After all that are you saying that you don't have 10mm² cable?mega_kas said:I will stick with the slightly overloaded 32a MCB, 6mm cable and 8.5kw shower.
This is not a competent premise - engage an electrician now.After all - this house has had an 8kw shower with the same circuit for a couple of years so it should be OK.
And if the house catches fire, how much redesign will you do then?If it does trip the MCB then I will do some redisgn and update of the circuit.
Softus, the OP said this a while back. Read the one with the pictures, or just before.Softus said:After all that are you saying that you don't have 10mm² cable?mega_kas said:I will stick with the slightly overloaded 32a MCB, 6mm cable and 8.5kw shower.
...is outrageous. I would say if he's comfortable with not knowing the derated capacity of the cable then the tools should be torn from his unqualified fingers. Here's another appalling example:Crafty said:Yes. 6mm is rated at 47 amps optimum, but I cant advocate such a gamble when you dont know the route of the cable. If you're comfortable with it, then do it.

Are you being deliberately obtuse? The risk to the cable is determined by its ability to cool itself, which is determined by what it comes into contact with and what insulation might be around it. If you don't know what surrounds the cable, then you don't what the risk is. If you don't know what the risk is, then you shouldn't be doing it. If you do it anyway, without knowing what the risk is, then don't be surprised if you wake up in hospital to be told that your family is in the morgue.Softus - so if I had a 7.5kw shower my house would be Ok but if I use a 8.5kw shower my house will definately catch on fire?
This is another indication that you don't understand then whether or not the breaker is correctly sized is [largely] independent of determining whether or not the cable is correctly sized.If you can take a minute to read the thread you'll see that I recognised that my set up isn't ideal but as crafty says - if the shower draws too much current it will trip the circuit breaker.
You're not at all sure - you're just hoping for the best without understanding, and you're clinging onto some poor advice from someone who agrees with you.I'm pretty sure that this will prevent the house burning down
WTF does post count have to do with being right or wrong, and safe or dangerous?...but then I'm not an electrician and don't have a post cout in the 10,0000s
Watch it Crafty - I have no problem with being criticised when it's justified, and as a case in point my apology for lack of reading has crossed with your jibe, but be very careful when you're advising people who don't understand how to determine cable current carrying capacities.Crafty said:mega_kas - just ignore Softus he can be a bit brutal sometimes. Especially when he doesn't have all the info or just cant be bothered to read it.
