Why Lights Flicker and Dim

May 24, 2025 · Fault Finding

Diagnosing voltage drop, loose neutrals and load issues.

Flickering is often dismissed as a bulb problem when it is actually a warning of a loose connection or overloaded circuit.

Key Points

  • Loose neutral in the board or a junction
  • Voltage drop on long cable runs
  • Incompatible dimmers and LED lamps
  • Large motor loads starting on the same circuit

What This Means for Your Property

Electrical decisions compound. A shortcut taken today becomes an expensive rework, a failed inspection or a declined insurance claim later. The safest route is always the documented one: a written quote, compliant materials, correct testing and a certificate on completion.

If you are unsure how any of this applies to your home, complex or premises in Gauteng, speak to a registered electrician before spending money. A short conversation usually saves far more than it costs.
