Circuit Breaker Query

[Doug99]

Hi Guys 'n Galls
Whilst working on some electrical kit in my shed, the circuit breaker for the house sockets tripped.
My concern is that my shed has its own distribution box and associated breakers: B6 for lights and B32 for sockets
In the photo, my shed breaker B32 and main breaker both tripped, but also my house main consumer unit breaker marked 'sockets'.
Why is this? I would have expected only my shed breaker to trip.
Any thoughts please?
Cheers
Doug

I see 16 amp MCB marked garage, and a 32 + 6 amp MCB in the garage, this should not be the case.

With caravans (often a 16 amp supply) I have seen the 6 amp after the 16 amp, so the 16 amp takes the whole load, and also 10 amp and 6 amp but to put a 32 amp MCB fed by a 16 amp is daft.

I will guess the 32 amp and 6 amp came as standard with the consumer unit, and who ever wired it just used what they had, and never expected the load to exceed 16 amp.

I hate to say this but your main CU needs updating
