520	1		_aPower system protection plays important role for the safety of humans and electrical equipments in houses or buildings. Besides it also becomes a precondition of the system for obtaining capability and continuous power supply. Earth leakage circuit breaker (ELCB) is an important protection device especially for houses and buildings. The ELCB’s spring trap will trip to isolate the fault from the system when line to ground fault occurs. So the good condition of the ELCB is very important to run the duty as a power system protector. This project is designed to test the earth leakage circuit breaker (ELCB) automatically every month by detecting current through it when it is in off condition. Microcontroller will be use in this project to make the ELCB automatically tested with programmed it for month. During test period, a current detector which is connected series with the ELCB will detect any current that flow through it. When the detector detect currents, mean that the ELCB does not function properly and LED or buzzer will be ON as an indicator for occupant, so that ELCB can be change immediately. The ELCB is in good condition and can function properly when no current detected and DC motor will be used to switch ON the ELCB’s spring trap. Actually this project can improve the ELCB application and also will enhance the safety for occupant of houses and buildings. -Author
