The point type secondary distribution box consists of a secondary distribution box and multiple distribution box units. The first distribution box unit is connected with the secondary distribution box through the wire cable, the second distribution box unit is connected with the first distribution box unit through the wire cable, and so on, and so on. The other several distribution box units are connected in series. The power distribution box unit includes lighting box. On the lighting box of the product, there are wiring terminals, zero row, 32A 3P air switch, 25A 2p leakage protector, 10a single p air switch, ground bar, 380V aviation socket and 220V aviation socket. The product's point type two-level distribution box can make the temporary power distribution reasonable and safe, and make the construction site more standardized and tidy.

A medium voltage distribution box located between two parts of a circuit to perform at least the functions of current flow between these parts, current interruption between these parts, current disconnection between these parts, and grounding. The box is characterized in that it contains a switch (or circuit breaker) of vacuum breaking technology, which can also be used as a selector; and a selector connected in series with the switch (or circuit breaker) of the product, which has at least two positions, namely, the current flowing position and the grounding position of one of these parts of the circuit.
