A buzzing DB box should not be ignored, especially when the sound is new, becoming louder or accompanied by heat or a burning smell. Some homeowners describe the noise as humming, hissing, crackling or vibration coming from a circuit breaker, RCCB or another component inside the distribution board.

A suddenly high electricity bill does not necessarily mean that your TNB meter is faulty. An increase may occur when electricity consumption rises, appliances are used for longer periods or certain appliances are no longer operating efficiently.

Before reaching a conclusion, compare your consumption in kilowatt-hours (kWh), the billing period and your household usage pattern. A systematic check can help distinguish between actual consumption, an appliance problem, internal wiring and an issue that should be referred to TNB.

Flickering house lights can be caused by something as simple as a failing bulb. However, flickering that affects several lights or happens whenever an electrical appliance is used may indicate a problem with a connection, circuit or electricity supply.

A TNB RJO application may be required when a homeowner or property owner needs to relocate a TNB service cable or service wire connected to the meter-panel location.

The relocation normally involves two separate work scopes. An electrical contractor prepares the meter panel and the consumer’s electrical installation, while TNB handles work involving its service cable and electrical equipment.
