Concentric Cable

Ask any electrical wholesaler (useful one that is, not a 'shed' like SF) for it . They'll get it for you. It's BS7870 cable, BTW.

 

Ouch!.

 

Any wholesaler can deal directly with any cable supplier, and while they would usually be purchasing split concentric, they will be able to obtain straight concentric just as easily. You may find the counter staff are confused, but be persistent in your "straight concentric" request.

I do have to ask though......what's it for! It's not covered by BS7671, and never has been.

 

Or find a cable jointer who works for the dno that is looking for some beer money ;-)

 

Hmmmm!

 

You might struggle to get hold of the straight concentric, DNO use only, split con on the other hand is ace, terminate it like twin and skin

 

Although the neutral is connected to earth internally at the generator, all generator outputs I have seen have been LN&E, this to me is a TNS supply. Are you just distributing the L&N from the generator, if so sounds more like TT than TNCS, whats the earth rod situation?

 

I agree. The generator output should be treated as TNS as it leaves the genset.
