Electricity is basic human needs. Almost of all human activities need an electrical power. The amount of electrical power depends on its human needs. In small house scale, especially in low power house 450VA, electrical load that can be used is limited. MCB trip often happened when the electrical load is overlimit. Electrical power control system need to be applied on this case to avoid trip happens. The purpose of this final project is to make a system that can monitor the electrical current and based on it, this system can control the electrical current use to avoid overlimit use of electrical power. The result is system can do its task to monitor the use of electric current with 10% maximum error percentage and system can control the use of electric current so electric current that used is bellow 2 Ampere.
