The small power distribution unit (ready board) is a kind of electrical equipment used for indoor lighting and power distribution. The requirements of the box are as follows:

The box body should be made of fireproof, flame-retardant and corrosion-resistant materials, which can maintain stable physical properties in long-term use.

The cabinet should have good structural stability and be able to withstand strong vibration and shock. Especially in mobile equipment such as vehicles or ships, the anti-seismic performance of the cabinet is required to be higher.

The inside of the box should have good heat dissipation performance, be able to dissipate the heat generated by electrical equipment in time, and prevent damage to electrical equipment due to overheating.

The box body should have sufficient sealing performance to avoid the entry of external dust, moisture, corrosive gas and other substances, and protect the normal operation of electrical equipment.

The cabinet should have good anti-theft, anti-diving, anti-fog, anti-electromagnetic interference and other characteristics, and can ensure the safety and stability of electrical equipment in complex working environments.

To sum up, the box body of the small power distribution unit (ready board) is required to have high physical properties and environmental adaptability, which can ensure the normal operation and service life of electrical equipment in various complex working environments.
