There are definitely hidden dangers, if it is fine in other places, but in the bathroom, it will be very unsafe. So it is recommended that you fix it, if it is really difficult to repair, you can bring an outlet into the bathroom from somewhere else.

Can't use, ah, if the surface of the appliance is not insulated, it will electrify, pay attention, 10 million.

The purpose of some ground wires is mainly to prevent interference and improve the radiation efficiency of radio waves. If the wire is not grounded, there is an implicit safety hazard that may cause people to be electrocuted. And the ground wire is not necessarily connected to the true earth, but is often connected to one of the input power lines (usually the neutral wire), and its potential is not related to the earth potential.
This is designed for the whole circuit, with a voltage of 0V on the ground wire, to unify the potential of the entire circuit.

It can be used, but Jianyi still has to connect back to the zero line, and now if you connect it like this, it is equivalent to directly connecting the load to the protective ground, and there is no grounding protection.
Disconnect the wires under the bathroom circuit breaker and measure the insulation of the L, N, and ground wires with a multimeter, and then open the sockets one by one to check.
It's better to walk the root line alone.
The power you are talking about is relatively large, which is a large power consumer, and bath bombs and water heaters are more power-consuming. >>>More
How can the socket not have a zero line? Lack of ground wire should be a common occurrence. The neutral line can be shared, but in the case of single-phase power supply, it should be considered whether the cross-section of the neutral line can ensure safety.
The working principle of the circuit breaker: the current of the phase line is equal to the return flow of the zero line, if it does not wait, it will trip, for example, a part of the electricity is taken from the ground when people are electrocuted, and the general bathroom of the building is set up with a separate circuit, that is, two circuits with the living room.
This cannot be guessed, and the instrument must be tested and confirmed.
