Help: RCD won’t switch back on

[boxst]

The downstairs / upstairs ring just tripped and it won’t switch back on again. The weird thing is that all the individual fuses stay “on” (and even if I switch them off) the main one won’t stay on.

It doesn’t have any “feel” to it so I wonder if it is broken ? Any help appreciated as the freezers are happily defrosting.

Edit: even if I switch off the whole power (red switch) the switch doesn’t stay up.

Yes. I’ve switched the whole box off and the switch still doesn’t reset.

Thank you for the replies. I did all of those things before posting — which is why I’m a bit flummoxed.

I guess it’s fhe RCD and that particular switch which controls all the switches to the right. The lights etc (everything on the left hand side) is fine.

Out of frustration, was playing with the switch quite rigorously and it switched back up. So I guess it is broken or on its way out. I have the British Gas (Homeserve) people coming tomorrow morning so we will see.

I think the RCD should stay up with the main switch in the off position, dont think the Crabtree ones (or any for that matter) need power to stay on. Must be knackered, although a fault on one of the circuits could have broke it, might just need a bit of a tap to free any seized parts inside if its not been operated for years. Bet the OP gets talked into a new consumer unit though.

I haven't tripped it again, but may do to check to see if it is broken. Not too sure about 'talked into' as all parts & labour are covered by the BG agreement.
