UK Ferules on stranded cable?

[Lm5861]

Looking to make a couple of commando ended extension cables with 4mm stranded cable.
Many say that ferules should be used for this size cable.
Can I get the opinion of anyone reading this thread?
Thanks in advance

I agree to using ferrules.

Thank you

It concentrates all strands to the same point of compression.

Would you say it is a must with this type/size of cable or good practice?

526.9.1 fine wire conductors:

"Suitable terminals shall be used or the conductor ends shall be suitably treated"

Most would agree that ferrules are the most common way of complying with this.

Nothing going wrong for me in 30 years should suggest you don't need them. I do double the flex over though.

Even as thick as 4mm doubled over into a 32a commando pin out?

That you're aware of.

Yes it is best practice to use ferrules with fine stranded conductors in screw terminals regardless of the size of cable or socket.

Some of the screwless terminals are designed for flex without ferrules fitted.

Lots of regulations I don't agree with, but I don't ignore them, ferrules to be used on fine wire and screw terminals (cage clamp ones dont need them)

Good practice but I wouldn't say essential, and I don't think it would contravene any regulation.
