Hi all
I have a few questions that hopefully someone will be able to clear up….
First off:
Is my shower 10.8kw? On the box it says 10.8kw for 240v, but then in slightly small writing it say 9.9kw at 230v.
Now I know UK supply rms is 230v so maybe that answers my own question but…. why? Mira are confusing me slightly by advertising it as 10.8kw when quite clearly, it can never be!
My next question is probably a bit trickier - it's to do with cable size and length. I spoken to a good handful of electricians and an even healthier handful of 'DIY know-it-alls' at work and have had slightly different answers of each. I've also done a lot of interenet searching and found nothing definitive. Sooooooooo……..
Is a 10mm cable sufficient for my 9.9kw/10.8kw (?) shower?
I know there are lots of factors to consider here:
- Cable length
- routing
- etc
So any advice would be great. At the moment my set-up is this:
(And this is going to create some controversy I know!)
I'm running a 10mm cable from the consumer unit which has a 45amp circuit breaker. The consumer unit is in the attached garage and the cable runs along the garage, through the house wall, under the bath (I know!!), up into the loft, into the pull chord switch, and then back down again into the shower.
Overall I'm using 17m of cable with one join (two if you count the pull chord switch).
Before I connect it all up though, anyone who can be bothered reading all this is more than welcome to point out any glaring shodiness! I welcome the feedback because I'm no expert.
I know the underlying theme is "Get an electrician in", my problem with that is I've so much conflicting advice from qualified electricians, it seems to me to be whatever that particular electrician feels like.
Where are the hard and fast rules?
Cheers for the advice.
