[QUOTE="Evans Electric, post: 229777, member: 1408"] May I just add that I'm not sure if all the DNO people know the difference and that definitely a PME sticker on a cut-out may not mean what it says . ( Main reason being that the link can be missing between N and the earth terminal.) And I assume that the DNOs are no longer installing PME as it doesn't appear in the BS7671 list of types of supply. I think that in this area anyway, they may be upgrading supplies from TN-S with poor Ze to TN-C-S and stickering it PME . [/QUOTE]
