Seen that a few times in back street garages. God knows why, but paint sprayers & body shops seem to be the worst offenders

I was lucky on those sort of jobs, I always had a selection of DNO service head fuses & carriers. So it was just plug & play

My Dad is like that. We used to go in an empty house, speculate about calling Norweb to turn it on, and while we were talking he had the lights on with a big fat fuse he just happened to have in his box.

One time - years ago - a Norweb bloke knocked on the door and asked how we had power as he had cut it off three weeks before, and he was the only guy who did that area. We had space heaters drying plaster and concrete mixers going out back for brickies. I said "generators mate". He said "I cant hear them". "Oh they are the new quiet type, pal". He wanted to look, I said "not without the boss here, come back in an hour". When he came back we were in darkness and the brickies were in the nearby cafe. Meter full of fingerprints and no fuse. 

Even the Norweb bloke laughed. The early 90's were fun. Happy days!

There's also a train of thought nowadays that soldering a cable connection can make it too brittle & prone to failure,

I remembered when I was writing that we discussed it once before and you said that. I thought you would pick up on it. 

For me, solder is soft due to lead content, and common sense tells me driving a screw into something semi-solid is better than driving it into something (stranded wire) that will displace under tension even if twisted tight. I did chemistry and physics years ago and I am not buying a solder iron dissipating heat will weaken the structure of stranded copper enough to make it brittle. But I can see a poorly crimped joint will cause resistance and heat.

Don't get me wrong, I am not arguing with you on this, you are more up to date than me on much of this stuff. Why I value your opinion here so much. But we know with regs on all stuff like this (gas is worse) that next month, the EU may decree that soldered wires are better for plugs because XYZ study said so and now it is EU Babble Directive 2098754 and incorporated into the 277th electricians regs.

When I was having a downstairs bathroom done a while back, we had a laugh. I had a spark doing one job and a bathroom guy doing another. The bathroom guy was fitting spotlights in the bathroom. The spark was doing other stuff. Spark commented that the lights in the bathroom were not up to [insert EU babble] spec. Bathroom guy said it didn't matter as the surface above was concrete. They bickered for 30 minutes as the spark said it should be something with a 30 min burn time? Bathroom guy said the roof above - being concrete - was more like 30 HOURS so quit being a pussy as the regs referred to plasterboard and wood. Oh, it went on and on......

Sorry for triple post, but I just remembered this......

A couple of weeks ago, an old chap wandered in and asked for our extra long black flex (we have loads of them cheap with a kettle plug on the end - explained on the site). He wanted it for a DC14. I made sure he knew he had to cut off the plug and make the connections himself, he said he knew that, and he was an electrical engineer in his early days, so no worries...

I gave him the flex, he paid, he then produced his spade ends from his DC14. He asked how we join them on our machines. I said solder and heat shrink. After some babble about how he had few tools since [wife dying/divorce/whatever/I didn't listen], how much extra if we fitted his ends. I said a fiver, he said, "yes please".

A few minutes later he had his black flex with his DC14 ends on. Five quid changed hands.

He then spent about five minutes stood there ogling and caressing the soldered and heat shrunk joints as one would with a 34B model.

To be honest mate, I wouldn't have a clue what the European directive number is. Back in the 90's I was working for a large company & we were having problems with loose plug pins on equipment, the vast majority were plugs with soldered wire ends. The company did it's own National survey & we were told to stop using this method when fitting plugs, then Manufacturers started going away from soldered ends & started using crimped ferrules for the same reasons.

Yes a badly crimped joint can cause heating & breakdown. But compared to the millions of crimped connections carrying current every day, the number that break down is miniscule.
Don't forget: A badly soldered joint can cause serious overheating problems as well & i've seen an awful lot more of those over the years than i have failed crimps.

At the end of the day it's not the termination method that's the problem, it's the way it's applied & the vast majority of people can't solder to save their lives.

As a little aside to the discussion: For Insurance purposes. Soldering even with an iron, can class as Hot work & most PL policies don't cover it. You need to specifically add it to the policy and pay the extra premiums. Likewise if your dabbling / working from home & making a bit of extra money from it, if you have an accident with a soldering iron your insurance may not cover you.

Guess how I found out ?

Anyway don't knock crimped connector s too much, you sell machines with crimped connectors in every day

Yep: No argument there, we had a local guy who was pretty good to me. Might have had something to do with the fact that he spent a couple of months training me  . Used to give me the gear & seal, I'd take all the readings and he'd just fill / sign the paperwork.

By the way: Your bathroom fitter was right, concrete is a bloody good Intumescent barrier in it's own right.

That's an unfortunate thing with any complex regs though, they're very open to misinterpretation.

Well,  i went to the 2 car/hardware stores we have in town,  and nothing.  Even tried the bike shop as its an older bloke in,  and he knew exactly what they were,  but had nothing.  He did have a very nice yellow hoover turbopower 2 as his shop vacuum though.

Bought 50 on ebay for 1.99 delivered in the end!

Also spent some money with mvacs,  although not for anything exciting sadly!

[Madrat]

You know what, I don't even bother looking in town for things like this, always go straight to the web.  sad really.

[beko1987]

I didnt hold out much hope tbh, but my suspicions were confirmed. Left 2 on the counter of one of them so at least theres only 1 more to throw away!

[Tech12]

EBay is where I get most of mine, unless I'm stuck then it's a local Electrical wholesaler at 5 times the price.
Had a good deal on butt connectors the other day,  on the bay again: 100 mixed for 1.48
The other thing it's always good to stock is fully insulated, Right angled Lucars in both Red & Blue.
A good ratchet crimper is handy as well.

You rude boy Inline crimp connectors

Beko:  Forgot to ask what size you bought ?.

[Madrat]

I know that, but I have a carry on mind

I won't ask who's butt you were thinking of connecting to
