Could be double insulated cable inside, if so, do you think there is a requirement for the pipe to be bonded?
It would be single isolated inside the switch.
Back box/switch would be classed as an exposed conductive part.

I wouldn't have thought it is a requirement if the cable is double insulated and the run has no sharp edges.

But i was assuming the box was attached to the cpc.
do you think there is a need to bond the pipe, assuming the cable comes into the box double insulated?

Personally i was thinking if the flex was secured inside the back box with a cable clamp then the tube need not be bonded, if it is free to move then i think the tube should be bonded.
but I am open to peoples suggestions.
