Cable size

[uksparks]

Hi,

I am going to be connecting an out door power supply, away from the building, its all metal casing.

The supply is 10mm, I am using a 3 core SWA for part of the run, the inside part was going to be in twin and earth, but then I was just thinking, going on table 54.8 section 544.1, am I looking into this too much or does it need to have a 10mm earth as its extraneous metal which is fixed into the ground?

In which case I was just thinking of running 3x 10mm inside the building so the earth is 10mm too to them comply with min size of bonding conductor.

I am right to make it 10mm throughout the entire run aren't i?

They look like they have all the right conductors through them. I just don't see why they've taken the neutral through the check meter?

Which ever way you look at it, its very poor. Should get them back to correct it & then slap them with a large wet fish.

Ha! just noticed those now that you mentioned it , those nuts will have to be changed to brass as well as the slot cut

But they each appear to have a single phase circuit going out to a meter then coming back, all through the same hole so there shouldn't be any reason to change them.

I cannot see the picture clearly enough, give me a moment to have a closer look

Edit: Nope, still cannot make it out properly, I will have to take your word on it lol

yes the ones going out the side are for the meters, which I will be putting another one in for them the same as it happens.

The ones at the bottom, ill see if I can fix that and get it through one hole etc..

Does this help...

Nothing is even labelled, its not acceptable is it really, maybe I can get a bit of work out of this and tell them im label it all.

I was going to ask you if you could get your hands on the overall installation Line & Neutral design currents, but seeing these pictures, I doubt any exist (with any validity!) :smilielol5:

They are OK as they are 1P & N in each hole.

But installing them a little bit more sensibly I assume? Lol, I don't think they could have made more of a hash of that if they'd tried.

I can't see why they would the neutral out to the meter and then bring it back into the board to bodge it onto the outgoing cable? And as for the bodge and tape joints??

The meter needs the neutral to operate does it not? How else would you have done it?

I thought the tape was just for ID??? Daz

Not for monitoring purposes though.
