On the search for mk rcbo.....

Yes. 3 shower circuits. I don’t know why... oil fired central heating, surely they can get hot water from it too.

It’s a sprawling barn conversion. Rewired in bits over the years. Shower in the “guest wing” I believe.

RCBOs were never common for these boards. I've only ever seen a few, 2 of which I have here somewhere, for some reason.

I popped over to my wholesalers this morning to price up a new board. YESSS are now stocking Fusebox brand, which should save a few quid.

Nah that's the older stuff that's not compatible. I'm working with one on an occupied rewire at the moment. someone has actually fitted a modern sentry breaker, but it's definitely not a legit fit. It's bodged in with a flying lead off the busbar.

MK did make a retrofit kit to allow new breakers to be fitted in to the old boards, so if it's a properly made flylead then it may be legit.

Ah, didn't know that. I'll have a look next week.

Part number 5567s it's discontinued now as far as I know.

That is them. As I said rare as hens teeth.

Not worth bothering with now, better to renew the CU to something with easily available parts.

 

[Andy78]

Yep, turns out it was a proper kit. And whoever put it in had some fun in there

Good photos Andy.

Is that thermal damage from a failed attempt previous or the kit itself failing now?

Edit : I didn't look at the photos of the metal case damage. Duh!!!
