The current meter box has a switch installation position. As for where the switch is installed, it can be determined according to the actual use. It does not necessarily have to be installed in the meter box.

The function of the switch is to be used as a device for breaking and closing the power supply, and generally also plays a role of overload protection and leakage protection.


Nowadays, smart meters that are commonly installed are equipped with a meter box when they start to install and replace the meter. Generally, there are two switches in the meter box: one is the incoming switch and the other is the outgoing switch.

Although according to the principle of switch use and matching, the incoming line switch should be a disconnect switch, and the outgoing line is a leakage protection switch, but for various reasons, the two switches currently configured are generally disconnect switches, which can only serve as overload And short circuit protection function, can not play the role of leakage protection. As for what the reason is, I won't elaborate on it here.

Regardless of whether it is a smart meter that can be replaced or a new smart meter is installed, the meter box and two in and out switches are usually provided when the meter is first installed, which means that there are switches in the meter box in the early stage, and the switches in the meter box in the later stage. If there is damage, do you want to install a problem in the meter box, and explain this situation:


Because the first meter box and supporting switches are generally provided by the power supply company for free, if the switch in the meter box is damaged due to various reasons, the question of who is responsible for the purchase has become a focus of discussion.

Because this problem is more sensitive and common. If the switch is damaged and needs to be replaced, the electricity customer may say that the power supply company used to install it for free, but now the power supply company is responsible for the free replacement.

However, for power supply companies, these small switches are generally installed on the user side, and in principle belong to the user's property rights. Only for the first time to facilitate the installation and promotion of smart meters, and to facilitate maintenance and management, the access switch is provided. Because this type of switch is also a vulnerable part, it may not be realistic if the power supply department is responsible for free replacement.
