As I said on another thread recently...

http://talk.electricianforum.co.uk/topic/23507-advise-needed/

IMHO installing an electric shower is not a DIY job...

Your post confirms this to be true...

The correct sequence of DEAD TESTS prior to enrgising the unit would have prevented this fault...

that is why competent electricians use the correct test equipment...

We don't just by the test gear as a hobby interest...

it is to ensure the safety of all electrical alterations done!

You have probably wasted  more time and money swapping unnecessary items...

than had you followed good wiring practice as per the guidance in BS7671 would have prevented your fault.

p.s.

RCD's are rated in miliamps not amps...

you do not have a 63A RCD..

As is always the case the person who considers themselves to be  "Highly competent"..

is a gnats whisker away from being an electrical novice working outside of there abilities..

Get someone with the correct test equipment to come and test the cable for you....

then start from whatever conclusions these tests come to...

You should not simply joins some wires then switch on to see if something works!

Very dodgy practice!!!

p.p.s..

You may have contravened building regs as well dependant upon which part of the country you are in.

Dont like to wee on anyones bonfire but the RCD may be rated at 63A and 30ma IE builders/shower supply consumer unit as marketed by the likes of tlc etc.  I agree a shower installation is not a DIY job and should have been tested correctly before and after energisation.

The OP is asking for help to find out what is wrong, surely this is better than fitting a bigger MCB or just doing without it.

Obviously the money I spend on Part P registration is completely wasted. No deterent against Doing it Yourself.

Obviously ALL RCDs have a maximum load rating that the switch contacts are designed to break...

(nothing to do with builders or TLC!!!)..

But just referring to this figure (as the op did) is no use at all without the MORE IMPORTANT tripping current...

10ma/30ma/100ma etc..

What value do you put on your certificates for RCD rated operating current ?   63A  / 80A ?

Or the ma value!!!

The point being, that from the post clearly the OP is NOT as Highly competent as he tought...

and has little or no idea about the point or the important rating value of the RCD...

Rated tripping current..

Or about basic dead tests!!

Could be that in the process if screwing back the isolator the cables are crushed and shorting out ?

Still I'd suggest that the OP gets a competent electrician in who will prevent the OP from highly competently injuring himself.

What peeeeevs me off about this sort of poster is he didnt even come back to view replies. He probably posted on numerous sites or spotted his mistake.

homebase are doing a 9kw triton (something) for £89.99 this weekend only...

Just saying....

now how do I connect this to an old wylex board and do homebase sell 40a fuse wire?
