Knightsbridge GU10 Fire-rated fittings - Loose push connectors - anyone else?

[Pretty Mouth]

Same problem I had with some enlite efd pros a while back, same piano key connector, earth terminals wouldn't grip. If you looked into the terminal holes you could see which ones were going to be a problem. I swapped the connectors for wago 224s.

Wrapping in tape doesn't sound like a solution.

Thank you, gentlemen, for all the advice.
I found that removing more of the outer sheath and having the inner cores enter the connector more perpendicularly, made them a LITTLE less likely to pull out. But it's a cr@p job having singles hanging out of the fitting, then covering them with tape.
I thought about a bit of flex then Wagos in a Wagobox, but I don't have enough boxes here, the shops are shut, and I need to finish this tonight and leave. Not happy about it.
At least it's all LEDs now, so little heat and only about 40mA per fitting so there's no fire risk from any poor terminations.
At eight quid each I'd have expected more. I'm puzzled how such rubbish connectors can be compliant. I won't buy this brand again!

You shouldn't be having basic insulation outside the enclosure. I don't think the connector is at fault, but rather the lack of space in the box.

For only £12 you could have got the KSR QR10 integrated fittings I use with plenty room at the push fit terminals, or even the Enlite E8 which seems very popular.

As stated above, with experience it gets better. After a break at a local bar: a gin Martini, a poncy avocado and quinoa salad (yeah, but this site is in SW1) and things start to look and feel better.
Still bloody awful but there's a work-around: form the cores a little tighter, insert them, hold in place, fix with a well-tight cable tie having discarded the useless clamp and hairpin arrangement. This prevents the cores from dislodging, even if they are not very well clamped.
No loose cores, no tape, and enough to get the job finished tonight, even if I have to do the first few again. It's going to be a late night, but I'm a night owl anyway

Everything's better after a martini. Just remember to not use those fittings again. It's the tiny little things that can end up giving such big headaches.
