Electrical Service Design
EEE 4418 lab project on residential electrical service design including floor-wise layout plans, SDB/ESDB/MDB connection diagrams, and load calculations.
Project Overview
This project report presents the complete electrical service design workflow for a residential building as part of the EEE 4418 Electrical Service Design Lab. The work covers planning, protection-oriented distribution design, and practical load estimation for household spaces.
Scope of Work
- Ground floor plan with fittings, fixtures, conduit layout, and legends
- Floor 2-3 plan for electrical point distribution
- Roof plan with air terminals
- Single-line style connectivity for SDB, ESDB, and MDB
- Room-wise lighting and fan requirement calculations
Design Components
- Floor Layout Planning: Electrical points are placed based on room usage and accessibility
- Conduit Routing: Path planning for safe and maintainable cable installation
- Distribution Hierarchy: MDB to ESDB to SDB design for structured power distribution
- Fixture Mapping: Light and fan points are selected using area-based requirements
Calculation Approach
The report applies area-based estimation to determine the number of fixtures:
- Lighting: Estimated from room area using standard illumination assumptions
- Fans: Estimated from floor area using a fixed factor
Sample rooms analyzed include:
- Dining room
- Bedroom A
- Bedroom B
- Drawing room
- Veranda
Learning Outcomes
- Practical understanding of residential electrical service planning
- Skills in preparing floor-wise electrical layouts and legends
- Experience in distribution board interconnection design (MDB/ESDB/SDB)
- Hands-on application of lighting and fan load calculations
- Team-based technical reporting and documentation
