Armored cable ...

Is the gland not made of the same material as an earth terminal?

You are ignoring the fact that a copper conductor is also captive within that terminal.

 

[Risteard]

I don't have the confidence that you understand how to interact with other people on forums and would strongly urge you to **** off

Delightful.

I guess I'm just too friendly...

What difference does that make?

 

[Risteard]

What difference does that make?

Copper and steel in the same terminal will react with each other. I already pointed this out.

 

[EFLImpudence]

Ah, I thought the objection was steel armour in brass terminal.

 

[ban-all-sheds]

Copper and steel in the same terminal will react with each other. I already pointed this out.

With reference to the galvanic table, please explain the relative difference between the corrosion which occurs with copper/galvanised steel vs brass/galvanised steel.

What's the difference between the internal / external ones as they all seem to be ip66 rated
Or the difference between 20 & 20S on this page please?

Also what's the name of the item / can anyone link to the item I need to attach to the hole of the collar (as per pic below) inside the junction box please? On the videos I have seen on Youtube they drill the junction box to put the screw through is that the same for the socket end of the cable too?

I realise that you are not an Electrician @ban-all-sheds but every Apprentice-trained Electrician knows of the dangers of combining dissimilar metals. Indeed they will have been taught this as part of their theory.

It's not rocket science though is it. All I've got from this so far is that I need to fit a £2 part to each end of the cable with very easy instuctional videos on YouTube. Looks like I'll just have to buy one of each type from screwfix and figure it out myself for all the help you've been so far
What's the actual point of you having any (supposed) knowledge if you're just going to sit in your armchair denigrating other posters & add nothing of value / interest.

You are a danger to yourself and other users of the installation. It is clear that you do not know what you are doing.

Hire a competent contractor immediately. Cease and desist from your dangerous DIY.

I'm still concerned that your earth from inside your house is not suitable for exporting to the garden. You also need to check the fault disconnection time is quick enough. You would need to measure your zs ie the resistance of the fault path to confirm that. For current carrying capacity 1.5mm should be ok for a single socket assuming no insulation.

Not a whole lot of explanation there though really is there. I think you're the one who doesn't know what you're doing. You don't seem to be able to comment on any technical aspect of this project whatsoever other than a load of old pony about metals and that the world will end when I plug my iPhone in to charge. Happy to be wrong but nothing to convince me in your sour rants so far.

So why not deal with the questions posed by other people then?

 

[John D v2.0]

Drilling would be ok as long as you can make a mechanically and electrically sound connection. But that's what the banjo is for. You can earth any metallic backbox with the normal terminal provided. But I'm far from convinced you want any lump of conductive metal outside the equipotential zone but connected to the electrical installation

Indeed.

And I realise that you will go to considerable lengths to avoid answering questions when you find the answers uncomfortable.
