AM3 Tails Stuffing gland

[Gazthesparky]

I seem to have a run of jobs of upgrading consumer units. Previously I've used 32mm standard stuffing glands for the tails when I have needed to. Although the sealing gland hasn't got specific holes for the tails i find that it seals well.

Anyway I've been looking at the special tails stuffing glands. My wholesaler is quoting alot for the metal wiska type. Looking at screwfix they have 2 plastic types. One is just the gland and one is a kit with a KEM adapter.

The only problem is that they need a 40mm hole and on the wylex boards I'm using have 20/32mm holes. So i would have to enlarge the holes to suit or buy the kit with the KEM adapter. Just wondering if anyone has any experience of these?

Just not sure because they seem massive in size any other suggestions what other people use ?

Cheers

I'd say that strictly speaking you'd only need a proper gland [and ideally additional fixings to secure the tails] on a TT system to negate the risk of the CU casing becoming live should the tails escape from the incomer [Highly unlikely I know]. Although I'll use a decent gland in all cases.

For most boards I do id say it tends to be either bottom or side entry and i use a 32mm stuffing gland. In all honesty I think tail glands are a bit of a con although the griploc one looks reasonable. If it was top entry i would use one to maintain IP4X. I wouldn't want to use a grommet as they aren't the best and they come out too easily. Nothing wrong with a brass bush and lock nut though if IP ratings are maintained.

There is a version of the wiska unit which fits through the 32mm hole and will cope properly with 2 x 25mm and 1 x 16mm

32mm Tail Kit Gland - 2 x 16mm Tail & 1 x 16mm Earth Cables - https://www.tlc-direct.co.uk/Products/WKTKP32.html

Sorry, mate. That only does 2 x 16mm Tails and 1 x 16mm earth. Too small for 25mm tails.

Think Murdoch may have meant these:

40mm/32mm Tail Kit - 2 x 25mm Tail & 1 x 16mm Earth Cables - https://www.tlc-direct.co.uk/Products/WKTKP40R32.html

They have a 40 to 32 reducer included.

Out of interest has anyone successfully got 25mm tails and a 16mm earth through the 16/16/16 32mm glands. Bit of brute force through the gasket might do it if the gland body is wide enough..

 

[Dave OCD]

No but I can get a 16mm T&E through a 25mm gland.

How would you guys ensure earthing for a metal tail gland into AMD3 board; if you dont mind me asking on this thread. Would you provide a banjo and/or fly lead/nut; or scrape off the paint for lock ring ?

Use a star washer/paint cutting washer or else one of those locknuts with the little teeth on them.

Use a plastic gland. There're cheaper than the metal ones, especially the GripLoc ones.

Post 24 still no idea what an AMND3 stuffing gland is. What page of BS7671 should I be looking at for a reference.

I think it's a way of riding the coat-tails of a new reg, in the hope it'll increase sales for new products which aren't really necessary.

Been meaning to load these for a few days I put the tails gland agenst the board to see for size. There's a 20mm stuffer and 20mm coupler just for size reference. The tails gland is massive so that is being sent back and I'm going to go for a 32mm stuffer for the tails.

 

[Pat H]

But you wouldn't get 2x 16mm tails in a 20mm stuffer would you? And if the tails are 25mm?
The only issue with the bigger gland is cutting the damn hole. But the bolt up plate cutters make quick work of it.

 

[Gazthesparky]

Yes I know you wouldn't get tails in a 20mm stuffer they are just there as reference as to how big and clunky the 40mm tails gland is.

I am going to go with a 32mm stuffer for the tails as they enter from the bottom

The Griploc 25mm tails gland is 32mm, is that the one your referring to?
