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

I work through agencies, so unless the company I’m working for supplies them, I’m not going to.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.
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.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.
For Rob I was just messing with you MateI knew Rob, jus
I always put a ferrule on fine stranded conductors

I have a lad working for me at the moment, and he had never been told to use them in his training, but agrees with me they make a much better connection.
Anything that improves a connection is better practice. But more so, anything that improves the "longevity" of the connection is good practice. I got into the habit of "tinning" using solder - fine stranded conductors. Yes this is time consuming, most likely OTT and probably unnecessary for most applications but it ensured a very good reliable connection.
Tinning should only be used with very specific applications.
Edit: Although I do remember the days that tinning joints was common practice. Terminals and connectors aren't as good quality as they used to be. An it was before the widespread availability of ferrules and insulated crimps/ related tools becoming cheap.
Chop a couple strands off to make sure they fit properly............ ;o))))Do you twist meter tails or untwist and give them a little squeeze to square them off?
