Building Electrification — BTEUP Electrical 6th Semester Syllabus 2026-27

Building Electrification — What This Subject Is About

Building Electrification is the subject that turns a building's drawings into a working electrical system — the wiring, the cables, the protective devices and the earthing that make a home or a commercial complex safe to live and work in. It teaches you to design electrical installation systems in building complexes, and it is the first subject of the final semester. It is a practicum subject (L 2 – P 4) with 11 practicals.

The five units follow the order of a real job: wiring tools and accessories, electrical wires and underground cables, wiring methods and layout, residential building electrification — the heaviest unit at 23% — and protective devices and earthing for electrical installation. One honest note: the unit headings give 04/06/06/08/04 periods (total 28), but the Suggested Distribution of Marks table in the official PDF gives 11/11/11/13/10 (total 56); this page uses the unit-heading figures, since the marks-table figures look copied from a theory subject.

Subject 6.1 (Practicum) • Total 100 Marks • 4 Credits • L 2 – P 4 • 6thth Semester — Electrical Engineering • Session 2026–27
