Household distribution box role has the following 5 points: 1, Leakage Protection Role 2, over-current, overload, short-circuit protection role 3, over-voltage and under-voltage protection role 4, distribution role 5, switch role

1.leakage maintenance role:

when electrical leakage or line leakage, leakage reaches the leakage protection of the additional value, it will trigger leakage maintenance function, leakage maintenance is secondary to maintain personal safety, prevent the outbreak of an accident. Distribution box is a very important maintenance function.

2.Overcurrent, overload, short-circuit maintenance role:

when the electrical appliances or circuit problems, perhaps when the electrical overload operation, when the electric current reached an additional maintenance value, an overcurrent or overload or short-circuit maintenance function is triggered. This function is used in minor cases to prevent the occurrence of a fire due to overcurrent or overload or short-circuit. This is also an important maintenance function of the distribution box.

3.Overvoltage and undervoltage maintenance:

(1)  When the zero line is broken, the zero line contact is not good, the wind touches the stranded wire, the wire equipment is worn out, the electric appliance increases sharply, the phase line uses electricity unbalance aggravates, the Thunder and lightning enters and so on, maintaining a high or low voltage supply, can reach 450V,  can reach 0V. (2)  And household appliances have a range of voltages to perform normal tasks. Within this range, household appliances can perform normal tasks without increasing their service life, and go beyond this range, maintaining can burn out electrical appliances and may affect their lifespan. (3) . When the supply voltage reaches the extra maintenance value, it will trigger the over-voltage and under-voltage maintenance function. The main function of the over-voltage and under-voltage maintenance function is to maintain the safety of home appliances. Four. Today’s distribution boxes simply do not have this function.

4. Distribution function:

(1) nowadays, all households supply electricity independently according to their households. There are two or three wires connected to the distribution box. (2) distribution function is the minor distribution of electricity power, (3) a power supply line entering a household is divided into several lines through a circuit breaker, (4) for the use of lighting, sockets, electrical appliances and room electricity, (5) to facilitate the switching of an arbitrary line, when an exception occurs, easy to investigate and maintain, will not affect the family other central electricity.

5. Function of Switch: there are many switches in the home distribution box. There are main circuit entry switches and some wire switches. These switches can control the home power lines.
