Earth Sleeving ... what's it for?

gkenyon

Prompted by a comment in this thread:  Have you ever done it like this?

I thought it would be worth airing some opinions on the purpose of 'earth sleeving':

(a) According to BS 7671 (what Regulations require it, and for what purpose?)

(b) According to other risk reduction measures

  • Some great ideas, and yes most of the referenced Regulations are relevant in one way or another.

    AJJewsbury said:
    543.3.201. And as that only applies to c.p.c.s ≤6mm² and comes under the heading 'Preservation of electrical continuity of protective conductors'

    Main reason, of course, is it's actually required by BS 7671 specifically for the purpose covered by 543.3.201 ... well done Andy and anyone else who got that Reg !

    The thing that prompted me to the post, was someone saying they always make sure the cpc in relevant cables is covered right back to the sheath ... and not simply a short length for identification purposes.

    543.3.1 protection required against mechanical, chemical, and electrodynamic effects.

    I doubt that the last will be relevant to the average back box.

    It is difficult to see how a loose sleeve could keep out chemicals.

    Which leaves mechanical effects. Is half a millimetre of soft plastic really capable of providing significant protection?
