Yes, on my favoured forum it's very politely made clear to DIYers that it's a professional forum and suggested that they should get someone in to do the work and we can't really give advice, and then those who are clearly 5WWs (chancers) are given short shrift.we can get frustrated with those who should know basic electrics, and are charging for their services..... But some commentary had spread to new members and those professing to be DiYers, this has been 'sat on' recently, so hopefully the forum will be peaceful for a while ray .
There is also an art to careful wordings of posts....... I'll master it 1 day :slap
I've mostly done commercial work; a small amount of domestic but now I'm doing industrial. I'm employed to improve the factory I'm working in but I don't profess to know everything, just as a housebasher might not be familiar with anything 3 phase or a DOL starter.
