Cable Jointing Practicals for Trainees
In a wireman or electrician lab, trainees prepare a length of multicore cable for a joint or a cable gland. They mark the sheath length with a Tape Measure and score the sheath lightly around the cable. Then they slit it lengthwise with the blade moving away from the body. The cores inside must show no cuts.
Each core is then stripped with a Wire Stripper and fitted with a lug using the Crimping Tool. Teachers should make isolation the first step of every job. The circuit is switched off, locked off and tested dead before any blade touches a cable.
Frequently Asked Questions
What does 1000 V tested mean on this knife?
The handle insulation has been tested at 1000 V. It adds protection against accidental contact, but it does not make it safe to cut a live cable. Always isolate the circuit and prove it dead first.
How do I strip the sheath without cutting the cores?
Score the sheath lightly around the cable, then slit it along its length with shallow strokes away from you. Bend the cable at the score so the sheath parts, peel it off, and check the core insulation for nicks.
Why choose a non-retractable knife?
A fixed blade cannot slide back or fold while you press on a tough sheath, so the cut stays under control. Keep the blade covered whenever the knife is carried or stored.
How should the knife be looked after?
Wipe off cable grease and dust, keep the edge sharp on a fine stone, and inspect the handle insulation for cuts or cracks before each use. A damaged handle no longer gives its tested protection and should be replaced.
