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
