General Electric MCB - sensitivity?

[Dooby]

Bit stuck - anyone got more experience with boards like this?

Mate's ring main hasn't worked for ages - slow trip (like any time between 5 and 15 minutes) on the MCB (alone) with any load on it. Colleague reckons MCB is over sensitive and replace it to see.

Been checking out replacements that might fit this style, looks like it may be quite a faff - before I try it, is that a likely situation? All socket connections and cable seem sound so far. Or is there a more likely explanation?

Cheers

Why not just swap with the MCB beside it and see if the problem moves with the MCB or not.

Sockets kitchen 32 amp
Sockets living 32 amp

If I were you I'd swap the Kitchen socket circuit into faulty trip and vice versa just to prove your theory.

After that IR test, and see what the results are.

Oh FFS why am I such a moron. Only just back from work and just had a minute to think about it right now. So tired. THANKS! Will report back....

I can't bear to look at just how many of you figured this at exactly the same time whilst I got stuck at the 'archaic MCB' part

Don't worry about it for now, won't have time to go round and try a switch about and bit of testing till weekend at earliest, but thanks ever so much for the offer, will let you know :smile5:
