The Design and Installation of Electrical Systems in the Building to Self-employed

Abstract

This research study aims to developeand the efficiency of courses and training about the design and installation of electrical system inside the building for self-employed. There were 8 courses in this study including the first unit was the Fundamentals of Electrical Work . The second unit was the Electrical Wire and Wiring. The third unit was the Lamp and Lamp Connection. The fourth unit was the Protective Equipment. The fifth unit was the Tubular in Electrical Work. The sixth unit was the Grounding System. The seventh unit was the Electrical Wiring and Circuit. The eighth unit was the Electrical Installation System Design and Indoor Electrical Installation. The sample groups were the persons who interested in the installation of electrical system and electrical equipments inside the building in Kamphaeng Phet and Tak provinces. They were 25 persons. They got the training 3 days with 24 hours totally. The results of training found that the Fundamentals of Electrical Work had the average point of the test at 8.40 points. The Electrical Wire and Wiring had the average point test at 8.30 points. The average point test of the Lamp and Lamp Connection was 8.30 points. The average point test of the Protective Equipment was 7.90 points. The average point test of the Tubular in Electrical Work was 8.60 points. The average point test of the Grounding System was 8.30 points. The average point test of the Electrical Wiring and Circuit was 8.00 points. The average point test of the Electrical Installation System Design and Indoor Electrical Installation was 8.30 points. The average point test from 8 unites was 8.23 points. The average point of skills’ test was 8.30 points. The efficiency value (E1) was 83.00. The The average point test after the training was 67.40. The efficiency value (E2) was 84.30 which it was higher than the estimation that it fixed at 80/80. The opinion evaluation of the trainees had the average = 4.45 which it was at the good level and it was not different with the criteria U๐ = 4 significantly. From the result of efficiency value in these courses and the opinion evaluation of the trainees, it showed that theses courses had developed efficiently. The trainees gained more knowledge and skills for working increasingly
