Cause of end board trip
There can be several possibilities for the cause of a switchboard trip. Here are some common causes:
Overload: When the load in the circuit exceeds the rated load capacity of the circuit, the end board may trip to prevent the circuit from overheating or being damaged.
Short Circuit: When a direct short circuit occurs between the phase wires in a circuit or between a phase wire and ground, the end board trips to prevent damage or fire risk from excessive current flow.
Ground Leakage: If there is an electrical leakage problem in the circuit, current can be lost through the ground line, causing the end board to trip when it detects a current imbalance.
Faulty Equipment: An electrical piece of equipment may have malfunctioned, such as damaged motor insulation or a faulty circuit board, causing the end board to trip to avoid further damage.
External disturbances: External factors such as lightning strikes, grid failures, or power supply problems can cause end boards to trip to protect circuits and equipment.
If you are experiencing frequent tripping issues, it is best to have it checked and troubleshooted by a professional electrician. They can use testing and diagnostics to determine the specific cause and take appropriate action to fix the problem.
