Double socket spur from MCB?

[JohnW2]

But it is helpful to tell him things which are not necessarily true?

What would be helpful would be to give him complete information, rather than a statement which would raise doubts in his mind without any indication of what was being suggested.

Having said that, I strongly suspect that a good few electricians would say/believe that it is true that an unfused spur from a ring was only allowed to supply one socket - on the basis that such is what is said in the infamous Appendix 15, and that they hadn't even thought of running a 4mm² spur from a 2.5mm² ring (something which, again, is not mentioned in App 15). Indeed, as we know, some are not even convinced that such would be 'compliant'.

Kind Regards, John

Don't forget I was talking to you.

In other words you strongly suspect that a good few "electricians" don't actually understand the science behind circuit protection.

IMO any "electrician" who doesn't fully understand what protection a cable requires should face prosecution for fraud.

I don't doubt that there are at least some who don't understand that, but it's not what I was talking about. I wasn't talking about understanding of the science but, rather, of interpretation/perception of the regulations.

As we know, there are things which appear fine in terms of "the science" but which are, or may be, contrary to regulations.
