Quite. If one is going to adopt that 'party line', then you have listed the rocks and hard places to which I referred.IMO He has 3 choices.
1/ He buys the test equipment that he will require and learns how to use it.
2/ He does the work and pays an electrician to Inspect and Test it for him.
3/ He doesn't do the work - he pays an electrician to do it for him.
There's no in-between - if the work is done it needs testing for safety.....end of.
So, OP, take your pick. This, in my opinion, applies to ANY DIY work.
However, if it becomes known that those rocks and hard places are what is offered in response to requests for advice which DIYers pose here (and similar places), many such people will probably decide not to bother asking for advice and ...... !! Whilst I respect your position, IMO one sometimes needs to be pragmatic/realistic.
Do I take it that you feel that no medications of any sort should be available without a doctor's prescription?
Kind Regards, John.
