I thought it might be useful to have a list of questions that people who think that changing a CU or rewiring a house is a P.O.P. could be asked, hopefully to show them that it really isn't as trivial as they think.
I'll admit to a level of naivete, but surely sometimes there'll be people who'll end up taking advice to either go away and learn a lot more or get an electrician if they can see that there is a lot to know rather than think the advice is aimed at protecting a closed shop.
Anyway - here's my starter for 10 - would welcome discussion and further suggestions - my idea is that when complete I'll put the list in the Wiki and ask Admin to delete this topic to not leave a record behind. The questions should all be justifiable, and I think we should avoid a list so long that it looks like deliberate obfuscation.

- What are the 3 different types of domestic single-phase supplies provided in this country, how would you recognise them, and what differences do each make to the requirements for the rest of the installation?
- How do you propose to isolate your supply so that you can connect up your new CU?
- For a circuit to supply a <thing> (doesn't matter what), how would you go about deciding what cable and protective device to use?
- What are the rules concerning cables concealed in walls, partitions and under floors?
- Which circuits must be RCD protected?
- Explain what tests you would carry out on the installation - please cover the sequence you'd do them in and at what point you would energise the installation, and for each test explain what is being measured, why it is important, how you would carry out the test, what sort of results you would expect to get if everything was OK.
