D.I. tails entry to c/u.

[Soulsurfer]

Hey all, regarding the entry of d.i. meter tails into a consumer unit I was called to a recent job to quote for a few alterations and people have just moved in, informed me just before they bought that new consumer unit had been fitted etc.. all looks o.k. but meter tails and main earth have been brought in through a 32mm compression gland / rubber packed, and all t & e's through opened knockout and just grommet strip on top of casing. I am doing a new unit on another job soon and local dno are saying just a standard plastic gland is fine ! I'm thinking what's the point of say Wiska sprint metal glands made for Amendment 3 or intumescent sealants if the dno is saying don't need to ? Those glands aren't cheap and customers want cheap as possible of late !

Rather not leave my work open to problems if not maintaining non-combustible ratings, any opinions ?

This Ammendment 3 crap with metal enclosures is all down to the quality of the product lowering over the last 2 decades coupled with the training standards of those fitting them been lower, CU fires was a rarity tbh pre-90s and the boards were made out of wood quite often.

Cu fires are still a rarity except for London if they used the national stats in their presentations instead of the LFB ones they would not be able to justify the amendment 3 change. The product worked the quality of those is installing is what has changed IMO

This Amm'3 is just a knee jerk reaction to try pick up the pieces of relaxed regulations and lowered educational standards, so on that note, as long as the cables are suitably clamped and the terminations tight then a compression gland is fine, btw the Nylon glands are fire resistant and low smoke too so I cannot see the issue.

These new Amm3 glands are jumping on the fear wagon of all the confusion about what is required so yes I agree, what is the point in these metal glands.

It's a knee jerk reaction that has got a lot of people acting like headless chickens

Trouble is the difficulty people have understanding the spec of the different materials available not helped by the IET and the manufacturers peddling a metal only attitude

A pencil going through a sheath can have long term consequences.....

...especially if you're wearing it at the time.
