What do you code these? Commercial installation

What are the odds on that SY braiding not being Earthed?
Pretty good I reckon

Does it require earthing?
It’s not an exposed-conductive part as it’s under the clear sheath.
It’s no use as a CPC.
I doubt it would function as an earthed metallic sheath if the cable were penetrated by a metallic object.

526.9.1 Connection of multiwire, finewire and very finewire conductors
In order to avoid inappropriate separation or spreading of individual wires of multiwire, fine wire or very fine wire conductors, suitable terminals shall be used or the conductor ends shall be suitably treated.
It does not state “ferrules’.
A long standing practice for protecting such wires is to twist the exposed strands together and then fold them over.

Whilst we are allowed to design, install and initially verify installations to the 18th edition, inspection and testing of existing installations should be conducted to the current edition.

Hmmm, isn't a ferrule a terminal?

And, in BGB: BS7671:2008:Amd 1:
526.9.1 In order to avoid inappropriate separation or spreading of individual wires of multiwire, fine wire or
very fine wire conductors, suitable terminals shall be used or the conductor ends shall be suitably treated.

No a ferrule is used to treat the end of a conductor.
The terminal is the part with the screw.
In the case of MCBs, the terminals are designed so the screw part of the terminal does not make physical contact with the conductor.
The neutral bar however in the top picture has nothing to protect the conductor from the screw.

Have you got a picture with the lid on? Never seen that set up before.

No I haven't but I can tell you it's a Hager. I won't be going back as after pointing a few things out to the owner he has appointed another electrician to do the report.

I hadn't noticed the hinges look nackard in the photo too, and also there's a window for the breakers? how well does that fit? that thing is basically f****'d in so many ways

The reason the hinges are nackard is because there is a water pipe obstructing the opening of the lid and it has been forcibly opened in the passed.

Good point,Swa as a covered sheath,& not always used as cpc,but is earthed

in other words he wants a tick-box satisfactory report for peanuts. yous best off out of there.

Exactly, thanks for confirming my initial thoughts

I am concerned that a ‘C’ type MCB has been installed

I can only see 3 different B types and a SqD D type?

20p : Containment - when the lid is down is the IP rating achieved? Can the lid be secured so that a tool is needed to open it? If not, then seeing a bit of exposed copper makes me go for my C2 bat. Am I too harsh?

I meant D.
