In any electrical system, protection is the most important requirement to secure both human lives and appliances from any damage. The THREE PHASE EARTH LEAKAGE DETECTION (TDELD), is a design which could be implemented in three phase electrical environment to provide protection to user as well as equipments against any earth leakage fault. Being a microcontroller based solution, it provides ease and luxury at the user end with the help of its auto reset and display features. This research will attempt to improve the existing ELCB design using PIC microcontroller to automatically switch back system to its normal mode when the TDELD tripped during any electric shock or temporary earth leakage while in permanent leakage fault, it provide input control to bring back the system to its normal operation. The results of this research after doing several tests have shown that the average sensitivity value for TDELD against leakage current is better than what could be found in a conventional ELCB.
