Can anyone tell me what size bush and lock ring you need for 4 25mm tails and 16mm G/Y? For a snug fit

Or is there a 3phase tail gland out there?

Wiska do a TPN tails gland, think the one you want is 50mm. They do either plastic or metal.

Ive not seen one that is all combined but you can get a 4 way gland and put the earth in its own gland.

Wiska one has a smaller hole for the earth through the middle. If the enclosure is ferrous I'm sure the requirement is to bring the cpc through the same entry as the live conductors.

Bringing all 3 phase and neutral through the same gland/hole. CPC can be different gland/hole.

Edit: I'm going to hold my hand up on the above. Be a man, don't delete it.
Just read 521.5.1.
I was wrong.

So would terminating the earth onto a through bolt on the DB and then having another earth terminated on the other side be suitable?
