Hi nicebutdim,
Please don’t use CHEAP push fit connectors.!
FLEX doesn’t connect well with Push Fit connectors ( hence why we use Feral's ).
Lever operated Wago may perform better.
But Feral crimping is more acceptable.

Ferrules shouldn't be used for push fit connectors.

No it doesn't, SY is mechanically not very good at all. And for that apllication you need good flexibility which SY doesn't have.


Yes it does, it's flexible cable, the clue is in the name!

A decent rubber flex is far more suitable than SY, with the advantage that rubber flex will actually comply with UK product standards.

On my first original inspection of the loft I noticed a number of mice and squirrel 🐿 traps.
There was evidence of 🐿 🐭🐁 activity, so for that reason I over engineered the materials used.

I’m grateful for the lesson, and now understand that Flex, is flexible.

But possibly not as 🐿 tolerant as SY.

Would you agree?

SY cable is not suitable in fixed wiring applications that require compliance with British Standard 7671.

I think we're being trolled. Having said that I've had a few ales. But I can still punctuate with the best of them. Hurrah.

Cheap push fit connectors are supplied with lights linked by OP and can be seen connected in one of the images. I'll eat my hat if ferrules have been used.

In this instance the push fit connectors have a button to release and are perfectly fine for use with flex - it's just that the connectors supplied with cheap light fittings can be hit and miss when it comes to gripping cable.

Thankyou nicebutdim,
I thought I was going mad.

And ferrules can be used with Wago connection units!

I think we’re straying from the point.

Which was:- over engineering my cable choice from PVC or UPVC flex between a loft hinged access light fitting, 1 meter into a loft using 1.5 3c SY as the clients property had an infestation of 🐿🐁.

What would you guys have used???

The indents left by the crimping tool on the ferrule could catch on the leaf spring and cause it to get stuck.

Using boot lace ferrules creates a highly loaded point of conduction in the clamp. This both reduces the current carrying capacity and potentially increase the chance of a poor contact if oxidised. Cage clamp terminals are designed to encourage wrap of the stripped bare cables around the internal clamp contact. This increases the contact area considerably.

I welcome your response, but as a 3c 1.5 flex has over 20+ individual strands within each core, it’s often very awkward to guarantee a sound connection with these lever type push in connections, especially if your daisy chaining 2 inputs on each lever for L N CpC.

As we all know, just one of those annoying strands can split away/across and arc.

Also, you can’t guarantee that the entire twisted strand has fully entered the lever enclosure and not just crumpled up inside.

A further question I’d ask you, is

For what reason we’re Ferrels introduced to the electrical industry.???

Coarse stranded (class 2) cables are the only stranded cables suitable for use with the 773 range.

SY is fine stranded (class 5) and not suitable for use with that range of connectors.

It doesn't matter what we think, the manufacturer is clear on this point.

Very well explained nicebutdim, 👍

Now as much as I enjoyed solder tipping (NOT), I’d rather ferrule and terminate in a ferrule approved connection unit.

OR just hope that by twisting the strands will hopefully be adequate to shove into a lever type block.! And hope for the best.!

Wago lever connectors are fine for used with fine stranded conductors and are designed to apply constant tension without damage to those conductors.

If there is rodent activity then what is required first is pest control.

SY is not in any way rodent proof!

The only wiring systems which are truly rodent proof are steel conduit and MICC.
SWA is fairly rodent resistant but they can still damage the outer sheath which can be an issue if any moisture gets into the armour.
