Curious fault after recent move

[James]

Without any test equipment, I would start by checking light fittings in the room below the shower, if there is any leak, it will often find its way into the lights of the room below.

Establishing whether there actually is RCD protection is the first thing! Pic of CU required.
There's a massive difference between the potential danger of a fault that trips a RCD and one that trips a RCD, especially if a shower is in the equation.

Corrected that for you!

OOps! OOps again! and again!

Sounds like a cross between Dick Dastardly and Brittany Spears!

Drat, drat and double drat! <twiddles moustache>

What is the point of the minimum character limit?

Too high!

I asked for the minimum word count in case people wanted to call me a w4nk3r,

now they still can, but they have to explain themselves a little more to inconvenience themselves!!

Kudos to you guys knowing it was an RCD without even looking I feel foolish not realising rcds were built in to the main isolator on boards like this.
In my defense the board is at the bottom of a tight cupboard and the writing on it is very small

So to clarify, it's the rcd tripping occasionally when the shower is/has been running.

Turning off the ring supplying the kitchen/bedroom will allow the rcd to come back on but that ring has to stay off for a good 30mins to an hour before it'll come back on without the rcd tripping again

The mcbs aren't labelled properly since the ring supplying the kitchen/bedroom is actually the one labelled 'spare' and the 32a mcb 4th from the right is the spare, which suggests they've been swapped over at some point right? Probably due to this fault?

If it is always shower-related then the above advice to look for water leaks is an important starting point to be checked/fixed before anything else.

That strongly suggests it is a socket or junction box related to that circuit that is getting wet.

More likely that the kitchen had some work done an an additional circuit put in, etc.

That is a very old board! Good to see the RCD is still working though, but at some point you ought to consider replacing it, maybe as part of a supervised assessment as your training progresses?

Again, if I were you I would be looking to determine exactly what circuits are in use and check everything out. Did you get an EICR as part of the documents for your new home?
