So here is a head scratcher.
I have a machine running on three phase. L1 L2 L3 N E. (Neutral isn’t used)
So I’ve tapped into L1 and neutral and taken it to a switch. Switch is reading 200v. There is an existing light attached to the machine running on an external single phase supply. My plan is to tap into the machines power so I can get rid of the external power supply for the light. So I did this, I wired the light into the switch. When off I still get a reading of 200v from the input, switch it on and get a reading of 0v. Something is happening to the light that must cancel out the voltage. Maybe an existing circuit that no longer works.
Can’t figure it out. The light is in the depths of the machine so can’t see it.
