Mains IEC Connectors, I never realised !!

Makes sense. 60 dB, normal speaking voice, to 70, clearly audible. 70-80, likewise. But at the extremes, no.

Not really it's only at one extreme ie -xdB that it ceases to matter. It's not about going up by 10dB but about dropping something down by 10dB. Once it is below the level you can hear it doesn't matter whether it gets lower.

One: I'm not giving advice. Two: It's brought, not bought (buy/bought; bring/brought). Three: You are correct, I don't have knowledge of electrical reg's as I'm not an electrician. Four: Which is why I've mentioned sth relevant that I'd just been told. Five: The 2 reg's are: 537-04-01 and 537-04-04, which cover the same ground. You would know of these, of course, and I've no evidence or intuition that this info. is incorrect, as you say it is.

As I'm happy to learn, if you refute the validity of these reg's as you appear to do, I'll be happy to be corrected.

I suggest you should purchase a copy of BS 7671

Why? You haven't addressed any of my points when ostensibly you're qualified to do so, nor substantiated your denigration of my post.

This worth a read.

Isolation and switching for mechanical maintenance

The topic of heat-damaged shower pull cords was recently discussed on the IET EngX forum, not for the first time it must be said. This article does not look at the reasons for shower pull cord switches burning out, I will save that for another day...

Those of you with TT power have to treat Neutral as hazardous and install two pole isolators. The local earth is not treated as reliable.

I just mentioned that in another cable thread

If it’s the Naim/Pardo one, I was disappointed nobody bit to enquire about my recommendation of C2G power cables, those being the first recommendation Amazon gave me at a cost of something a bit under £3 for a 1.5m

That's the one. Give it time, might be too high end though!
