Cable Stripping Method?

Whats wrong with that at 14.28?

That's how every electrician I have seen does it, although some like to leave little nicks in the inner cores insulation and often show copper but hey - they are the qualified electricians among us so it must be right yes?

How do you strip 2+e?

Personally I have found the "cheesewire method" to be both fast and avoid the risk of insulation damage.

Isnt that common practice for stripping T+e? :grab cpc with pliers and use it as Plugwash says like a cheesewire.

When playing at electricity in school, we used these-

The were brill.

A link to a video made by someone so thick that they think it needs music added.

To be honest i find the auto strippers easy, quick, neat and reliable, also i can get in pretty close to the gromit or whatever without the risk of pulling on the cable or smashing my knuckles.

I was always taught that is the wrong way to strip the cable, as you can stretch the cpc. Better to use a stripping tool or go down the middle with a blade - old school I know...

In 45 years of sparking I have never seen stretched cpc, I am a fairly recent convert to auto strippers though especially on panel work

A 1.5mm² cpc stretched to 1mm² is smaller in diameter by about 0.25mm.

Not sure that you would be able to "see" that.

It would, though, then have to be longer which might be noticable.

I have just tried it with 1mm² T&E and it did end up about 1mm longer stripping about 200mm.
0.5% difference; 1mm² becoming 0.995 mm² - assuming it is made that accurately.

I then tried just pulling the CPC and got about another 2mm.

Both could, of course, be the CPC simply sliding in the cable.

So, I don't think it is worth worrying about.

I have used the above style auto strippers, but they grip the cable and rip the insulation off on 2 sides.
I much prefer the ones that are like:

These grip the insulation then surround entire wire insulation and cut it completely around, not just ripping it off.

I work with fibreglass covered 1.5mm mainly and nothing else strips them as well as the ones I linked to. On 1.5/2.5mm 3 core flexible cable I use a
one of these:

Which took a lot of fiddling to get it set right so it did not pierce the outer enough to cut the inner wire insulation, it now works quite well, it would work better if I sharpened the blade lol.
The previous method of scoring with a stanley knife (without cutting the inner insulation) was just too risky and meant I always had to wear a cut proof glove on my left hand which was a pain.

For twin and earth I do similar to the video but use all three inner wires so as to lessen any impact on any single one, I have yet to see a tool that strips the outer off twin and earth (I'd like to though - something else for the toolbox).
I have never, in 30+ years of working on all sorts of electrical equipment seen any negative effects using these methods, I have though seen them when someone yanks too hard and pulls a sharp bend in the inner cores or uses side cutters to cut round the outer sheath and they cut into the inner insulation exposing copper (this is usually how I see electricians do it btw).

The electrician in the video treated the cable like sh*t; ripping the CPC through the sheath weakens and kinks it. I don't treat cable, equipment or tools like that. Cut down the centre of both flat sides with a knife, score lightly around the sheath's circumference where you want it to break, then peel the sheath away like a banana skin. Takes longer but I don't care.
