How to eliminate the problem of circuit overload after the circuit breaker inside the small power distribution unit trips?

When the circuit breaker inside the small power distribution unit trips, it may be due to an overloaded circuit. To troubleshoot a circuit overload, the following steps can be taken:

Disconnect the load: First, turn off or unplug all load devices (such as electrical appliances, lamps, etc.) connected to the circuit to prevent overload current from continuing to flow through the circuit.

Reset the circuit breaker: Locate a tripped circuit breaker, turn it off completely, and then back on again. This resets the circuit breaker and gives the circuit a chance to re-energize.

Analyze the load: Reconnect the load devices one by one, making sure that the power of each device matches the capacity of the circuit. If a piece of equipment is connected and causes the circuit breaker to trip again, it is likely that the equipment has too much power and you need to consider replacing it with a lower power equipment or connecting it separately from other equipment.

Consider divided power supply: If the circuit load is too heavy, you can consider dividing the load equipment into different circuits for power supply to balance the load and avoid overload.

Consult a professional: If the above steps cannot solve the problem, or there are other electrical faults, it is recommended to consult a professional electrician or electrical engineer, who can carry out detailed inspection and troubleshooting.

Note that care and safety are required when dealing with circuit overloading. Seek professional help if you are unsure how to do this or if there is a safety hazard.
