its not tripping the one marked shower but the main one at the end

Oh dear.

What is it, an RCD, an RCBO, and MCB? This makes a difference to the reply. What exactly is written on it, or take a picture. Oh wait, this might help

Consumer unit

 

[aptsys]

Brilliant.

Which of the listed devices is tripping?

 

[Taylortwocities]

The consumer unit is the box on the wall. It has a whole load of things (trip switches) in it.
There are different types that do different things.
Which of these separate things is the one that trips? What is written on it?

 

[Paul finnigan]

The one that's on the end which I have been told is the upstairs main breaker the one marked shower isn't tripping on its own it's tripping all the upstairs

 

[Taylortwocities]

Sorry. Upstairs main breaker is not enough to identify it. From my picture above, surely you can match which on it is...…!
Ok, let us try and make it even easier
Is it a double or single width module?
Does it have a button on it marked test.
Does it have 30mA or 0.03A written on it?

 

[Paul finnigan]

It's the RCD that's tripping out sorry

 

[Taylortwocities]

Ah. Ok. It sounds like the heating element in the shower has failed.
Possibly will need a new heat exchanger, or replace the whole shower.

OK thanks very much for all your help and sorry for being a bit vague
