The noise level of rural lighting electrical ready boards is high, which may be caused by the following three details and should be taken seriously:

1、 Overload or malfunction of electrical equipment

When the electrical equipment in the rural lighting electrical ready board exceeds the safe current carrying capacity or has faults, it can cause excessive current and cause buzzing or sizzling sounds. This kind of noise not only affects daily life, but may also cause safety accidents such as fires due to equipment overheating. For example, if the live and neutral wires on the load side of the circuit breaker are short circuited, all lighting fixtures will dim after power transmission, and the branch circuit breaker will make noise and shake, posing a great safety hazard.

2、 Loose or aged electrical ready board

Loose electrical equipment or wiring inside the electrical ready board can cause poor contact and produce buzzing sounds. Meanwhile, prolonged use of the electrical ready board and aging of internal electrical equipment may also cause noise. This looseness and aging not only affect the normal operation of the equipment, but may also cause high temperatures due to poor contact, leading to fires. Therefore, it is necessary to regularly check whether the internal connections of the electrical ready board are tight and replace aging equipment in a timely manner.

3、 Environmental interference

The surrounding environment of the electrical ready board (such as high temperature, high humidity, and electromagnetic interference) may also lead to increased noise. For example, in humid weather, the electrical ready board may emit a brief slight sizzling sound, which is a corona phenomenon caused by the ionization of water molecules in the air. However, if the sound persists and is obvious, it may indicate poor contact or short circuit of the circuit. In addition, electromagnetic interference may also affect the normal operation of equipment inside the electrical ready board and generate noise.
