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.
