I did edit that comment to read "in" not "from" (my error), but my EDIT marker seems to have been excluded.

What does this refer to? Which comment?

The one you quoted about the origin of the definitions.

Thanks - so BAS's and my 'first thoughts' were correct. As I said, I was doubtful that MCBs were around back then, but clearly they were!

Crabtree MCB's were popular back then, for commercial & industrial sites. Dark brown in colour.

Fair enough. I've never had anything to do with commercial or industrial installations, and I think it was well into the 70s (maybe even later) before I saw, or even heard of, MCBs in domestic installations.

I never really ventured much into domestic, but the first I saw were the Wylex MCB's which you could use to replace their fuse wire bridges, with two buttons.

Same here (although ones with levers, rather than buttons) - but, in my case, that was well into (probably in the latter part of) the 80s.

Crabtree C50 I think.
