I have wired my electric wall fire into the fcu next to it . I twised the stranded wires and secured them in the terminals .

I've been told by a colleague I should be bending the wires over?

If they are fine stranded cables then you should be using a bootlace ferrule.

 

[Dustydazzler]

Bootlace ferrules are not required

Just strip twist and fold over

I would disagree, I think for fine stranded cable bootlace ferrules should be used as often when you tighten the screw terminal it cuts through the individual strands of the conductor even if it is twisted and folded back on itself. Manufacturers have been putting ferrules on fine stranded cable for ages.

You may disagree Tel, but on the industrial plant I work on it is a requirement to use bootlace ferrules to avoid the risk of faults caused by poor terminations.

Hi Derek. What faults can happen?

where did i disagree. just seen it. slipof the sausage fingers, replaced with agree.

 

[derek]

I take back what I said with an apology for jumping the gun Tel.

 

[telectrix]

my fault. i pressed the wrong ---. back to OP what is this word, "scrauded"?

 

[derek]

Hi Derek. What faults can happen?

Faults can range from over heating terminations potentially leading to fire to poor earthing meaning the equipment could be unsafe to use. Or the equipment might simply not work

However, some accessories have (or had) terminals suitable for fine stranded cables, in which case ferrules are not essential. A few types of terminal such as the older MK wrap-around screw with captive washer, as found on their flex-outlet FCUs for many years, were designed especially for fine-stranded and could not be used with ferrules.
