Can the circuit breaker in the split meter ready board box be omitted? Look at Ruixin's advice!

As we all know, the safety of household circuits is very important. Once the circuits are not handled well, there may be late electric shock accidents, which may cause loss of life and property, so we need to deal with it in this regard. Can the circuit breaker in the split meter ready board box be omitted in that home? Take a look at the suggestions given to you by Ruixin Electromechanical technician!

1、 A circuit breaker must be equipped in the household electricity split meter ready board box

The household split meter ready board box must be equipped with a circuit breaker. Let's think about it. If there is no circuit breaker in the split meter ready board box, this wiring may not be able to connect. Because we can't connect directly from the meter to the room. And once there is a problem in the future, there is no way to cut off the power. This practice is completely inconsistent with the requirements of electrician operation specifications and installation specifications.

Just like our old house, in the earliest days, two wires entered the house and then connected to the electricity meter. Then connect two wires from the lower port of the meter, which are generally connected to the knife switch. This knife switch circuit breaker is wired indoors, which is the earliest method. However, this practice is very unsafe and has almost no protective effect. Because the knife switch circuit breaker is an ordinary isolation, it has no protective effect, only the function of connecting and disconnecting the circuit. It can only meet our operation, but it cannot fail to meet safety protection.

Therefore, my personal advice to you is that circuit breakers must be installed in household split meter ready board boxes, and they should be installed with matching circuit breakers.

2、 Configuration of circuit breaker for household electricity split meter ready board box

It is necessary to talk about the configuration of circuit breakers in household electricity split meter ready board boxes. Let's talk about the configuration of the circuit breaker in the split meter ready board box of the newly-built commercial housing: the split meter ready board box of the newly-built commercial housing is generally connected to an air circuit breaker from the lower port of the meter. Then connect the wiring from the air circuit breaker to the overvoltage and undervoltage protector. Because the lightning protection of the building is in the main box, the lightning protection is no longer installed in the split meter ready board box, so there is no surge protector. Finally, connect the overvoltage and undervoltage protector to the upper port of the circuit breaker of the distribution box in our room. Then, from each circuit breaker of the indoor distribution box, it is connected to each indoor power consumption point in the car, so as to realize the configuration of the circuit.

If our family is an old house, the electricity meter is an independent electricity meter installed in the distribution box at home. At this time, I personally recommend such a configuration scheme: in the split meter ready board box, a general air circuit breaker and an overvoltage and undervoltage protector are also installed at the lower port of the meter. Then we connect from the under voltage protector to the distribution box in our room. At this point, we are required to reconfigure an indoor distribution box. There should be a main circuit breaker and sub circuit breakers of each circuit in the indoor distribution box. If it is a house built by rural people, it is recommended to install a group of surge protectors behind the main circuit breaker, that is, lightning protectors.

Therefore, the household split meter ready board box must be equipped with a circuit breaker, and not just a circuit breaker. Personally, I also suggest that you configure a household distribution box to control each circuit, and install circuit breakers on each circuit, so as to meet the requirements and be the safest. I hope you can adopt our suggestions.
