online at cable ratings and 2.5mm² is good for either 23 or 27amps depending on which reference method I use (B or C)
For arguments sake let's say it draws 20 amps and my max is 23 amps, is this cutting it too close for the cable, is there a recommended safety margin like for a breaker? I realise for the amount of time it will be operating it will be fine but it doesn't mean I want it to be dodgy.
Speaking of breakers a type B should be sufficient for this type of load shouldn't it?
Thanks,
G
