Calculator for cable load

[Vicario]

I keep seeing references here to a way of calculating what load a cable can safely carry under different circumstances. Can anyone point me to a link please? I'm interested to know if a fairly short 6mm cable run (6m) will be OK for a 9.8kw electric shower.

It's all on the link, calculator index area, volt drop

Voltage drop wise it'll be fine, the issue is what installation method is used - if it's e.g. clipped direct then it will cope, if it's run above a plasterboard ceiling, you'll need 10 (as the calculator will tell you)...

Thanks. Very useful. It's a pity that the lowest ambient temperature they use is 25C, as very little of this cable run will be in the loft.
