Everyone. Thank you
This forum is great

Yes it is.

Ps r u doing it? Have you got calibrated meter to check RCD. Test button does not confirm it works properly with vindication, I would want it tested. I've fitted a fair few off the shelf that are duds.

Dont make em like they used to. I prefer the house brick ones

I'd have to disagree with that statement, RCDs if anything, HAVE improved over the years. But nowhere near to the point i'd trust/rely on them as my main form of protection against earth faults, as i've often stated on TT threads here. They still have a long way to go in the reliability stakes... lol!!

You're allowed to disagree :86:

All I meant was, in my (not very) extensive research of trip times of 30mA RCDs, the oldest ones are without fail...faster.


As for reliability, I know not, i never fitted any so don't know if they were a bagg of ....nails off the shelf. Spose could/would have been!

You maybe right, but i wouldn't say that i've noticed that older RCD units being faster than the present day units. As far as i know, the same tripping and time requirements associated with 30mA RCD devices, have remained the same for many years now. Even then the accuracy isn't great!! lol!!

The older RCD units (not got an image or a BS number for them to hand - sorry!) seem to be capable of lasting the test of time longer that the newer stuff. Lack of routine testing on the newer ones may be a contributing factor, but so many failing even mechanical tests that I come across. It's a sorry state of affairs they are so bad, especially in relation to TT systems when they can be all the more important. But with supplementary bonding starting to become a thing of the past due to RCD's its only a matter of time before someone is killed (hopefully an MP! Ideally House of Commons, whack the lot of them in one go!) because of failing RCD's.

yer but im sure even if there aint no reg, if just replacing the shower it would make you sleep better at night and im sure you will be taking responsibility for the install so it should really need to comply..

While I would also be inclined to fit an RCD on a replacement as well....it's worth pointing out that just 4 years ago there was no requirement to RCD a shower at all....it could run straight off a 3036 fuse if you wanted......and everyone slept at night just fine.
