SWA questions, doubting electrician

[LeeH38]

I take it that's under the consumer unit? If so I very much doubt it will reach to redo this with a correct gland & banjo without either renewing it or a join or isolator of some kind.

It is. There is some excess cable under the kitchen units in the next room.

I wouldn't be glanding with banjos (or earthing nut) in that plastic CU, anyway. It requires a metal adaptable box fitting below the unit. Swa glands in plastic.....horrible!

"REQUIRES" is a strong word.
I would prefer to make off into a metal enclosure but if the cable is supported correctly, a plastic enclosure can be glanded off correctly with either a banjo or earthing nut.

A steel through box is another good option, it has an earth terminal in it already to make the connection to the armour nice and easy.

Depends how you take it...in my view it does require it, taking into account those flimsy plastic units.

A well supported swa cable, adds no strain to the enclosure. In some ways it makes it more rigid.

in the OP's case, the installer has cut big holes in bottom of CU, so a through box is required here. 1. to gland the SWA, and 2. to restore the IP rating of the CU.
