Third level distribution box The three-level distribution box is usually installed inside buildings, such as residential, commercial buildings, or public places. The function of a three-level distribution box is to distribute low-voltage electrical energy to different electrical equipment or areas.
And save wire. The first level distribution box is to introduce three-phase power supply, ground wire and zero wire from the transformer. Class I power distribution box: the construction power distribution cabinet is used for the construction power of the construction site.
In the primary distribution box, various protective devices are usually installed, such as isolation switches, disconnectors, grounding disconnectors, overvoltage protectors, etc. These devices can protect the equipment and wires inside the distribution box from external power interference, thereby ensuring stable power transmission.
The tertiary distribution box distributes low voltage electrical energy to different electrical equipment or areas. In addition, the design and selection of distribution boxes need to consider multiple factors, such as power demand, power load, cable size, rated current of circuit breakers, and so on.
1. The first level distribution box is relative to a building or workshop, which is the first level distribution box of cables directly led from the substation or municipal distribution station. It mainly plays the role of distribution and summary. 2.
It is safe and aesthetically pleasing, and the rainproof top of the box is suitable for outdoor work. A distribution box is installed under the main distribution box, and a switch box is installed under the distribution box. Electrical equipment is installed under the switch box, forming a three-level distribution.
