Equipotential connection terminal box is applicable to general industrial and civil buildings electrical device, in order to prevent indirect electric shock and grounding system failure caused by the explosion and fire prevention of equipotential connection, etc, can effectively prevent building electronic information equipment overvoltage caused by lightning protection system failure and damage to the interference of the accident.

Equipotential connection terminal box such as high-rise residential buildings, hospitals, pools on the steel, the panel of the PE wire terminals, sockets, pipes, heating pipes, gas pipes, metal tub, bath, shower, bathroom handrails, refrigerators, air conditioners, conductive metal floor network will be connected to their respective equipotential connection terminals in the terminal board, which constitute their equipotential body, protect people and equipment safety.

Implementation method:

Inside the toilet will be all kinds of metal pipes, structure (including in reinforced concrete floor) and into the toilet inside the line of sight, with not less than 4 was copper core, through the equipotential connection terminal box connected with each other. Equipotential connection wires on the floor or wall in dark apply to wear plastic pipe protection, its purpose is to replace wire is convenient. Equipotential connection within the scope of the metal pipe and other metal body and equipotential connection box resistance between terminal row should not be greater than 5 Ω. Toilet inside the metal pipe joints generally do not need to add jumper, if discover the conduction, it should be a jumper. When the water pipe is plastic tube inside toilet or plastic coated metal bonding jumper can be pick up on the water taps; Use a metal pipe, jumper directly on the pipe. Between the sewage pipe in the bathroom with the inlet pipe is blocked, so the sewage pipe will be equipotential connection, etc, and also can pick up on the floor drain pipe.
