What Are The Risks Of Disassembling A Wall Switch Yourself?

Disassembling Wall Switch by non-professionals will face several serious risks. These hazards involve multiple aspects such as personal safety, electrical system integrity, and home facilities, and require sufficient attention.

Risk of electric shock

Failure to disconnect power according to regulations is the most direct threat. Even if it is believed that the relevant circuit breaker has been turned off, there is still a very high risk if a voltage tester is not used to verify it. Contact with live electrical wires can result in fatal electric shock, the most serious consequence of electrical work.

Fire Hazard

Improper disassembly may damage the insulation layer of the wires, and the exposed wire cores are prone to short circuits during operation. Problems such as aging wiring, series overload of wiring, and mismatch between power supply operating current and socket power can lead to long-term overload and may cause a fire. In damp environments such as bathrooms, the risk of short circuits caused by moisture seepage is even more pronounced.

Wiring error

The wiring positions of the live wire, neutral wire, and ground wire are crucial to system safety. If the neutral wire and the ground wire are reversed, the equipment will experience blackout lights and circuit breaker tripping, or even electrical appliance malfunctions. These types of errors are difficult to detect immediately with the naked eye, and the potential for problems can be long-term.
