Just went to change a one way dimmer to a one way switch and the black wire was in common and red was in L2
I thought red went in common and black in L1 ??
Probably leave it to an expert now as that has confused me
The black one should be sleeved to show that it's a line conductor on a switch line. They are rarely sleeved in the real world.
