1. The total distribution box of electrical appliances should have power isolation, the normal connection and breaking circuit, and short circuit, Electric Components overload, leakage protection. The main distribution box (distribution cabinet) consists of a line unit and a outlet unit, Electric Components or consists of a line unit and a number of outlet units, the installation of visible disconnect point of the transparent plastic case of the total circuit breaker and visible disconnect Point of the transparent molded case split circuit breaker and auxiliary power failure can automatically disconnect the auxiliary power supply type road leakage protection. Each circuit output terminal should be equipped with three-point terminal block.

2. The total distribution box (distribution cabinet) with the number of out of the loop 1 to 5 circuits.

3. Distribution of electrical box consists of a line unit and a number of outlet units, the installation of visible off-point transparent molded case circuit breaker switch and visible disconnect point of the transparent molded case circuit breaker sub-switch and five-point terminal board.

4. Distribution of the distribution box with the number of 2 to 7 circuits.

5. The switch box consists of an inlet unit and a outlet unit, with a transparent molded case circuit breaker and a leakage protector and a five-point terminal block.

6. The total distribution box (distribution cabinet), Electric Components distribution box, switch box visible disconnect point of the transparent molded case circuit breaker should be set in the power into the line side.

7. The total distribution box should be installed voltmeter, total ammeter, meter. Ammeter and watt-hour meter shall not share a current transformer. When installing the current transformer, the secondary circuit must have a connection point with the protection of the zero line, and is prohibited to disconnect the circuit.

8. The total leakage current of the total leakage box (distribution cabinet) should be greater than 30mA, the rated leakage action time should be greater than 0.1S, Electric Components but the rated leakage current and the rated leakage action time of the product should not be greater than 30mA S.

9. The leakage current of the leakage protection device in the switch box should not be greater than 30mA, the rated leakage action time should not be greater than 0.1S.

10. Power distribution box, switch box power into the line is strictly prohibited to use plug and socket to do the activities of the connection.

11. Distribution box, switch box should be the name, use, branch mark and system wiring diagram.
