I was connecting a cable to a junction box that I had fitted some years back and noticed the terminal screws though secure were not particularly tight which is unusual for me as my torque settings are normally one grunt + 1.

The junction box was fitted to a joist and it made me wonder if the act of walking over the floor at that point was causing enough vibration to ease the screws off? I it is the cause then it certainly makes the case for Wagos.
