Course Overview
The Intermediate Electrical Training course at NewTech builds on foundational knowledge to deepen your understanding of electrical systems, advanced circuit design, and regulatory compliance. Aimed at learners who have completed basic training or are already working in the trade, the programme blends theory with intensive practical labs so you can confidently install, test, and commission domestic and small-commercial installations. Emphasis is placed on safe isolation procedures, cable selection, protective devices, and the latest 18th Edition wiring regulations. By the end of the course you will be ready to tackle more complex projects, supervise basic installs, and progress toward professional accreditation.
