The functions of household split meter ready board box are as follows:

1. Leakage protection function 2. Over current, overload and short circuit protection function 3. Over voltage and undervoltage protection function 4. Power distribution function 5. Switch function

1、 Leakage protection function:

When the electric apparatus has leakage or the line has leakage, when the leakage reaches the additional maintenance value of the leakage protector, the leakage maintenance function will be triggered. The leakage protection is mainly used to protect personal safety and prevent the occurrence of accidents. It is an extremely important protection function of the split meter ready board box.

2、 Maintenance function of overcurrent, overload and short circuit:

When the electrical appliances or lines show faults, or the electrical appliances are overloaded, when the electric current reaches the additional maintenance value, it will trigger the over-current or overload or short circuit maintenance function, which is mainly used to avoid the occurrence of fire due to over-current or overload or short circuit of the lines. This is also an important maintenance function of the split meter ready board box.

3、 Maintenance function of overvoltage and undervoltage:

1. When the zero line is broken, the zero line is in poor contact, the wind touches the twisted wire, the wire and equipment are old and aged, the electrical appliances are increasing sharply, the imbalance of phase line power consumption is increasing, and the lightning is entering, the power supply voltage will be too high or too low, up to 450V at the highest and 0V at the lowest. 2 ○ Household appliances should have a voltage range in order to work normally. Within this range, they can work normally without increasing their service life. Beyond this range, they may burn out the appliances or affect their service life When the power supply voltage reaches the additional maintenance value, the overvoltage and undervoltage maintenance function will be triggered. The overvoltage and undervoltage maintenance function is mainly used to maintain the safety of household appliances and prevent electrical appliances from being burnt out due to abnormal power supply voltage. 4 Today's split meter ready board boxes simply have no such function.

4、 Power distribution function:

(1) Nowadays, families supply power independently according to the household. Generally, two or three wires are connected to the split meter ready board box. (2) The distribution function is secondary to the distribution of power √, (3) One power supply line into the household is distributed into several lines through the circuit breaker, (4) ◎ It is used for lighting, sockets, electrical appliances and rooms, and (5) It is convenient to open and close one line at random. In case of abnormal conditions, it is convenient to check and maintain, and will not affect the power use of other centers of the family.

5、 Switch function:

There are many switches in the household split meter ready board box, including the main switch of the incoming main line and several trunk switches, through which the household power line can be controlled.
