Best method for terminating SWA into domestic CU?

[oharaf]

Any suggestions on appropriate/good methods for Terminating SWA into a domestic CU. More and more work is involving external supplies and people are reluctant to have Metal CU (mainly due to aesthetics and cost).

Obviously the SWA Gland nut can hold the SWA to the board and then earth via the banjo, it just seems a little flimsy.

My brother, also a sparks favours using a trouser box, and then drawing the cores up into the board

Why a trouser box?

I sometimes use a 4x4 adaptable box, or run a piece of steel trunking along the bottom.
Saying that, I usually use an MK board with an insulated front and a metal base, easiest way then.

I'd think a through box would be a better choice than a trouser box unless you are trying to terminate more than one SWA.

Err, whats a trouser box.

U box, Y box

Turn your Y box upside down.

As I understand it trouser box is another name for Y box (a box with two connections at one end and one at the other)

I thought that, seems a strange choice to use

Thats the way to do it.

Ditto, another vote for the adaptable box.

I've always know a trouser box to be one of them:

Fergus, what about using a piranah nut? There's an example here.

For what it's worth, I use a galv through box, affixing the SWA to it having ensured the tails are long enough to pass right through to the CU terminals. Then I use a bit of 4mm² GY to connect between the box and the earth terminal.

Last job I had to terminate a SWA into a domestic CU I used a single gang MK metclad surface box with a blank plate. Owner was quite specific that they didn't want anything too industrial looking so a shiney metclad seemed the way to go.....

Could have put an earth from the cu to the box terminal also.
