The material selection of meter box and small power distribution units usually considers safety, durability and protection. The following are several common meter box and small power distribution unit materials and their characteristics:

Metal (usually steel plate): Metal meter box and small power distribution units have excellent durability and protection, and can effectively resist external impacts and protect electrical equipment. Steel electrical boxes are typically used outdoors or in environments that require additional protection.

Plastic (usually engineering plastic): Plastic meter box and small power distribution units are lightweight, non-conductive and suitable for indoor use. However, its impact resistance may be poor and is suitable for general use.

Stainless Steel: Stainless steel meter box and small power distribution units are corrosion-resistant and suitable for use in humid or corrosive environments. It also has higher durability, but costs more.

Glass fiber reinforced plastic: It has good corrosion resistance and insulation properties, and is suitable for some special environments, such as chemical plants or coastal areas.

When selecting the material of the meter box and small power distribution unit, it needs to be evaluated based on the specific use environment and safety requirements to ensure that suitable materials are selected to improve the life and safety of the electrical equipment.
