Design and Construction of Electrical Power Supply System: The Local Content Addition

Abstract

This paper presents the design and construction of an electrical power supply extension box intending to incorporate local content addition as an alternative to imported boxes. The local content addition is aimed at reducing the importation of off-the-shelf electrical power supply extension boxes and replacing them with locally sourced components. The design process began with a review of the literature on the current uses of extension boxes in the electrical power supply. This was followed by the selection of the various components and the construction of the box. To test the efficacy of the local content addition, a series of tests were conducted to ascertain the box’s performance and general reliability. The results of the tests revealed that the designed extension box was able to outperform the off-the-shelf boxes in terms of safety, durability, and efficiency. The advantages of the local content addition design in comparison to the off-the-shelf boxes were also discussed. This study is expected to open up the use of locally sourced components in the electrical power supply industry and to bring about a reduction in the cost of power supply systems. The paper provides a methodological approach to the design and construction of an Electrical Power Supply Board with the addition of local content.
