There are many reasons, such as the wrong connection of the zero ground wire, or the simple loose zero wire, the interface is not firm, and the virtual connection is false. This causes the power strip to be plugged in, and the red light is bright (some patch strip indicators will become less bright, but will still be on), creating the illusion that there is electricity. And after plugging in the appliance and there is no response, if you judge that the appliance is broken, let the repairer come, it will be a waste of time and money.
Instead, you should try an appliance that you can find at hand, such as a hair dryer or kettle, and you will find that all the appliances are not working. At this time, let the electrician handle it, find the point where the neutral wire is disconnected (usually the interface of the circuit breaker or socket) and re-tighten it.
It may be that the plug of the hair dryer is not in good contact with the socket, or it may be that the power of the hair dryer is too high, and the wall socket has a high-power protection circuit.
It must be in which link there is a problem, when the power is on, the socket switch has a button that needs to be opened, and the remote control also has a power switch, it is recommended that you use it, carefully read the manual, it is really not operable, you can call the after-sales phone, or consult the service staff of the store.
It should have tripped, just send it yourself, or the wire of the switch box is loose!
Some smart toilets can also automatically flush the water remotely when the power is off, because the lid is equipped with a lithium battery. >>>More
