Hi all

Curious, what is the compliance level on ferrules?

Follow up question:
Often you have plugs with around 3 or 4 wires all coming into one plug box from various directions.
Most of the installations I've seen just shove all those wires into the plug so they are sort of joined together.

And almost all of them are dodgy (to say the least), eg. bad connections or not well fitting.

What are the options for improving that?
Can you just solder them together and run a wire from the solder joint that goes into the plug (eg. 4 wires soldered together with a with 5th general purpose wire soldered in that goes into the plug)?

Or is there some method that is actually reliable?

Actually generally what is the compliance level of soldered connectors?
