Third level distribution box: refers to the final junction box of each electrical appliance, which can be movable and fixed. Generally, first level distribution does not allow direct use of electrical equipment, and second level distribution will be by power equipment because it is three-phase electricity, while third level distribution is mains electricity (220V). Below is a brief introduction to the main differences among these three types of distribution cabinets:. That is, a distribution electric box is arranged under the general distribution box, and a switch box is arranged under the switch box, and electrical equipment is arranged under the switch box to form a three-level distributio...
