ABSTRACT
The basic aim of the design and construction of this three phase automatic phase selector is to demonstrate how contactors can be used to switch in between three lines or phases e.g รขโฌล“RED, YELLOW AND THE BLUE PHASEรขโฌÂ without interfering with the contacts.
This type of phase selector is able to switch between phases with the aid of inter-locking one phase to the other either one phase circuit is dependent on the other phase circuit which means that two phase circuit which that two phases cannot come on at the same time.
This research work is divided into six chapters, chapter one emphasizes on the introduction of the topic, the second chapter centers on the review p=of related literature as it regard to the design and construction of this Automatic three phase selector.
