Well - I don't know whether you'll read this, or even take it on board, as I fear you might be one of those people who refuses to accept responsibility for his own mistakes, lack of attention and general carelessness, but we'll give it a go.
Firstly, forget all the cross-talk between people talking about their own questions, and concentrate on the exchanges between you and me, which seem to be causing you some grief.
You said:
As I want to replace my old Consumer Unit with a New Unit with an RCD.
Would this give protection from shocks as a RCCD would, or would the indivual circuits need a RCCD?
I said:
What's an RCCD? What do you think it does?
You said:
Are you trying to be clever or what??
I said:
No - I'm trying to get you to concentrate, and think, and learn...
Do you not think you should concentrate? Do you not think you should learn the difference between the letters RCCD and RCCB? Do you not think that you should be able to spot the difference between a "D" and a "B" and wonder if "D" really can stand for "breaker"?
You said:
RCD = Residual current device
RCCD = Residual current circuit breaker
So would it be better to have one of the above as the incoming protection or have a Isolator with individual protection circuits.
Nobody is doing you any favours if they spoonfeed you, and allow you to approach electrical work with a sloppy attitude. Nobody is doing you any favours if they circumvent your carelessness by working out what you meant, and doing for your question what you should have done in the first place. And why should they? What makes you think it's OK to come here and ask questions that when taken as written are rubbish, in the expectation that we will take the time to try and work out what you really meant? If you can get those two letters mixed up, and not spot anything wrong, who's to say that you wouldn't get others mixed up, like L, N & E? Because let me assure you, if you touch the wrong thing, or wire things up wrongly, electricity isn't going to say "I know what he
meant to do", and fail to obey its laws, it's going to turn round and bite, and its bite can kill.
So I don't have any regrets that I tried to get you to smarten up your act and start
thinking about what you're doing.
I said:
Anyway - RCDs and RCCBs are one and the same thing.
<followed by a link to reference material>
Surely you want to learn more?
I said:
It would be utter madness to fit an RCD per circuit. If you want protection at the individual circuit level, fit RCBOs rather than an MCB and an RCD per circuit.
An isolator and RCBOs is always a better solution as it increases fault discrimination and decreases inconvenience.
It also increases costs considerably.
And surely that was the answer to the question you meant to ask?
You said:
There seems to be alot of arguments about the terminolgy and spellings of things people ask in a simple question and not getting a straight answer they are looking for in the original question. (B-A-S)
You mention motoring forums. I don't know if this analogy still works, in these days of engine management systems, or if not if you're old enough to remember it, but if I was talking about setting up the valve timing on an engine, and got BTDC and ATDC mixed up, would that matter? I mean, it's only one letter different, how important can that be? Well - you try having your exhaust valves close 20° BTDC instead of 20° after, and see how well your engine works...
I didn't argue a lot about spelling or terminology, I asked you
once what you meant by RCCD, when you still didn't get it I pointed out what you'd done wrong and then I gave you the answer to the question that I thought you meant to ask, which was not about RCCBs at all, but RCBOs.
You said:
Why can there be a simple tip or answer ????
Shall I repeat it?
If you want protection at the individual circuit level, fit RCBOs....
An isolator and RCBOs is always a better solution as it increases fault discrimination and decreases inconvenience.
It also increases costs considerably.
How much simpler do you need the answers to be?
You said:
Shan't be back for a while, I'd be afraid to ask for any tip.
That may be just as well..
