How to wire the equipotential in the bathroom?

(1) In the equipotential box of the bathroom of the new house, [no need to] pull another wire to connect with the grounding wire of the distribution box.

Reason: The flat steel introduced by the equipotential box is welded separately on the ring beam steel bar as the grounding body, and is an independent grounding device. The grounding with the distribution box is 2 different grounding systems.

In residential electrical design, it is generally required that a copper wire be drawn from the toilet equipotential box and connected to the socket of the bathroom. It is equivalent to the grounding wire has a double guarantee. If you find that there is not a single copper wire leading to the socket in the bathroom equipotential box, it is recommended to add this wire.

2) When decorating the bathroom, it is recommended to draw out a few copper wires from the equipotential box and connect them with the steel sanitary ware accessories (directly snap with a pipe clamp).

3) The multimeter can only detect whether the grounding wire is connected, and cannot measure the grounding resistance value (Note: as long as the wire is firmly connected to the equipotential box, the measurement is of little significance!). ）。

4) If you want to measure the resistance value, you should use a megohmmeter or a ground resistance tester, if there is a condition, you can measure it, but as long as it is connected, the measurement is of little significance.

The equipotential wire is used for measurement during construction, not the ground wire in the distribution box, the ground wire in the distribution box is set up by the power department for safety, and the ground wire in the distribution box should be used for sockets and lights, not the equipotential wire.

1.Equipotential means that the ground wire and the equipotential position are almost 0 resistant

2.Generally, the ground wire and the equipotential are connected with a very thick metal, such as copper plate, zinc plate, etc. The ground wire and the equipotential of the distribution box are generally not connected by copper wires below the square.
