NYY Buried Cable - Legit job?

[stevethesparks]

Even if it were ok at a 300mm depth (and I don't agree it is) how does the cable enter and exit the ground, is this part mechanically protected? Also, did the electrician cover the cable with yellow hep tape?

Hi, he has been and done the work replacing with SWA. I told him about the BS7671 and what NAPIT said but he just murmerred something about no traffic over the ground.

Just another question. He has not earthed the actual armouring part of the cable. It is a 3 core cable which one is earth. Should the armouring be earthed too?

Most definitely it should be earthed. How is it connected either end.

The whole point of SWA is that the conductors are totally surrounded by earthed steel wires. Without an earth connection, the wires would just become live if the cable was spiked, and the power wouldn't automatically be disconnected.

Is this an electrician doing the work?

@OsramMyers could you attach a photo of the glands used to terminate the cable? Should be a brass gland with a slide over black shroud on each end

Looks like he's coming back again.

Napit approved.....with some weird ideas, it seems!

Unless he just likes bringing it on himself.

There's always a chance he has earthed it. The OP would need to check both ends of the cable and know exactly what they were looking for. In addition, I sometimes bend the banjo inside the plastic junction box, so the little nut and bolt may not even be on view.
Firm evidence needed before the chap is condemned again. Plus, I'm not advising the OP starts undoing electrical items to take a look unless he 100% knows what he's doing and switches all power off first.

If the new unit he fitted in the garage is metal, and he's used proper glands it'll be fine, but I'm expecting a photo of a couple of compression glands... lets hope not... OP > no dismantling required
