When choosing a small power distribution unit, you need to pay attention to the following matters: First, make sure to choose products that meet national standards to ensure safety and reliability. Secondly, select the appropriate specifications and sizes as needed to ensure that the required meters and related accessories can be accommodated. At the same time, consider the material and protection level, and give priority to waterproof, dustproof, and corrosion-resistant materials to ensure that the small power distribution unit can operate stably in various environments. In addition, considering the installation method, you can choose wall-mounted, buried or column-based installation methods that suit actual needs. Finally, choose a manufacturer or supplier with a good brand reputation and after-sales service to ensure product quality and after-sales protection.
