Soldering tails

Don't you like that? I love it.

A brass furrel. I just looked in Wiki and it's like a brass monkey but it lives in your trousers.

I've got a ferret hanging up my nose How it got the no one knows .....

Thanks, but I'm looking for something more definitive than word if mouth though. Anyone?

I have been having a problem with evening september, that's the reason for multiple responses.

[ARW]

"evening september"?

[Bill Wright]

Why would a link to some dodgy website provide more authoritative information that you can get here?

[John Rumm]

As harry would say, "bollix"

I find it difficult to assess the correct torque on a terminal screw, for being brass or copper alloy I am concerned over shearing the head or one side of the slotted head.

One issue is that heat through contact resistance will temperature cycle the terminal leading to a further loosening the grip, and increased resistance.

[Fredxxx]

LOL - that's the best excuse for giving eveningly wrong answers.

[Dave Plowman (News)]

If you use a screwdriver with a blade the same width as the screw head, you can make it good and tight.

Have you ever sheared a screw in a terminal? Can't say I have, and mine don't come loose.

[Tim+]

I didn't specify a "dodgy website". Clearly the consensus here is that it's a bad idea. I just thought that if this is generally agreed, there might be some sort of authoritative directive from a respected source saying "thou shalt not solder tails" (or words to that effect).

A lot easier (and more convincing) to post a link than to copy and paste a bunch of anecdotes.

I'm not surprised if that's what you are trying to use.

Eternal--- septober.

I was taught that at the Pye factory where I started work but only to hold the ends of the strands together, the screw went onto the unsoldered copper wire part....

Crimps..

Thats the best method, decent crimp pliers, ratchet ones a must:)...

BS7671 17th Edition

526.02

"where a soldered connection is used the design shall take account of creep, mechanical stress and temperature rise under fault current conditions"

Which while not exactly on topic, does imply that one must allow for creep when using soldered connections.

(also keep in mind that when clearing a fault, on a circuit already at maximum design load, the final conductor temperature could be 170 deg C

- one would not want solder tinning relaxing at just the wrong moment!)

[John Rumm]

Yeah, his memory is responsible for the content of those multiple responses.

I must treat myself to a pair of these, having just made 32 crimps by "hand" (two sets of V8 ignition leads.)

[Bill Wright]

No but you might get one. How can you tell? Even the most respected names sometimes emit bollocks. Look at Global Warming. If you believe everything the 'definitive experts', the IPCC, say you would be led right up the garden path.

You have here in this group people with many years practical experience and no axe to grind. What could be more authoritative, in reality? You would prefer something written by a kid who's done a few tests in lab conditions but happens to work for a big firm?

These ones are fine, the cheaper version without the heavy jaws and ratchet are useless...
