the power rating of the shower you buy will be printed on the box and also shown in the sales brochure and installation instructions. RF means that he can't see what sort of shower you have got.

domestic lighting circuits are almost invariably fused at 6A, though there is often one lighting circuit for each floor of the house.

harryc, your house will need exactly 67.5 amps.

Outstanding, thats what I made it too!

But you both did the calculation at 240V.

Use the correct Uo of 230V and you'll see that Harry needs 70.4A.

I can't believe you made such a basic mistake ...

Ban, it's not like you to be inaccurate.

The true figure is 70.35627A.

Oh Dear! Oh Dear! Oh Dear!

Amps, Volts & Watts are all dependent variables

And if Ohm's Law is applied

V= IxR

So if V is reduced from 240 to 230 then current will decrease.

to 64.8725 A (approximately)

Hey guys... I think DESL needs a new sarcasm detector, the old one must have overloaded and burnt out
