My point about the powder coating is exactly what your reply was.
I didn't trust an insulating substance to act like a conductor in the event that somehow your box became live without tripping your rcd.
Genuine question not sarcastic:
So are you saying that there is no way that voltage or current at dangerous levels could get to you through the pot?
We are all here to learn.
Current is the killer! 30mA is the level at which it affects the human body, causing the heart to go into arythmia (especially if you receive a shock from one hand, across the chest & exiting through the opposite hand). This is why most RCD's are 30mA units. Hospitals have 10mA units.
An RCD senses out-of-balance current so if the current flowing in the active & neutral is not the same (by 30mA or more) the RCD trips. We can assume if it is out-of-balance then it is flowing to earth somewhere. If your RCD is installed correctly your box will NEVER become live, it's just not possible.
I am lucky in that I have RCD's in my home as well as having fitted one in the box (if you have them it's a good idea to give them a function test monthly or better still, an injection test 3 monthly if you have a Sparky mate with the correct tester :handgestures-thumbupleft: )
