What is the device that trips (what is written on it, does it have a test button)?
What rating is the shower?
Has anything been changed recently?

Flameport,
Many thanks for the reply
Nothing has been changed recently and it has been working fine for the last three years, I will answer the rest of your questions when I have the time to check both the shower and the consumer unit.

The circuit breaker is 32A square D, an old black one
The shower cable is 10mm
The shower is quatronic 9.5 KW
I understand that the recommended circuit breaker for 9.5 KW is 40A; however this has been working for the last three years without any problem, why it is tripping now?
I have also noticed that the wire is discoloured (it is not as bright as the other wires in the consumer unit) at the connection point to the breaker, any idea why? Is it heated?

that breaker has been running over capacity for 3 years, it is prob tired.
The solution is likely to be:
Cut back the cable to remove the damaged/overheated section
Replace the circuit breaker with one of the correct rating for the cable & shower.
A 40A circuit breaker is likely to be the correct option, but the cable size, length and installation method must be checked first.

Dear All,
Many thanks for your input.
Skenk,
I now it is 10mm2 as the breaker next to it is also 32A and connected to the cooker cable which is slightly thinner. I also followed it all the way to isolating switch then the shower.
I will try my local electrical merchants on Tuesday for 40A square D breaker and do what flameport suggested. In case I can find it as it is an old black breaker, any idea where I can get hold of one?
