If you want the electrical box to be used in a normal environment, you should make the following adjustments when you choose it:

1. First, the ambient temperature is generally not higher than 40 ℃ or lower than - 5 ℃.

2. The surrounding environment can meet the pollution level.

3. It is installed in a place where there is no severe impact and vibration.

In addition, the daily life of the electrical box is usually in maintenance, the first thing to solve is its own dust-proof steps. This is mainly because the components installed in it can not directly contact with dust. So we can understand why the sealing is very important when it is made. For the components in the product water, dust is very easy to make it work when the temperature rise and can not carry out the phenomenon of heat dissipation. Further, the components will accelerate the pace of aging, or burst explosion. So dustproof has always been an important step in the maintenance of the electrical box.
