The ELTEI601 module is designed to equip trainees with the essential skills for performing residential and commercial electrical installations. Students begin by learning to interpret architectural electrical plans and investigate sites to identify specific load requirements. The course includes instruction on estimating costs, forecasting load demand, and selecting correctly sized cables and protective devices. Hands-on training covers the installation of routing systems, cables, and various electrical fixtures according to manufacturer guidelines.Trainees gain practical experience with various switching circuits, including advanced energy-saving controls like sensor-based and time-based switches. Instruction also extends to the selection, installation, and maintenance of engine standby generators for backup power needs. Learners are taught to perform energy audits and install capacitor banks for power factor improvement in commercial buildings. The module concludes with essential post-installation tasks such as testing, commissioning, maintenance, and the preparation of as-built drawings.
