Would the team like to guess the date of the Wylex CU with 100 mA RCD main switch

I don't have an answer but would be interested in opinions

Thanks

late 80s early 1990s

I base that on the fact that, around then, we had a meter moved (long
story) and I changed the CU. The one I fitted, as best as I can recall,
looked very like that. It was certainly a Wylex.

Post-1983 for 15th edition which introduced BS 4293 RCDs and pre-1992
for 16th edition 1st amendment where they became BS EN 61008, judging by
the general look of the thing, I'd say the earlier end of that range ...

When I took away the shed the internal cu was a metal clad thing with one of
those big lever switches on the side and a ceramic main structure inside. It
was certainly built to last. I imagine it had been repurposed from when the
main house had been rewired so it dated from 1939. It was really pristine
inside but of course used fuse wire fuses, very un user friendly.

Its a Wylex NN style CU, with Type 2 MCBs rather than the modern
lettered types. So probably mid 80's at the oldest, and possibly up to
early 90's at the newest.

Very precise, I was thinking just pre 15th Edition, but the implementation of the 15th was delayed by a few years.

My garage still has a 3-phase, metal-clad isolator with BS88 fuses for
each contact. When I moved in, the garage was fed by a piece of T&E with
no physical protection and with two contacts of the isolator cutting
both live and neutral. I have since re-wired it with a SWA feed cable,
fed from an MCB and RCD (new CU in house) and used two contacts to split
the live - one fused 20A for the sockets and the other 4A for the lights.

I should change it for a small CU with breakers, but I never have to
touch it at all normally and have only had to isolate it once when I was
adding more sockets and lights.

Wylex started to use NSB MCBs instead of NB's in the mid to late 80s.
