I'm changing the chandelier in my living room and I would like to double check whether its switch is on the live or on the neutral wire.
I have a test lamp which is rated to measure 125-250V. There are 2 wires coming from the ceiling. When I turn the switch on and test wires with the test lamp, there is light on one of the wires. When I turn the switch off and test again, there is no light.
Does that mean that the switch is on the live wire, as it should be? And does that mean that there is no current in it and it's safe to work on it?
I'm asking this mostly because I would like to work with the wires, without turning off the main fuse.
