10.5Kw shower 45A or 50A MCB

Can you get 50A pull cord or douple pole switches.

Not come across one but you could probably use an incomer mounted in a din rail box of some kind.

Any advice greatly appreciated as to what size mcb to
use.

For what rating of shower?

 

Doh! It's in the title!

 

Well 10500w / 230 is 46a so I would use a 50. There was a post about this a while ago and I pointed out that, although the mcb will likely not trip at 46a*, it is not good practice to run your mcbs at or near their nominal rating.

*I think the trip rating of mcb's is 1.45 the nominal = 66a...

Use a 50 amp B Type.

Use a 50 amp B Type and RCD protect. Due to the nature of your post are you competent to carry out the job? Maybe best for a sparks to carry out the work.

If you suspect that, then why didn't you say so in your first reply?

And more to the point, why are you offering advice on the MCB size when you have no idea of the cable size?

Mr Kangoo, formerly known as 'Ace Leccie', does consider himself to be competent. Moreover, he apparantly holds a very dim view of unregistered electricians, operating on his manor. . . . .

Well equally he did not ask about volt drop, max Zs, cable routing, any correction factors, mutually detrimental affects, nature of supply characteristics...blah blah.

 

Yes.

One such that Ib <= In <= Iz

 

Now that's what I call a succinct answer.

No, and nor did you.

The fact remains that both you and JP advised on the MCB size having no regard to the size of cable. JP did at least help out regarding the 50-Amp switch though.

So stop wriggling. . . .

Ya boo sucks to you!

 

Marj, you have a pop at JP., then you mess with me and mr bo. Any trouble I destroy you electrically.

If he is competent then he knows the cable size doesn't he X. Due to the nature of his post thats why I asked if he was competent. You are still making yourself look a fool aren't you. Again I say you are a pathetic little has been.

Afternoon Mr Bertrand. That X is now so pathetic he doesn't even know whats going on. The chaps knows what he is doing? and I cannot find any reference to cable size questions. Waht we need is fresh people like Ant and the like on the forum, because X is losing credence with the peeps.

 

JP.

Piss off

Once again you miss the point ....

 

Well JP. you win every time so I can't see why they argue, and 2ndly all the threads are wind ups anyway, as you can see by the title of this one!.

Likewise. Makes me think if you need to start putting disclaimers at the end of your posts. I say again that I question the chaps competence. If you don't like it then don't post replies to my answers and let in the field electricians question me. Sinewave springs to mind, he might disagree but he sure has not got your approach. It will not work with me. Thought you learnt your lesson by now.

 

Have looked around the site for an answer to this one
but to no avail.

Opinions seem to differ.

Thank you.

This man is competent. Where is there any reference to asking about cable size?
