During the construction and installation process, the methods to solve and prevent the failure of the distribution box include:

Quality inspection: Make sure the distribution box and its components meet the standards, check whether the wiring is firm, and whether the materials are qualified.

Qualified Builders: Hire an experienced electrician for installation and connections to avoid mistakes and omissions.

Insulation: Make sure the wires are well insulated to avoid short circuits and leakage.

Overload protection: Install an overload protector to prevent equipment damage and fire caused by current overload.

Ventilation and heat dissipation: Make sure the distribution box is well ventilated to avoid failure caused by overheating.

Regular maintenance: Carry out regular inspection and maintenance to discover and solve potential problems in time to ensure safe operation.

Waterproof and moistureproof: If it is installed in a humid environment, take waterproof and moistureproof measures to prevent damage.

Safety signs: Set clear electrical safety signs, indicating switches, fuses, etc., to reduce misuse.

To sum up, qualified construction and maintenance operations, in conjunction with standards and safety measures, can effectively prevent and solve distribution box failures.
