I would like to thank Devspark for explaining where all these spurious registrations and posts are coming from. I thought something was going on but guessed wrong what it was.
I suppose it's inevitable that a DIY forum in this area would act as a red flag to some trading electricians, who may perhaps be going through hard times. It seems a shame though, as nothing has really changed on the DIY front except that the internet makes in easier for DIY enthusiasts to get better informed and not make stupid mistakes.
There are always going to be people who don't realise the dangers and legal consequences of what they want to do, and a forum like this can only be a help in that area.
In the case of the OP, he initally made two mistakes.
Firstly, he didn't know that if you buy a Henley block, it may be a single or a double pole depending on which you ask for. Personally I had only come across double pole ones, so learned something from his question. As he found that the Henley block would not achieve what he knew it had to do, he asked about it here. I take the question to mean "the Henley block I bought is single pole - is that normal?". Which is a sensible thing to ask at that point. I don't see why everybody then assumes that the OP would go away and join the tails together, which of course would have been much worse than stupid, he probably would have survived the experiment.
The second mistake was to be taking on the job without realising the legal consequences, and the possible dangers to others. When this was explained the OP stated that he wouldn't procede, as he had learned (from the forum) that it would be foolish. To me that was a good outcome, and the thread should have ended there.
However people then piled in, probably without carefully reading the thread, and started name-calling and bullying. These post were pointless, and probably worse, were likely to alienate the OP.
OK - had my say. Thanks for listening.
