cable insulation stripping
Having done just a small amount of electrical wiring recently, especially wiring up light switches etc, I realised it was a right pain stripping the insulation off.
I cut the TWE outer sheath longitudinally with a small pair of pointed scissors, which do a good job without risking damaging the wires inside, but it is not ideal and you can stab your fingers if you are not careful. Then stripping the conductors, I have one of those strippers with two V's that form a diamond and that you adjust with a screw and then twist on the cable and pull. But when there is only a couple of inches of cable its suprisingly difficult to hold the wire firmly while you pull the stripping tool. And the side of my finger was becoming sore from gripping the wire. Then you have to readjust for different size wires, and if you get it wrong you can nick the wire. So I was wondering what tools the pro electrions use to do these jobs ? Cheers, Simon. |

To get the outer sheath of T&E off, I've always used side cutters to cut into the middle of the cable, end-on - in other words, inbetween the live/neutral conductors. Open out the end, grip the earth conductor with the cutters, fold it back on itself and then pull as far as you want. This splits the outer sheath and then just use the cutters to cut it off. To strip the insulation from the conductors I use the side cutters to 'ring' it and then just pull it off. |

Decent pair of side snips. Get at the E wire at the end, hold it and pull to split the insulation to the required point. Open out insulation, snip each side fold back and snip across the back. Then stripping the conductors, I have one of those strippers with two V's that form a diamond and that you adjust with a screw and then twist on the cable and pull. JFGI "automatic wire stripper". I have something very similar to the Draper 55806 rather than the 38275 that uses notched blades. -- Cheers Dave. |

Well, I've got near every type of stripper, and what you say is true. However, for 99% of house wiring stuff the type I gave is ideal - and much better than a knife. If I didn't have it to hand, I'd use wire cutters to strip the insulation, not a knife. The only problem with the type I gave is if space is tight. Like, perhaps, stripping insulation at a ceiling rose with the cables already poking through. The wire you're stripping needs to be at least 2" clear from where it exits a hole, etc. -- *Despite the cost of living, have you noticed how it remains so popular?* Dave Plowman London SW To e-mail, change noise into sound. |

They have tension adjuster for different diameters (knurled screw at the back in the photo). They have no branding but are identical to this photo. Phil |

I have a cracking little pair of stainless sprung-loaded side cutters that years ago got used to cut something too hard and got a chip taken out of one jaw. The nick is the perfect size for stripping 2.5mm and does 1.5mm most of the time. Other than those, I use a Snap-On multitool, one of the ****e crimper designs, but it's never used as a crimper, just the stripping jaws and it's great for its purpose. |

Which is another reason I like the ones I've recommended. With the standard set of jaws in mine, it does pretty well all the common cable sizes I use - house wiring, car and electronic. Of course single strand large house wiring is the easiest to strip anyway. -- *Never underestimate the power of stupid people in large groups Dave Plowman London SW To e-mail, change noise into sound. |
