Check whether the small power distribution unit is qualified. Don’t ignore these areas.

When checking whether the small power distribution unit is qualified, there are several key points that need to be paid attention to to ensure the safety and functionality of the small power distribution unit. These places include:

Installation quality: Check whether the installation of the small power distribution unit is firm and whether it fits tightly with the wall or bracket. Make sure all mounting bolts are in place.

Electrical connections: Make sure that all electrical connections are tight and firm, without loose or loose connections, especially the main power supply and branch circuit connection points.

Grounding: Make sure the small power distribution unit is properly grounded and make sure the ground wire is well connected to avoid dangerous voltage fluctuations in the power system.

Insulation performance: Check the insulation condition inside and outside the small power distribution unit to make sure there are no exposed wires or damaged insulation.

Protection device: Ensure that the circuit breakers, fuses and other protection devices in the small power distribution unit are in normal working condition and can cut off the power supply in time to prevent overload and short circuit.

Protection level: Check the casing and door of the small power distribution unit to ensure that its protection level meets the standards to prevent foreign matter or moisture from entering.

Labels and markings: Make sure labels and markings inside and outside the small power distribution unit are clear and complete to facilitate identification of circuits and components.

Ventilation and heat dissipation: Make sure the small power distribution unit has adequate ventilation and heat dissipation design to avoid overheating of electrical components.

These places are important aspects to ensure the safe and reliable operation of the small power distribution unit and cannot be ignored.
