PREAMBLE

ELECTRICAL SUPPLY - DOM DOMESTIC ESTIC HOUSE WIRING & ACCESSORIES AND LLIGHTING IGHTING 1. 1.1 1 Introduction Level 1 laboratory activity refers to condition where the problem and ways & means are guided and given to the students. However, the answers to the assignment are left to the students to solve using the group creativity and innovativeness. The activity is to slowly be introduced and inculcate independent learning amongst students and prepare them for a much harder task of openended laboratory activities. In this laboratory activity students will be introduced to the concept, principles and the mechanism of the single phase electricity supply demonstration set. 1.2 Objective The objectives of this open-ended laboratory activity are: 1) To introduce students to the concept, principles and the mechanism of the single phase electricity supply demonstration set in the Building Services Laboratory. 1.3 Learning Outcomes At the end of the laboratory activities, students would be able to: 1) Identify the correct equipments used in a domestic house wiring and accessories and also lighting. 2) Analyse the operation system of a domestic house wiring and present it in typical format of a laboratory report. 3) Work in a group to produce technical report. 1.4 Theoretical Ba Background ckground Source of electricity for small house: Transformer A transformer is a device that transfers electrical energy from one circuit to another through inductively coupled conductors. There are two types of transformers which are step-up transformers and step-down transformers.

LABORATORY MANUAL

Main Switch Board A distribution board (or a Main switch board) is a component of an electricity supply system which divides an electrical power feed into subsidiary circuits, while providing a protective fuse or circuit breaker for each circuit, in a common enclosure. Earth Leakage Circuit Break An Earth Leakage Circuit Breaker (ELCB) is a safety device used in electrical installations with high earth impedance to prevent shock. It detects small stray voltages on the metal enclosures of electrical equipment, and interrupts the circuit if a dangerous voltage is detected.

Residual-Current Circuit Breaker (RCCB) Residual-Current Circuit Breaker (RCCB) is an electrical wiring device that disconnects a circuit when it detects that the electric current is not balanced between the energized conductor and the return neutral conductor.

PROBLEM STATEMEN STATEMENTT

©FKA, UiTM, PAHANG

Student is required to study the electricity supply and wiring of a small house. Knowledge of the wiring system will helps student in the house construction in the future. A single phase electricity supply demonstration set in the Building Services Laboratory is use to study the electricity supply and wiring of a small house. As the demonstration set is not a real electricity wiring system in the house, student is encourage to further study the source of electricity, service intake point, incoming cable, consumer unit, circuit breaker, main switch and out-going cable, trunking, conduit, switch socket outlet and lightings.
