As above plus
grey should be used a N with blue sheath.
armour is not earthed.
 
Things wrong in this picture;

1. Basic insulation showing (meter cabs are not considered suitable enclosures) interestingly site applied insulation (heat shrink) is no longer classed as suitable in an application like this either.

2. Black being used as the N (personally don’t see a problem with it and I’m not aware of any regs which explicitly state black cannot be used as a neutral) but the NICEIC ran a campaign to “de-neutralise” the black. Bigger problem IMO is no sleeving to identify it as a neutral.

3. Difficult to tell from just a photo but that doesn’t appear to be a 25mm SWA and the cut-out says 100A fuse fitted. So OCPD is too large for cable.

4. Whilst not a 7671 reg most DNOs/DSOs specify that meter tails can only use the cutout fuse as an OCPD where the tails are less than 3 metres.

5. SWA braid is not earthed.

6. SWA is not terminated correctly.
