Mark Coles:
Hi,
I need to step in here and apologise on behalf of The IET for any offence caused by the use of this term in BS 7671. The content of Appendix 5 is taken directly from HD 60364-5-51, last published in 2009/amended 2013, itself based on IEC 60364-5-51:2005, where the term is used. The earliest version of the Regulations I have at hand is the 15th Edition from 1981 and the term is used there too, so, sadly, it's been in use all this time. My guess is that as Appendix 5 has not had a massive amount of change at IEC/HD level, the use of this term has not been scrutinised nor challenged. Thank you for bringing this to The IET's attention, I'll now raise it at committee level to seek a solution.
