I'd much rather have someone like John on here giving out knowledgeable advice than someone like yourself giving out not just wrong, but dangerous advice to DIYers.
I'm sure you do, as he/she doesn't question your competence. You'd rather listen to a DIYer than a senior engineer at the IET.
That dear readers is how low the trade has sunk, and why you are getting ripped off daily by course cowboys.
In the post where you quoted the IET, their post started with IET wrote.
I am required to preface my remarks by saying that I have no authority to interpret the requirements of BS 7671:2008(2011), Requirements for Electrical Installations, however, within that constraint, I hope you will find my comments helpful.
It's a jump to now claim this was advised by a senior IET engineer.
Just how are sparks ripping people off on a daily basis?
