Technical FAQs 4

What is a 3 level distribution box?

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.

What is a tertiary distribution box?

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.

What is three level distribution?

Three level distribution: distribution box is set under the general distribution box, switch box is set under the distribution box, and electrical equipment is set under the switch box to form three-level distribution. "Two level protection" mainly refers to the adoption of leakage protection measures.

What is a construction power distribution box?

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.
