Cable Size

[Michaelwgroves]

I need a cable for 10kW/44Amps Shower. 10M run

TLC Catalogue for T&E 6242Y recommends 10mm upto 53 Amps. Doncaster Cables online calc reckons 4mm.
Draka online calc agrees with TLC. Common sense also says 10mm.
What have I got wrong for Doncaster to suggest 4mm?

Thanks
Michael

Hi Mate

The cable calc on the TLC calculator [Voltage Drop Calculator]gives a cable size of 10mm

If an online calc is that blatantly wrong, then this could be disastrous for all the DIY'ers out there who haven't got a clue (and some so-called electricians).

which is why DIY should be limited to replacement of accessories and gardening.

Many people's maths skills aren't that great either!

Okay, latest update. The Doncaster cable calc is based on cable type BS5467 (Armoured), not T&E 6242Y as I first thought. It's in the small print. That said, they are correct.
I bet there it not many DIY'ers that will spot that subtle difference, or even electricians!
Be warned.
