Good deal. I picked up a Mira Go for £56 at B&Q yesterday but they are very limited stock.

....picked up 5 this afternoon Cheers op!

This requires 10mm cable I would imagine.

6mm would be fine fore 9.5kw
anything higher then yes you would typically

I've got a long run of 6mm though which runs from the back of the house up the wall over and around the gutter fascia on the roof and to the front of the house where the consumer unit is, must be about 60 feet, would that have any detrimental effect such as voltage drop, amp load and overheating of the cable at that length using 9.5Kw?

In short, yes. There is a spec to follow dependant on run / cable angle/ surrounding materials etc... all in 17th ed. If your not sure what your doing don't mess imo - the shower and the cooker are to be treated with respect.

here are some cable size calculators for those of you trying to figure out what size cable to use:

bbowner.co.uk/vol…tml

just a simple tip, to avoid 10mm cable which is a pain to use and is expensive,

you can use more than one cable in the same run,

ie. if you have 6mm cable already, run another 6mm alongside it or 4mm or 2x 2.5mm which ever you need.

Not a good idea to run ordinary T&E outside if that's what you're doing - it will degrade due to UV exposure.

Fishmaster , the cable you have running over the gutters etc will be fine , you could actually run all your other household stuff from this cable and the high load will cause the cable to overheat slightly but that would keep your roof nice and warm through the winter

I think he's just illustrating the point that you can't just say that 6mm is fine without taking into account the length of run.

I think that's a really bad idea. What happens if one cable becomes disconnected or develops a bad connection? Then your remaining cable(s) would be seriously overloaded. What if someone in the future who's even more inept doesn't see the why you have put in two cables and removes one of them? I very much doubt that such an installation would meet wiring regulations. Please do it properly.

Yes of course, but in the process has revealed some bad practice.

that's the problem , you doubt because you don`t know.

No that's not the problem - the problem is you doing something so clearly unorthodox, for which I have pointed out a risk. Me not being certain it's against wiring regulations is the least of the issues - it would be your responsibility to ensure it complied before you did it.

The current comes out at roughly 41 amps for that power rating. 6mm wouldn't be sufficient unless just clipped direct which it won't be. Odds are it passes through an insulated wall/insulated partition wall or possibly insulated loft space in which case the current carrying capacity is below 41 amps.

Go with 10mm. Can't go wrong then, as going wrong could mean a melted cable at best, a house fire at worst!
