Discoms warn of fire risks caused by faulty wiring, excessive use of ACs

Delhi's power companies warn of fire risks from overloaded circuits and faulty appliances as summer heat rises. Residents urged to ensure electrical safety.

Power distribution companies in Delhi have issued a detailed advisory on Tuesday, warning residents about the risk of electrical fires caused by overloaded circuits, faulty wiring, and poorly maintained appliances, particulary air conditioners (ACs). The warning comes amid the rising temperatures in Delhi during summer.

According to discom officials most fire incidents during peak summer months happen due to internal electrical faults, excessive load and inadequate safety measures.

According to discom officials most fire incidents during peak summer months happen due to internal electrical faults, excessive load and inadequate safety measures. The advisory released by multiple discoms stated that rising temperatures and continuous use of high-power appliances, add stress on household electrical systems, leading to overheating and short circuits.

“During summer, electricity consumption increases due to air conditioners, coolers and other appliances. Many households continue to use outdated or poorly maintained wiring systems, which significantly raises the risk of overheating and fire incidents,” a discom official said.

The advisory stated that air conditioners become the primary cause of electrical fires if they are not regularly serviced or connected to circuits with inadequate load capacity. Officials said that old or repaired AC units often have overheating compressors, damaged insulation and blockages in airflow, increasing the risk of fire hazards.

“Consumers should ensure that their ACs are serviced periodically and connected to proper sized electrical circuits. Old air conditioners consume more electricity and may develop faults,” the official added.

The discoms warned residents against overloading sockets, using damaged cords, charging e-vehicles through domestic wiring. According to the advisory, such practices can obstruct emergency access and intensify fire risks.

“Simple preventive measures can reduce the chances of electrical fires. Consumers should treat electrical safety as a priority,” the official said.

Residents have been advised to install earth leakage circuit breakers (ELCBs) or residual current circuit breakers (RCCBs), conduct annual inspections of house wiring, use ISI-marked electrical equipment and ensure proper earthing connections. The advisory further recommended switching off appliances when not in use.

The advisory also flagged safety concerns arising from unauthorised construction near high-tension lines and illegal cable installations on electricity poles, stating that such practices increase fire hazards and hinder maintenance work.
