That's old school Tom! - these days I prefer an earthing nut - much tidier and easier and far better with plastic enclosures.

I find with this arrangement if using an earthing nut, that the earthing nut securing grub screw only just bites on the short threaded part of the S.W.A. gland, as the gland is a bit short for this application. The Wiska box sides are quite thick.
Also, I like to fit the S.W.A. gland body and eathing nut to the enclosure first with adaptable boxes or metal consumer unit enclosures. Then after cable preparation, I offer up the S.W.A. cable and lastly tighten the S.W.A. gland back nut to secure the armour. This way the back nut is easily secured external to the enclosure, and the earthing nut is rock solid.

Just to go back to the OP's actual cable size - he says the diameter of the cable is 23mm - Too small for 2 core 25mm csa SWA surely?
