Distances for supports - AWOL?

[Rockingit]

I'm either going mad or blind, but I went looking in the brown book the other day to find the small bit where it gives minimum support spacings for cables, horizontally and vertically. Except, I couldn't find it anywhere. Not in S.5 (where you'd expect), not in the appendices such as 4 (also where you'd expect)..... so where's it gone?! Or was it never there to start with and is an OSG thing?? Or have I missed some removal back in time?

Confuzzled. R.

D'oh! Just answered my own question - it's me going senile. It's the OSG. As you were.........

mmm Appendix D in OSG but no blue Regulation Reference in tab so perhaps not in the BBB?

Exactly. So it's even more of a suggestion than a regulation! And another bug of mine is that whilst 7671 itself makes references to all the applicable other standards that it references (easy one is BS1361 etc etc) and even has several pages of tables that list them concisely in the back, at no point do they ever say "this bit's in the OSG...". Probably because BSi can't make any money off a book published by the IET!!!

Also in Appendix G of GN1.

As seems to be the norm., these days, just whacking 'the odd clip in' will probably suffice.
