The installation of small power distribution units needs to follow a series of safety regulations to ensure the normal operation of the electrical system and the safety of users. Here are some suggestions:

Location selection: When installing the small power distribution unit, choose a well-ventilated, dry and easy-to-maintain location, away from flammable substances.

Installation height: When installing, make sure the small power distribution unit is at a moderate height to facilitate reading and maintenance, usually between 1.5 meters and 1.8 meters.

Waterproof and dustproof: The small power distribution unit should be waterproof and dustproof to protect the electrical components from moisture and dust.

Cable routing: Cable routing should be neat and orderly and away from objects that may cause damage or short circuits.

Ground protection: Make sure the small power distribution unit and related electrical equipment are properly grounded to prevent electric shock and protect the equipment.

Professional Installation: Installation of the small power distribution unit should be performed by a qualified, experienced electrician and in compliance with local electrical codes and regulations.

Ventilation and heat dissipation: The small power distribution unit should have good heat dissipation capabilities to avoid equipment damage caused by overheating.

Regular inspection: Regularly check the small power distribution unit to make sure there are no damaged or loose wires. If there are any problems, they should be repaired immediately.

Please note that the above advice is general in nature and specific installation steps and regulations may vary by region, so before installing a small power distribution unit it is best to consult a professional electrician or local power department to ensure compliance with local electrical safety standards.
