Hello All
Can any one provide non sarcastic suggestions as to why an 8.5kw shower has not tripped the 32amp mcb protecting that circuit?

Found this install in a domestic property. It seems to have been there for years, without out issue.

Thanks
DD
 
Like has been expressed, the trip curve characteristics explains why the 32amp doesn't trip but relative to design of the circuit we have a regulation that states small overloads for long periods should not be possible so anyone designing/altering this circuit should never have done that in the first place.
