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.

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 :eek::D:D

For fine stuff I usually stuff a ferrule on.
 
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.

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.
 
i have bootlace ferrules on my bootlaces.red for port, green for starboard. still manage to get them on the wrong feet sometimes.
 
Why can’t I remember that they are called bootlace ferrules, I let myself down each time!

that's nothing.when i was a lad just left school, i went for a job with a farrier, shoeing horses. took me all day to realise that the job did not entail chasing the horses round a field shouting SHOO, SHOO.
 
I wanted to give an ‘old’ but it’s the weekend so you get a funny despite my rolling eyes!

There’s no requirement for ferrules or crimps.
Just for tacking precautions to protect the core when terminating.
Twisting and doubling over is one method.
