1, the construction power distribution system should be set up a general distribution box, distribution box, switch box, and form a three-level distribution mode.
2. The installation position of each distribution box and switch box of the construction distribution system should be reasonable. The main distribution box should be as close as possible to the external power supply of the transformer to facilitate the introduction of the power supply. The distribution box should be installed as far as possible in the center of the electrical equipment or the load is relatively concentrated to ensure that the three-phase load is kept flat. The position of the switch box installation should be set according to the situation of the site and construction.
3, to ensure the temporary power distribution system three-phase load balance, the construction site power and lighting power should form two power circuits, power distribution box and lighting distribution box set respectively.
4, all the electrical equipment on the construction site must have their own special switch box.
5, all levels of stainless steel distribution box box and internal Settings must meet the safety regulations, switching appliances to indicate the use of the box to be unified number. Stop the use of stainless steel distribution box should be cut off the power, lock the door. The fixed distribution box should be set up fences, and there should be measures to prevent rain and smashing.
6, stainless steel distribution box is generally used for household use, and the distribution cabinet is mostly used for centralized power supply, generally industrial electricity and building electricity, stainless steel distribution box and distribution cabinet belong to complete sets of equipment, stainless steel distribution box belongs to low-voltage complete sets of equipment, distribution cabinet belongs to high pressure and low pressure.
