I realise that this is UK diy, but please bear with me
I need to know how to work out whether the following is viable or not.
My supply in Spain is 15A/3.5KW which can be updraded to 25A/5.7KW.
Do you think it is possible and safe to run an electric shower of around 6KW. If not what size shower could I run and also can you tell me how the figures are found
Many thanks
The figures for the protection are ( fuse or mcb ) are found by dividing the voltage by the power to give a figure in amps.For your 6KW shower a current of
25Amps would flow based on a 240 Volt supply. You would need a larger mcb than 25Amps in the UK showers are generally protected by a 40A mcb.You also need to consider the size of the cable and the length of the cable run.
Is it possible that this is the rating of her main fuse / branch circuit?
If this is the case then a very simple answer is available:
You can't run a 6kW shower on a 5.7kW supply nor, obviously, a 3.5kW supply.
I'd also suspect that even in Spain, 6kW isn't going to make a particularly hot / fast shower.
Hwyl!

I was thinking along these lines but I lost the thread! Now it's back I'll comment on it, ISTR someone else on here mentioning the Spanish electrics only having a 20A supply to the property. I think *any* electric heating is going to be a no-no.
