Spot the Problems

[securespark]

This is a sub-main. The enclosure you see has a 63A RCD inside. There is no means of fusing down.The RCD is fed from the Henley and the cable you see at the bottom is SWA.

The cutout has no seals, nor the meter for that matter. The seals are missing because the black cable is a very poor DIY attempt at PME'ing a TT supply. The cable has been attached directly to the neutral block rather than the earth block present at the top of the cut-out.

As an aside, there are no meb's to the property, either. Lord knows what would happen if the supply neutral were to drop out.....And as for that DIY PME, if the supply is not suitable for conversion (ie the supply neutral is not grounded in several places), what then?

The supply to the top of the cut-out is the TT supply from outside. The lower pair go to the Henley. Then a pair go to the meter, which feeds an old Wylex board & one submain. The third pair of tails off the Henley (ie UNMETERED) feed that unfused submain in the first picture.

Nice, eh?

I'll have a guess.

Pic 1. SWA supply to an outhouse. Not glanded, and into a plastic enclosure.

This enclosure contains a 40A RCD, which provides no overcurrent to the installation. As the SWA is not glanded, the steel wire is not earthed, and possibly neither is the garage CU.

The garage RCD is fed direct from the cutout, before the meter.

I honestly posted that before I read your reply.

Just missed the TT part

I know you did!

I didn't honestly think I could see anything more wrong than the last installation of this kind I saw, but this really does take the biscuit. Well, a pallet-load really!

For the first time ever, as I traced the tails through and it dawned on me how the set-up had been wired, I actually swore out loud! I could not believe what I was seeing...

Thats got to be worthy of a picture being published in professional electrician

So am I right in thinking then that there is a bit of electricity theft going off Securespark??

Oh that is on top of the fact that this is in all intense purposes a bonfire waiting to happen

Nice PME attempt

So my unmetered guess was a gooden
