Strange, I checked the link in my post and it is correct.
"Then" wasn't all that long ago. The world is not going to end by adding one more socket with 100mA RCD protection instead of 30mA in a house which is already full of 100mA-protected sockets.
Be that as it may, the ONLY advice which can be given is that the current edition of the Wiring Regulations is the one to be followed, and the current law obeyed.
The whole thing. Depends on your idea of "costly".
Assuming that you are going to have lights in it, and sockets, and want the cables to be concealed then you will not be able to have any of that put onto your existing CU. So in practical terms it will have to be replaced, either before the loft conversion is done or as part of it, unless you want a separate CU just for the loft.
And what does the current law demand? Only that the work be "reasonably safe." As you are well aware, it does not require compliance with the latest edition of BS7671 (or any edition for that matter). Your statement is likely to be taken as suggesting that the law can be satisfied only by following every detail of the current edition of BS7671, which you know is not true.
What do you mean by "lightweight" and "loaded" sockets?
Yes, I'm going to have a bedroom and shower room in the loft and the wiring will be concealed. I'll ask them about replacing the CU.
Lightweight = ordinary sockets that are just sockets and nothing else
Is this Dodge City? Are there other cowboys here?
No - you believe it is an opportunity to recruit more people to your cowboy gang.
Would the fact that it's a lie do?
That would be illegal. 100mA is not reasonably safe.
When was a 100mA RCD the accepted norm for sockets?
Why can you not get it into your head that things change? The way you cling to the past, with your "it were good enough when I were a lad" attitude is pathetic.
Then I suggest you ignore all the nonsense from PBC about the technicalities of complying with the law without taking any notice of the Wiring Regulations. Unless you want a huge fight with Building Control on your hands, to the extent of risking not getting a completion certificate from them, and unless you want to find it all but impossible to get an electrician, you've got no choice but to have the work done in compliance with the current version of the Wiring Regulations.
It's nothing to do with the meter. Isolating a circuit by turning off the MCB does not disconnect the neutral, only line, so if you happen to make a contact between N & earth the RCD will trip. It may not be desirable, but there's nothing wrong. If it never happened before the meter change then either you never accidentally made that connection, or you had no earth before and they sorted that without telling you when the meter was changed.
Ah, got you.
I care about an electrical installation being reasonably safe, which is all that English law demands.
Ever the response of somebody who can offer no other reasonable argument - Resort to insults.
No, because it isn't. Are you seriously suggesting that a socket with 100mA is unsafe just because it's protected by a 100mA and not a 30mA one?
Nonsense. Our standard GFCI's here provide protection to 5mA, which is obviously better than 30mA. Should I try to claim that 30mA RCD protection is therefore unsafe?
When it was standard for whole-house protection, as in the OP's case.
Just because what is done as standard today has changed does not automatically render something done only a few years ago as being dangerous.
Where have a lied about safety? I acknowledged that 30mA protection provides an extra level of safety. That does not mean that the existing 100mA protection is unsafe.
You may feel insulted by that, in the same way that King Salman of Saudi Arabia feels insulted when people call him an odious tyrant, but I did not say it to insult you - I said it to express to you my opinion of your awful behaviour.
I'm saying it is not as safe, and therefore it is a lie to say that there is nothing unsafe about it.
This is here, not there.
It's been more than 10 years since it was 30mA for supplementary protection.
It renders it automatically deprecated, it renders it automatically obsolete, it renders it automatically non-compliant and it renders it automatically no longer to be advised to be done.
Yes.
It means it is not as safe, and therefore it means that more people are likely to be harmed by relying on it, and more people will tend to die by relying on it.
The fact that "A" may offer increased safety over "B" does not automatically mean that "B" is unsafe. "B" can still be considered reasonably safe even if "A" offers a greater level of safety.
I await with interest your explanation of how the American milliamp differs from the British milliamp.
That is not what "reasonably safe" means. By your logic I could argue that your advice to install a 30mA RCD socket is not reasonable and would therefore be illegal because you could use one of these instead:
And the Wylex board and 100mA RCD in the OP's picture are clearly older than that. And 10 years ago was 2005, not exactly the dark ages of electrical safety.
But it does not render it no longer reasonably safe.
There you go with tirade again. I have nowhere suggested that Otorongo flouts the law, and would not in any way encourage anybody to do something which I would not regard as being reasonably safe. You seem to have a very twisted interpretation of what "reasonable" and "reasonably" mean in the context in which they are being used here. The regulations, as you well know are not law, albeit that calling them "regulations" suggests that to many people.
Right, so you're obviously quite happy to advise the use of 30mA RCD protection, even though it's clearly not as safe asusing the 10mA device I referred to above. Doesn't that mean that more people are likely to be harmed by relying on your advice to use 30mA than if you had advised the use of 10mA protection?
