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.
This was a big failure for me with Lead tin solder ...
as it creeps slowly -crushing under "Just Screw" contacts.-
Plug tops ..with less copper strands in fingers! ==FAIL
..May be a different story with lead free...
(but I've wasted enough time in the past --to want repeat mistake again )
-----NOOOOOOOOOOOOOOOOOOOO----
(may get away with sprung contacts -and alarm/entry "washing line"--
as a BT engineer described it)
 
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.
I've still got that book.
 
The one thing most of you have missed is this. Without going into to much detail, but the physical electrical conductor in use into today is not the same as it was 20/30 years ago. The % copper vers aluminium excluding other materials is not the same. Back then you could, if you wish, bent the conductor in three. But today if you bent it, it cracks.
 
These are the regs regarding fine stranded conductors...

526.9 Connection of multiwire, fine wire and very fine wire conductors

526.9.1 In order to avoid inappropriate separation or spreading of individual wires of multiwire, fine wire or very fine wire conductors, suitable terminals shall be used or the conductor ends shall be suitably treated.
526.9.2 Soldering (tinning) of the whole conductor end of multiwire, fine wire and very fine wire conductors is not permitted if screw terminals are used.
526.9.3 Soldered (tinned) conductor ends on fine wire and very fine wire conductors are not permissible at connection and junction points which are subject in service to a relative movement between the soldered and the non-soldered part of the conductor.
 
I poke em in tighten up. Then tighten em up a few days later. Might even pop back in few months later and tighten em again. Might make it a yearly thing.

Really. You lot have been reading too many IET comics.

I tried popping back to one of the Banks I’d wired, just to double check everything in the vault.
