1.Weld 25*4 galvanized flat steel from the bottom plate steel mesh and lead it out to the local equipotential box of the wall. >>>More
It can prevent step voltage, contact voltage and ground potential counterattack caused by lightning strikes, leakage. "Code for Acceptance of Construction Quality of Building Electrical Engineering" GB50303-2002, the equipotential method adopts the welding of two main reinforcements in the ring beam around the bathroom, the gluten of the toilet floor and the shear wall are welded into a grid according to 600 * 600 and the steel bar of the vertical and horizontal ring beam, and a -25 * 4 galvanized flat steel is welded by the ring beam to connect the local equipotential bonding box TD28 (300mm from the ground) in the bathroom, and the local equipotential coupling box of the bathroom is concealed and PVC20FCWC to the toilet socket box. Washbasin and ceiling keel (embedded bottom box 86 * 86 * 50, 450mm from the ground, 2500mm respectively). >>>More
1. All equipotential boxes are set up for connecting the lightning protection down conductor of the roof, which is connected to the lightning rod of the roof at the upper end and the lightning protection down conductor of the house foundation at the lower end. >>>More
The equipotential box is crimped with screws for galvanized flat iron, which is welded to the ring beam, and is connected to the earth by using the main steel bar and the total equipotential. >>>More
Local equipotential is not required to be connected to the down lead, but must be connected to the total equipotential. >>>More
