Why does the indicator show voltage on two wires?
Tell me please. I connect the LED bulbs. I am testing with an indicator where the phase is and where is zero, the indicator shows in both wires that the voltage is in two wires. When I turn on the switch to turn on the light is on. I'm testing the wires again, when the light is on, the indicator shows that there is voltage in only one wire. Is it correct? And what could it be connected with? Could this affect the amount of energy consumed by the house? If so, how can this be eliminated?

The presence or absence of voltage is checked with a voltmeter or multimeter in the voltage measurement mode. The indicator can show the so-called “tip” from other wiring lines, in reality there is no phase on this wire. It’s generally not clear where you are checking with the indicator. If you check the indicator on the lamp when it is turned off and the indicator shows two phases, then you probably connected the phase to the lamp, and zero goes to break by the switch and thus on the lamp shows two phases - the phase that goes from the wiring to the lamp and through the lamp on the other wire the same phase shows. This does not affect the amount of electricity consumed. In reality, you do not have two phases, since two phases are a linear voltage of 380 V, at this voltage all electrical appliances will immediately fail.
