Stripping for fun,or bending over

[cliffed]

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.

Three words "Fast track training"or "Get Qualified quick"

Most modern "cheap" terminals are not constructed to take a conductor bent over.

They now teach not to do this anymore.

Change of times I guess,always found if not bent over,they can break,especially 1.0mm,even before you screw the switch back.

As an extra: You have 2 stranded conductors, do you twist them together and connect, or twist them singly and connect or strip them and try and get the 2 stranded conductors connected, not talking about flex type conductors.

The title, you did that for effect didn't you.

I don't always bend over, but always strip off, when appropriate.

Can't honestly see what there is to disagree with Baddegg, I simply asked three questions, can you explain the part you disagree with, Question 1,2 or 3?

 

[littlespark]

Never twist two conductors together. Makes it awkward when it comes to separating again for testing etc.

I still bend over conductors up to 2.5mm.
Single cores can break in screw connectors. WAGOs have to be single though.

And stripping cables? I thought the college tool boxes would have proper wire strippers. Using pliers, you can cut through too easily.

For me Pete I was taught method 2 for coarse stranded cable.
Method 1 for coarse stranded cable was likely to damage said cable.

I remember reading a study on termination methods for meter tails, obviously terminated Singly, and there was no difference in the effectiveness of the termination between twisting into a single conductor and not.

Me too, although as an Apprentice I was always told that twisting 2 stranded cable together made the CSA that much largerm thereby filling the terminal up thus making the connection better, soon ditched that method when I finished my Apprenticeship, some 5 years later.

 

[Wilko]

I bend over single conductors up to 2.5mm.
I could've said "I'm a fan of bending over so the screw bites in better, using my favourite tool". But that would've sounded a bit strange, so I didn't.

On that note. 2 x 2.5mm conductors will carry more current than 1 x 5mm conductor.

Yes maybe but only for the 3/4 of an inch, or so, that is shoved in the terminal.

Sorry my point wasn't clear.

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

When I was an apprentice I learned all of these practical skills on site with my mentor, college was where we learned theory.

 

[Deleted member 26818]

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

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.

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.

 

[Moley]

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?

 

[Bobster]

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).

 

[Lucien Nunes]

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.

i have bootlace ferrules on my bootlaces.red for port, green for starboard. still manage to get them on the wrong feet sometimes.

 

[Rpa07]

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.

The ones on your boot or shoe laces are called Aglets.
Not to be confused with a young eagle.

If I had a regs book I would quote the actual reg.

Fine stranded conductors will suffer from copper creep if not suitably terminated.

Twisting and folding over is not sufficient.

So every pendant, click rose and every plug you’ve installed, you put crimps on?

 

[Rpa07]

I think we had the argument/discussion 2 years ago which culminated in a member going out to his van to get a new pendant to prove stranded terminations!
Let it go, let it go la la la la la Dee do!

 

[Bobster]

Take a look at how manufacturers install them.

Why bother putting coloured sleving on wires? Why bother putting labels on a CU? Because it's doing a job correctly.

 

[Deleted member 26818]

I’ve worked in Hospitals, factories, football stadiums, ice rinks, schools, colleges, the O2, railway stations, marshalling yards, offices, hotels, shopping centres, shops, houses, flats, theatres, Police stations, air fields, caravan sites, power stations, data centres, car workshops, resturants and cafes, banks, magistrates courts, leisure centres, swimming pools, the Olympics, street furniture, TV studio, sewage farm, Laboratories, agricultural and horticultural, car parks....
Done power and lighting HV, MV, LV, ELV and reduced voltage distribution, door access controls, CCTV, BMS, trackside signalling, process controls, Fire alarms, PV....

The only time I’ve ever known bootlace ferrules to be used, is in BMS panels at a college and in control circuits at a couple of power stations.

 

[freddo]

I get through thousands of the things, use them on very fine stranded and almost all fine stranded cable. Stock all sizes to 35mm in single, double and uninsulated.

I work through agencies, so unless the company I’m working for supplies them, I’m not going to.

Nearly every power station and sub that I've worked at has been ferruled (that word doesn't look right). Not just control circuits but most auxilaries. I know that all the equipment that I install/repair is fitted with a ferule. Apart from looking neater it makes life so much easier when you have to disconnect/reconnect.

 

[Nebu1a]

Do you twist meter tails or untwist and give them a little squeeze to square them off?

For Rob I was just messing with you Mate
