Abstract
The study identified competencies required for domestic and industrial electrical installations for successful self-employment in the informal sector of the economy of Enugu State. Two specific objectives guided the study. Accordingly, two research questions were posed that were in line with specific objectives, and two hypotheses were tested. The study adopted a descriptive survey research design. The study was conducted in Enugu metropolis. The population for the study was 95, made up of 52 technical teachers and 43 employers in electrical/electronics in Enugu State. There was no sampling as the population is manageable. A structured questionnaire developed by the researchers was used for data collection. The instrument was validated by three experts; two from the Department of Technology and Vocational Education and one from the Measurement and Evaluation in the Department of Computer and Mathematics Education all from the Faculty of Education, Enugu State University of Science and Technology (ESUT), Enugu. A reliability coefficient of 0.81 was obtained using Cronbach's alpha method. A total of 86 copies out of 95 copies of the instrument correctly filled and returned were used for the study, representing 90.5 percent return rate. Mean was used to answer the two research questions. The two null hypotheses were tested at 0.05 level of significance using t-test statistic. The study revealed that domestic and industrial installations competencies required for self-employment in the informal sector of Enugu include; ability to carry out connections in single phase distribution fuse board, ability to install electric motors, earth continuity conductor and electric motors. In addition, the study showed that technical college teachers and employers in electrical/electronic did not differ significantly in their opinions on the domestic electrical installations competencies required of technical college graduates for self-employment in the informal sector of Enugu State. It was recommended among others that competencies needed by the students as identified in the study should form the basis of instruction by technical college teachers.
