Is it necessary to install a surge protector in the household electric meter box?
I believe many people will have such questions. Do you need a surge protector in your home?
Nowadays, in thunderstorm weather, especially under the action of induction lightning, household appliances will still be damaged. Installing a surge protector will also be a necessary choice, which is more conducive to improving the safety of household appliances.
First of all, we need to understand the classification protection of surge protectors:
The surge protector is divided into three levels according to the area that needs to be protected.
The first-level surge protector can be applied to the main power distribution cabinet in the building, which can discharge the direct lightning current, and the maximum discharge current is 80KA~200KA;
The second-level surge protector is used in the shunt power distribution cabinet of the building. It is a protection device for the participating voltage of the front-level lightning protector and the induced lightning strike in the area. The maximum discharge current is about 40KA;
The third-level surge protector is applied to the front end of important equipment (generally, it can be used as the bus front end of a small indoor meter box). The maximum discharge current is about 20kA.
Therefore, you can choose to install a surge protector with a third-level maximum discharge current of about 20kA in the household meter box.
In the process of choosing a surge protector, families must recognize the brand and learn more about its performance in all aspects. Thor Electric has been focusing on the production of surge protectors for nearly 20 years. Its products have passed the safety inspection of the lightning protection center. Check, keep your home away from lightning strikes, protect home electronic equipment and personal safety.
