What Causes Lights to Flicker
Our Bellville electrical team diagnose and fix flickering lights in residential and commercial properties in Bellville regularly. Flickering lights are caused by loose connections at switches or light fittings, poor connections at the DB board creating intermittent contact, overloaded circuits dropping voltage when appliances start, faulty light switches or dimmer switches, problems with the neutral connection, voltage fluctuations from the municipal supply, or in LED bulbs, incompatibility with dimmer switches. The pattern of flickering often indicates the cause.
When Flickering Indicates Danger
Occasional flickering is annoying, but constant flickering or flickering accompanied by burning smells, hot switches, buzzing sounds from switches, or lights that dim significantly when appliances start indicates a serious electrical fault. Loose connections can cause arcing, which creates heat and fire risk. This requires immediate professional attention.
Our Diagnostic Testing
We test voltage at various points in your electrical system, check all connections at light fittings and switches, inspect the DB board for loose connections, measure voltage drop when appliances are running, test the neutral connection integrity, verify circuit capacity is adequate, and use thermal imaging to detect hot connections. We find the root cause, not just the symptom.
Permanent Flickering Solutions
We tighten or replace all loose connections, replace faulty switches and dimmers, upgrade circuits if they are overloaded, repair neutral connection problems, install voltage stabilizers if municipal supply is unstable, replace incompatible LED bulbs or dimmers, and rewire sections if wiring is deteriorated. We ensure all lights operate steadily and safely. Load shedding can also stress electrical systems and contribute to flickering.
