There is electricity on the zero line of the spotlight in the living room after the switch is remov

You said a lot, but I'm still dizzy, how should you control the chandelier and spotlights, is it the same power supply from the main electrical box, the box you dismantle should be the switch box, there are two buttons on the switch, right, one to turn on the chandelier and one to turn on the spotlight, and, how can you test the current with an electric pen, you wrap the zero wire with yes, where is the zero line you packed, in the switch? It should be in the junction box of each lamp, there are the following possibilities you check, maybe the zero line of the spotlight is connected in a junction box.

Maybe there is a problem with your spotlight switch, maybe the zero line of the spotlight is leaking to the ground somewhere, your circuit breaker is not protected if it does not have a leakage protection function, this situation cannot be protected, if it has a leakage protection function, it means that the ground wire of the lamp is not connected to the main electrical box during construction.

If the zero line and the live wire at home are reversed, you have to reverse the zero line and the live line of the meter!

There is also a situation that there may be a zero line that is damaged, not completely insulated, and there is a circuit formation, so it is best to find a professional electrician to check! Generally, this situation has to be measured with a multimeter, and the electric pen is not accurate!

Brother, is that because there is a lack of items? Is there a wire that is not connected?

You obviously don't understand electricity. The voltage tester may detect induced electricity; When the live wire is energized and the zero line is broken, the voltage tester also measures the electricity. Or ask an electrician to check it out.

It's very simple, just flip the two wires under your switch upside down. Surely the dark light above is gone.

Are you an electrician, are your original spotlights on properly,
