Electrical short-circuit is one of the main causes for the increasing fire accidents in summer, according to the Electrical Inspectorate. It said negligence, improper maintenance, bypassing safety devices, ignoring earthing system and using sub-standard wires and equipment were some factors contributing to these mishaps.
To prevent fire accidents, consumers need to follow various safety measures. House owners have to check phase and neutral connections. The earth wire has to be of same size in single phase circuit.
“Do not bypass fuses, miniature circuit breaker (MCB), earth leakage circuit breaker (ELCB), residual current circuit breaker (RCCB) etc., of all protective devices. The rating of fuses, moulded case circuit breaker (MCCB) and MCB of all protective devices shall not be more than the cable rating,” says Electrical Inspector J. Padma Janardhan Reddy.
According to him, minimum one earth pit for neutral and equipment earthing with suitable earth electrode in each house and commercial building should be provided.
Check the conductivity and connectivity of the earthing system from equipment to the earth electrode.
Electrical works should be carried out through a licenced contractor only. Avoid overloading three-pin sockets by adding multi-plug sockets in the house for electrical appliances.
Avoid connecting electrical appliances without verifying incoming wire current carrying capacity. Check loose connections and replace insulation-burnt cables.
Stop electrical appliances if they make abnormal sound while using them. Use them after rectifying the problem.
