Stripping for fun,or bending over

cliffed · Feb 8, 2019

wondering what’s being taught in college these days,to the apprentices.
Cause when they come on site,they certainly aint being taught like us seniors were.
Eg stripping of conductors,many use pliers or side cutters,they do not bend conductors over,up to 2.5mm.
Conduit skills to be admired from a distance.

I prefer stripping with my cable croppers rather than pliers or side cutters.
I only double over fine stranded cables.

Sorry my point wasn't clear.

The ccc of 2 x 2.5mm conductors is greater than 1 x 5mm conductor.

I knew Rob, jus

I always put a ferrule on fine stranded conductors

What sort of theory were you taught at college Dave just asking for a comparison from my time. I did Electro Technology ( from a book that was referred to as HUGHES by the lecturer, Regulations, Maths, Mechanical theory, crikey memories.

So that’s where you picked up all your bad habits then.

Here y'are……... a bit of skilful stripping and bending for you...…..for fun.

Was a bit disappointed with this thread considering the title until I got to this post. Phoar.

AC theory, three phase, basic motors and generators, cable calculations. Some regulations and suchlike. Basic fault finding and inspection and testing.
There was quite a bit if health and safety and some 'key skills' nonsense forced on us which was basically maths, English and computer skills.

I've been a bender for most of my career. I started off straight but got introduced to bending at quite a young age and never looked back. Now, as for cables, well that's a different story

For fine stuff I usually stuff a ferrule on.

Is that a Welsh make of condom, sheep strength?

Fine stranded conductors must have a suitable ferrule, crimp or in a few specific applications tinned ends when terminating. There's specific regs stipulating that. So by just folding over you're not complying.

Only times they can be terminated "bare" is in dedicated spring clamp terminals that the manufacturer of has specified this can be done.

It's a good book that Hughes.
I'd recommend it to any trainee.
You can pick second hand copies for pennies (last time I looked).

There is no one correct method. It depends on the type of cable, the type of terminal and how the size of one compares with the size of another. A method that is ideal for a screw terminal with a wire protection spring might be unsuitable for one without, and vice versa.

There is a lot of detail in the craft of making connections that seems to get overlooked amongst all the complexity of modern electrical equipment. People have forgotten that a bad connection doesn't work, or overheats, just like it did a century ago. There's no magic technological solution to high-resistance joints.

I love having to use shoelace ferrules. It brightens my day. Truly.

Absolutely! First thing I teach my apprentices is how to correctly terminate, check for tightness & integrity and ensure the cables fold back neatly (sockets & switch plates... etc) a major cause of electrical fires are caused by poor connections.
