Introduction
If your lights are flickering frequently, it's time to take a closer look at your electrical wiring.
Flickering lights are not just annoying—they can be dangerous. In Malaysia, many homes experience lighting issues due to aging wiring, poor installation, or an overloaded MCB breaker. This article explains what might be going wrong and how to fix it safely.
Common Causes of Flickering Lights
Loose Bulbs or Fittings – Sometimes the issue is as simple as a loose bulb or a faulty light fixture.
Power Surges – Appliances like air conditioners and refrigerators can cause temporary dips in voltage, resulting in flickers.
Faulty Electrical Connections – Poor electrical wiring can cause intermittent connection issues, leading to flickering or dimming lights.
How Faulty Wiring Contributes to Flickers
Aging or Damaged Wires – Wires wear out over time. Exposed or frayed wires are common culprits in wiring rumah.
Inadequate Load Handling – Outdated parallel circuits might not be able to handle modern electricity demands, causing instability.
DIY Wiring Gone Wrong – Unprofessional electrical setups can lead to inconsistent power delivery and safety hazards.
The Importance of Proper Wire Color Code
Understanding Wire Colors
Red – typically used for live wires
Black – often for neutral wires
Green/Yellow – for grounding
Following the wire color code ensures safe and effective electrical wiring practices. Errors can lead to short circuits or fire hazards.
