There are several methods to deal with cable overload issues, including:

Load reduction: Immediately reduce the load on the cable to ensure that the current does not exceed its rated capacity.

Check the connection: Check the joints and terminals to ensure there is no looseness or corrosion, and reduce impedance.

Cooling measures: Improve ventilation or install heat dissipation devices to reduce cable temperature.

Replace cable: If frequently overloaded, consider replacing with a higher capacity cable.

Install protective equipment: Add overload protectors or circuit breakers to prevent cables from continuing to overload.
