Morning all,

While I was visiting my colleague she mentioned that her upstairs lights
didn't work, so I had a quick look. She has what seemed to me like the
old rewireable fuses. But when I pulled one out (and it fell apart),
it turned out to be something different.

Ah, I found it. It's a MEMERA 3 module. Not that easy to get but
available online. Can't see any MCB replacements, so will probably have to
go with the original (£10!) part.
