Abstract

Distribution board forms an integral part of a domestic electric supply system, whereby its main function is to divide an electric power feed into subsidiary circuits throughout the building whilst providing protection for each circuit via protective fuses. For security reasons, the distribution board is commonly placed at a high ceiling or were put on the high side of a wall. However, this type of placement creates a problem, which is accessibility. To be precise, due to the distribution board be commonly placed at a high place, users often having trouble accessing the distribution board should it become faulty. This is especially true in situations whereby the users are required to replace any faulty fuses, switches, or to reset any tripped switches due to circuit overload. This project aims to address such problem using several simple inventions. By using servo motors which will be put beside each switch inside the distribution box, it will automatically reset any tripped switches, thus eliminating the need for the user to physically reset those tripped switches. In addition, the implementation of sensors inside the distribution box will allow for the users to be notified of any faulty switches or fuses via their mobile phones. This will save the users’ time as they are not required to go through the hassle in identifying which switch or fuse that is faulty inside the distribution box themselves. It is hoped that this project can assist the users with the problem as mentioned using the solution as proposed.
