We've got a new build with all the T&E, earths and 25mm SWA coming through one 60mm cutout in a stud wall. What's the neatest way of terminating the SWA?

I'm not convinced that a gland with the earth tag and nut 'floating' loose within the CU, and the 'tails' then running as usual is going to be best practice here? Or is this how you would all do it?

As long as it is earthed at one end then it complies.

This happened to me a while back where the builder brought it through with the T&E and boarded.

I managed to gland it into a galv box which was then behind the DB. The gland was then not accessible but the other end was. So not perfect by any stretch of the imagination but best I could manage.

I have also, once, just given up trying to gland it and wrapped SA tape around the cut armour. Pretty rubbish but you can only work with what you have.

Pahaha, thanks for the replies and humour lads ;).

@APE37 - The other end of the SWA can be earthed no problem - terminating in a large cupboard next to the meters.

@Ian1981 - Didn't think of glanding into a box within the wall. Assuming there would be no (reg) issues with this box being buried and inaccessible? However, if this is ok, why even terminate into a box as opposed to glanding in the wall as there wouldn't be any electrical connections anyway?

@PEG - The CU is an MK 3rd amendment if that helps?

Missed this post as I was replying to the others! I think you've answered most of the questions I had about glanding into a box. However, what purpose does the box serve as opposed to simply glanding in the wall?

To my mind glands should be accessible for inspection and maintenance. Cables should also be properly secured and arranged so that no strain on terminals is caused.
