Terminating SWA

[ban-all-sheds]

the new property is newer and the entry points much more in-your-face.

How in-your-face?

How visible? How large a box could you have? Would an outside socket make sense there?

Any quality enclosure with cables taken in through the bottom will be waterproof.

If a socket would make sense you could fit a 2-gang Masterseal with a cable coming out of the house and up into the bottom of the enclosure, and the SWA running from there to the garage.

And then, as roxburd asked, how do you earth the armour?

We don't even know that it isn't 2-core SWA, and that the problem isn't one of maintaining cpc continuity rather than mere earthing of the armour.

Yeah, 3-core, third core as cpc. Non-RCD feed from head end to RCD-protected garage CU.

Make that an RCD Masterseal socket then....

I would personally say that an armoured cable cleated up a wall and then vanishing inside at an angle would be far neater than a box, and certainly "less in your face".

Or....

Are you taking the cable directly into the back of a socket, and so have to terminate the SWA outside?

The last time you took the SWA inside, I assume you did gland it?

And with the size of the new Masterseals, the gland and TRS gland underneath would be concealed by the oversized cover!

Personally am not a fan of the new Masterseal range.

Last time I brought the SWA inside and up to a metal junction box, terminated there and then up to the CU on T&E. I did that on both ends. I used a separate boxes to get a better/stronger mounting point for the SWA terminating gland.

This time, I'm doing pretty-much the same job (except I don't need to dig a trench this time!).

I thought a box would produce a neater job. But obviously I need to earth the armour and I'm not real impressed with the idea of trailing a separate earth to the box (as I would have to if I brought the SWA inner right up to the CU).

I'm starting to think that although SWA right through the wall (as I did last time) might not look quite as professional, it might not be so bad and avoids all the weather-proofing issues.

So how are you proposing to terminate the SWA if you take it direct to the CU?

I am suggesting taking a 4 milli cpc to the SWA box on the outside. If you are worried about how it looks, run the SWA inner and the 4 milli in trunking.
