Connect the equipotential terminal box to the ground flat iron. Can I use plain flat steel?
Equipotential terminal box is the protection main buildings, water gas pipes, heating and refrigeration, cooling system, link building components such as metal parts, in order to meet the anti shock protection requirements of the electrical contact voltage of less than 50V. Is an important component of modern building electrical appliances, is widely used in high-rise buildings.
Specification requirement is 25*4 or 40*4 hot galvanized flat steel, said the family specification is also very reasonable, even galvanized flat steel, long time buried in the soil or on the floor, the wall will be laying, easy to rust, if we use the normal flat iron, not to mention that, certainly rust, but the speed is much faster than galvanized flat steel!
Connect the equipotential terminal box to the ground flat iron and cannot use plain flat steel. What level of ground steel must be used in AC electrical grounding standards, and must be hot-dip galvanized flat steel, the first is corrosion protection, and the second is long acting. Whether or not galvanized is always corroded, all national standards, industry standards, local standards are required to use hot-dip galvanized flat steel. And, depending on where it was buried, the size of flat steel was decided.
