2. Choose the right size
Of course, the correct size of the waterproof box is first based on the size of existing components and the location of the equipment to be placed. However, we should also consider whether new components will be added in the future, and if so, whether there is enough space for them. In addition, it should be noted that the reference dimension provided by the terminal box supplier is the external dimension or the internal dimension. It should also be noted that the installation space is usually smaller than the internal size provided.
