Does the equipotential of the toilet need to be connected to the ground wire of the incoming power b

Need.

The local equipotential of the toilet is indirectly connected to the ground wire of the entrance box. Because the local equipotential galvanized flat steel in the bathroom is welded together with the steel bars of the floor of the building, and the grounding system of the building is loop-through. Secondly, the ground wire of the socket in the bathroom is also connected to the local equipotential, and the ground wire of the socket is originally drawn from the entrance box.

Therefore, the equipotential of the bathroom is finally connected to the grounding of the entrance box.

Equipotential bonding considerations.

The equipotential is generally installed under the basin and should be repeatedly grounded with the branch socket. In places where wet and dry areas are not partitioned, it is recommended that equipotential installation is carried out in the ceiling. Because the ground is often moist and equipotential-connected.

The flat steel of the local equipotential box should be welded and introduced from the node of the bottom plate reinforcement, and should be welded and connected with the column reinforcement and shear wall reinforcement within the local range.

The importance of equipotential, do not install equipotential, if a person in the bath once the leakage, it is absolutely dangerous, the body surface resistance is too low, the danger before the leakage action is already uncontrollable. Even if PVC water and electricity pipes are used, the socket in the bathroom also needs to be repeatedly grounded according to the specification atlas, and the connection point is in the local equipotential box in the bathroom. The coupling specification is that all exposed conductive metals inside and outside the restroom should be connected to the equipotential, including towel handles.

The equipotential of the bathroom must be connected to the ground wire of the power box in the house. In fact, there will often be leakage accidents in the bathroom, because there is always a lot of moisture in the bathroom and there are often water stains, if you don't deal with it well, it will be very troublesome, then the general measures will be directly installed in the bathroom A local equipotential box, and then connected with the ground wire of the power box, but some people say that this is not necessary, then it is wrong.

There are clear regulations written in the standards for house design and the standards for the acceptance of the owners, which must be dealt with There may be people who don't understand the consequences of not doing it, but they just think that it takes more time to figure it out, and it doesn't feel useful, and even people who pretend to be knowledgeable will say that if the ground wire in the distribution box is connected with the equipotential, it will lead the thunder and lightning to the home on a rainy day, so it can only be said that it is too uneducated.

The function of the equipotential box like the bathroom is actually mainly used to eliminate the voltage in the bathroom To avoid the leakage of the leakage because of what situation there is no way to disappear, it will be easy to cause accidents and even cause harm to the human body, and like local equipotential can be directly connected with flat iron and plate reinforcement, but finally it must be connected with the main reinforcement of the beam and the lightning protection down wire, so as to ensure that the transmission of current is effective.

If you say that you can directly do local equipotential wiring, in fact, all the pipes in the bathroom that belong to the metal nature must be connected to the grounding terminal in the equipotential box, and they must be treated with copper wiresTherefore, either local or total equipotential is used to eliminate the current.

Yes, the ground wire of the socket power box was originally drawn from the entrance box.

This is a necessary measure, because when there is a lot of water in the bathroom, it is easy to cause the leakage effect of electrical appliances.

It depends on the individual's wishes, and if you really want to connect, you can still connect.

This one definitely needs to be connected, but I don't know why.

I think it's still necessary to link to it, so it's convenient and time-saving.

It should be connected with the ground wire of the incoming power box, and you can also ask a professional person.
