Development of an Automated Three-Phase Distribution Box System

Nowadays, most electrical appliances require continuous power supply. For domestic
use, crucial appliances such as refrigerator, aquarium and alarm system highly depend
upon the continuity of power supply. However, if they are left without electricity due to
power outage or blackouts caused by internal or external disturbance, the discontinuity
of power supply could be a critical issue to some involving party. Blackouts may be due
to short circuit, fault or the overloading of electricity mains. During power outage,
Residual Current Device (RCD) detects fault currents from live to the neutral wire
within circuit and will trip to prevent shock. This circumstance can increase safety when
a house is left unoccupied. Be that as it may, the power will remain switched off until
manually reset by man. Thus, an Automated Three-phase Distribution Box System is
being developed to overcome tripping problem.
