Does household lightning protection use 220V or 380V?

Modern people are increasingly aware of the importance of safety, whether it is personal safety or property safety. In short, security is a very important factor in improving happiness.

Since engaging in lightning protection products, an occupational disease has been committed. No matter where you go, look at whether others have installed lightning protection modules, signal lightning arresters, and lightning arresters are difficult to see at any time, but power supply lightning protection can basically be seen, such as each Every household has an empty box, and only one circuit breaker or air-opening is installed in one of the plates. There are few lightning protection devices installed. For example, in various lighting circuit boxes in shopping malls, there are also few lightning protection modules installed.

But does the family need to install lightning protection products?

After reviewing the information, households are also required to install. The general developer will install a lightning protection or total power lightning protection box at the main power supply of the whole building, while the floor power distribution cabinet will be equipped with secondary lightning protection products, and finally to our domestic households, install the terminal lightning protection device. Someone will ask, how do I choose a lightning protection module? There are many varieties and models of lightning arresters. How can we choose the right products?

Generally, the households are powered by 220V, and all the circuits in the home are illuminated by 220V power supply. Therefore, you only need to install the 220V lightning protection module, or install the lightning protection box directly. The product is generally up to 40KA, enough to protect the home. Even if there is a real lightning strike, I believe that some developers have installed a second-level or first-level lightning protection for a while. The installation method of the 220V lightning arrester is also simple, only need to be connected in parallel, and the grounding measures should be done well, because the lightning protection is mainly relied on the grounding discharge. If the grounding treatment is not good, it is not very useful to install lightning protection.
