Additions and alterations are going to be costly....

Considering that 'Wiring Matters' magazine has the IET name on it do we take that to mean that it contains the opinion of the IET?
I doubt that an article as important as this could go to print without authorisation of the IET and if that's the case then that's how the series of regulations in that article should be interpreted.

However, it does seem to pose more questions than answers...... clear as mud? You bet!

When my son (now 30) was at school as a 14 year old the teacher asked if anyone knew what were the two types of transistor. My son answered Bi-polar and Field Effect. He was told he was wrong and there were PNP and NPN.
From that day he looked at his teacher as being a buffoon, and took no real notice of what he said as he felt the teacher did not know anything.

Of course in most items the teacher was right but because of this one mistake he had lost credibility.

It is the same with BS7671:2008 we see the mistake with cables buried in walls where they have failed to say it does not include SELV and we no longer trust anything else it says. Especially where there is some ambiguity. The division of circuits has not really changed what has changed is the ambiguity has been removed.

Lets face it the writers are selected because of electrical ability not as being a professor in English.

I saw a notice on Shape Fell before M6 was opened “Beware of Man eating Haggis” and I had an image of a man being chased by a Haggis in my minds eye! This happens in many places does one door mean only one door or at least one door?

And what we are reading is how one man thinks we should intrepid the book.

The 14th Edition of the regs was slated by many in the profession because it was written almost as an instruction manual, containing precise details of how to tackle a specific job.

Since the 15th, which I started on, it has altered radically, becoming far more open to interpretation. This is why I call the regs my bible: just like the bible, there are many interpretations of it!

I think this chap is reading too much into it. To take the above example of Ban's, it is highly impractical (for obvious reasons) to expect an electrician to strip a property in order to check that every element of the electrical installation is just so.

Ditto the idea that if you do a board change, you cannot put "LIMS" on the EIC. Well, unless you inspect every inch, there are going to be limitations on your inspection. The same applies to PIR's.

It simply is not feasible to strip an installation down & inspect every last morsel of wiring!
