Trouble a teacher who understands electricity, such a teacher who understands electricians come in

Judging from the situation you described, your problem lies in the lack of insulation between the wall plug-in circuit and the lighting circuit, it may be that the skin of the wire is damaged, but there is no short circuit, at this time, there is a current in the two circuits, that is, there is a circuit in the damaged place, but the resistance in this place is relatively large, (this can be judged from the wall switch, the situation of the switch, because when the wall switch is disconnected, the current can only form a loop through the damaged place, and the circuit resistance in the damaged place is larger, so the lamp is darker, When the wall switch is turned on, the current can form a loop through the switch, and the resistance of the switch is very small, so the light will be on) and it can be judged that the damaged leakage place is connected in parallel with the wall switch.

It is recommended to ask a professional electrician to check the lighting circuit and wall plug circuit for leakage.

1.Pushed on the wall plug and tripped after more than 10 minutes? Answer.

Since it cannot be inspected on site, it can only be judged whether the power consumption exceeds the empty load and causes tripping. 2.Push the gate on the wall plug actually one of the lights in one of the rooms turned on, and the switch on the wall of the room that originally controlled the lights actually became ineffective, if it was turned on, it would be brighter, and when it was turned off, it was just a dark point, and the light was still on.

Answer. You close the wall plug and push the light on the air switch to see if the wall switch can be controlled. Basically, you know what's going on.

The current is, if the voltage is 220V, the power factor is considered, and its active power is the time required for one kilowatt-hour of electricity = 1000 (hours).

Your first problem may not be caused by you connecting the extension cable, I think it is likely that the contact is not good. If you are connected to the power cord well, then you are checking the previous connector, it is likely to be caused by poor contact. If the thread is not in good contact, it is easy to get the situation you said.

Your second problem I'm sorry I don't know how to solve it, but you can replace the air switch in the kind of situation you said, if the air switch is damaged internally, as long as there is a load, then it has to trip, the kind of wiring you said is actually not a problem, but we are not allowed in theory, but it is not so serious as tripping. I think 80% is because of your air switch, I suggest you replace the air switch, hope it will work.

The source of the wires in the canopy is where you find the meter and look at it.

Depressed Such a simple question, you say so many words Are you tired You check the two incoming buses It should be a problem on the zero line I mean there is only a live wire There is no zero line Don't ask me why If you want to explain this, I have to type more words If you don't believe it, you can not use a multimeter to measure, just use a voltage tester Both wires will have electricity.

The kind of persistent pursuit of truth and the kind of landlord.
