I'd leave the buying to the electrician tbh.
A TT supply can only be converted to a TN by the electricity distribution network operator.
That will definately cost more than a Dual RCD board
Told you I could spot a PITA customer at 10 paces
Hardly worth the aggro of no, or limited, warranty on the work done by the electrician, as you probably won't save as much as you think by the time he's increased his labour charges to offset the profit on materials that you're taking away from him.I will be doing the buying as my uncle is the manager of an electrical wholesalers and can do me good deals.
Are you going to get a 200mS disconnection time with a time-delayed RCD?I can't imagine all circuits being non socket and on the current non RCD side in pyro/metal conduit, surface mount etc, but it is possible"Probably"?..knowing of course that a new CU is more likely to bring the installation up to current regs and a 100mA (S) RCD probably wont.
I think that what he means is that his previous contributions to this site now make more sense.What do you mean so what?
FFS! How often do you ever contact the local distributor for anything? Get real, what are you wiring? EXPERIENCE and PROPER training negate the need to post stupid questions like this. If you did contact the local distributor it would be highly likely you'd end up speaking to someone in Bangladesh, who'd have about as much of an idea about electrics as some of the people on here.

I'm sure you are just trying to be helpful, but as you will grow to see. All you are doing it encouraging people who aint got a clue to attempt it, potentially causing injury or death to someone, doing electricians out of work and encouraging people to break the law.
Why go to college and do all your exams to become an electrician if people on here are going to give (sometimes misguided advice) on how to do it?
Absolutely not. It encourages people to attempt something they don't understand and know little about. Someone can look at this and do it in their own house and it may work, they then decide through this recently discovered confidence that they can be an electrician (as they've done it in their own house). One of these new electricians calls round to your mums house and do some wiring, only this time they do it wrong. Not only has it cost your mum money but could also cause injury or death.
Electrics aint wood or bricks and it won't get your carpet wet. Fine DIY like this but not electric. It dangerous, starts fires and can kill. Not to mention the work if carried out will be illegitimate.
Posts like this do not help.
Argument and rhetoric such as yours are dangerous and could be applied to anything in society. People are going to take drugs come what may, so why not tell people how to make their own?
In Canada people can't even buy a socket unless they are qualified (note I don't use the word competent) and look at their economy and building sector in comparison to ours.
3 week courses to become and Electrician or a Plumber. A joke and a disgrace!
If you're not a competent person, then no. I don't think you should be working on electrics.
You've obviously no idea what a 4 year electrical training course involves, so your comment on training means nothing to me.
Yes, a with significantly higher than I/\n trip test current they must trip quickly enough (60>mS <200mS) to comply with EN61008 or 9, which is where the daft 2x value came from in BS7671:2008 which was then deleted by the corrigendum.Are you going to get a 200mS disconnection time with a time-delayed RCD?
