Troubleshooting power supply failure in distribution box

Check the electrical load and ensure that the sensors do not exceed the 10 Amp maximum. Long cable runs can result in a voltage drop, which can be solved by using a heavy gauge wire. Check the tightness of electrical connections along the power supply. In modern power systems, distribution boxes are the core equipment for power distribution and control, and their stable operation is crucial to ensuring the safety and reliability of power supply. Do not touch live parts, turn off the corresponding power switch to avoid the risk of electric shock. [pdf]
