flex in a FCU should be ferrules. go stand in the naughty corner.I double over if it's obvious the conductor will be small in a terminal....I.e, a single 2.5 in a socket, a small 0.75 flex into a spur etc...
I always aim to get the best possible connection between the terminal and the conductor itself.

Yes i think thats a good guide that i have always followed, but with the use now of the torque screw drivers i wonder if that will change.i usually double if only 1 conductor in the terminal . if more than 1, then i don't.
Unless the terminals are designed to accept fine-stranded conductors. The old MK FCUs with wrap-around screws with captive washers, for example, were specifically designed for flex and could not be used with ferrules.flex in a FCU should be ferrules
There were occasions during my Apprentice days in the 1950s early 60s when I was taught to bind larger conductors with a core of the said conductor when connecting say as an example a 7/064 into a terminal designed to take a larger conductor, just thought you would like to know that piece ofI always make sure the terminal screw closes down on 2 surfaces, spreading the force. Either bending over a single solid core, or 2 unbent.
Fill up the terminal hole as much as possible.

Not really Sparkes' then?I always fold over a single cable , it was how I was first shown
but I have worked with loads of newer day sparks who don’t bother folding over cores

Did you tin the conductor prior to connecting?I have been wrapping tails for years it prevents the conductors shifting. This is a 35mm bond I recently did, wrapped and you can see there is no shift and that is as tight as it goes.View attachment 55570
Why not? ? ? ? three wordsI would say don't tin it if it's going to be clamped with a screw fixing.
No, no tinning.Not really Sparkies then?
