UK Bootlace ferrules

[John-]

Hi. Bootlace ferrules for consumer units terminations. Yes or no? Multi stranded cables only that is and not for putting rings together (periodic testing issues).

Do you use them?

What about on the tails into the board?

Cheers

For screw terminals yes, for cage clamps no.
I'd like to see the return of two screw terminals, can't say I've ever seen an old wylex board with burnt terminations, even when the terminations were not that tight.

Fine stranded cables, always bootlaced, whatever the application.

Except 13A plugs, they were never designed for them.

As above really. No harm in using ferrules with any type of stranded wire (kind of pointless with single core!), but coarse stranded and cage clamps are OK without them.

The reg's refer to fine-wire as seen in flexes etc and not your bog standard stranded cables so all fine wires must be dressed unless the termination is specifically designed for fine wire undressed.

The only time I have seen bootlace used is when rcbo leads are trimmed down , they do look neater than having all the strands squashed under a screw...

Thank you. Do you happen to know which reg please? I guess it could also Explain why the leads have been left long on the RCBOs in The existing board. They did not have a crimp tool and left the original ferrule on..,

By 'fine stranded' do you mean flexible?
Agree in general but I wouldn't say 'whatever'.
What about lampholder/rose flex?
Although, factory fitted plugs (non moulded), generally, do come crimped, without the 'bootlace', as do lampholder/rose flexes.

If a rose is equipped as standard with a flex then I would assume that the terminal is designed to take that type of cable

You can use uninsulated bootlace ferrules,the 'shoulders' of insulated ones just won't go

I believe I'm right on saying that if you were to take prewired flex out of a ceiling rose/pendant, you'll see uninsulated bootlace ferrules used on the conductors

Also handy for grid switches that have little clearance behind the body.

Mmm.......Rock, about 15 years old.
Not really disagreeing with you, by the way, just, has it been wired to bs standard?

Hager boards used to come with two ferrules for the tails a few years ago.

Wellington bootlace, by any chance?
