The electrical clearance of the low-voltage small power distribution unit refers to the safe distance between various components inside the electrical equipment and between external components. The purpose of this gap is to ensure proper operation of electrical equipment and prevent arc flash, fire, or other electrical hazards.

Generally, the electrical clearance of low-voltage small power distribution unites should meet the requirements of national or regional electrical safety standards and regulations. These standards generally specify minimum distances between different electrical components to ensure that equipment can operate safely without posing a fire or other hazard during current overloads, malfunctions, or other abnormal conditions.

The size of electrical clearances is also affected by factors such as voltage, current and type of equipment. When designing, installing and maintaining low voltage small power distribution unites, relevant standards and recommendations must be carefully followed to ensure the safety and reliability of electrical equipment. In addition, regular inspection and maintenance are key steps to ensure safe operation of electrical equipment.
