ELECTRIC CIRCUIT BREAKER (ELCB)
Elcb is very important in domestic/industrial installation.It is a source of security to any electrical wiring. Incase of any spark or malfunction in the system, it will trip off and disconnect the current or voltage to house or in the industry, thereby preventing fire disaster.
