1. When the circuit breaker is accidentally tripped, first check whether it is a personnel misoperation. There are two cases of personnel misoperation: one is the operation error; the other is the misoperation caused by improper protection measures on the relay protection circuit. 2. If it is not a mistake, check the operating mechanism for malfunction. For example, whether the circuit breaker tripping mechanism is faulty or whether the circuit breaker automatically trips due to external vibration. 3. If the operating mechanism is checked, it may be caused by two-point grounding in the operating circuit, causing the circuit breaker to automatically trip, or the operating circuit is short-circuited, or some components in the operating circuit, such as anti-skip relays, may cause poor performance. False trip. If the insulation state of the inspection circuit is good, the relay protection device should be inspected to check whether the protection device malfunctions and the circuit breaker automatically trips. In order to ensure the power supply to the user, after the line circuit breaker is automatically tripped, the manual or automatic reclosing device can be used for closing. Over time, battery cables have to be replaced due to corrosion or damage. A bad battery cable can cause intermittent starting issues or lack of power to the vehicle, including arcing or power drains.A battery cable consists of multiple stands of wire encased in synthetic material with different types of battery terminals on each end for a reliable connection. Corrosion is the number one cause of battery cable failure, stopping the flow of electricity.

The main reasons for the accidental tripping of the circuit breaker are: personnel misoperation, self-tripping of the operating mechanism, and electrical secondary circuit problems.
