To prevent fire from electrical systems, consumers should check phase and neutral connections. The earth wire has to be of the prescribed size in a 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,” an expert says. 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.
