ELEC-09002 Applied Electrical Codes for Single Phase Multiple Dwelling Installations 

This assignment was different from the service entrance calculation tasks. Instead of focusing only on numbers, the goal was to design and present a poster that illustrated electrical connections for both single‑phase and three‑phase multi‑dwelling residential buildings. 

In the ELEC‑09002 poster assignment, my specific responsibility was the grounding and bonding system. I illustrated how grounding conductors connect equipment and panels safely to earth, and how bonding ensures all metallic parts remain at the same potential to reduce shock hazards. I labeled conductor types, sizes, and color codes, and highlighted TTBS/NEC requirements for grounding rods and bonding jumpers. During the presentation, I explained why proper grounding and bonding are critical for safety, fault current dissipation, and overall compliance. 

Group Members’ Contributions:

• Research Lead – gathered TTBS and NEC code references, ensuring our calculations and poster were compliant.

• Diagram Designer – created the floor plan and electrical layout diagrams for single‑phase and three‑phase systems, including service entrances, feeders, and panel boards.

• Code Compliance Checker – reviewed the floor plan for violations such as overloaded circuits, improper spacing, and missing GFCI protection, then documented corrective actions.

• Presenter – led the oral presentation, explaining the overall design and answering questions from the instructor and classmates.

• Documentation Officer – compiled the group’s work into a professional report and digital copy of the poster, making sure all references and legends were included.

The ELEC‑09002 individual assignment asked me to design a complete electrical system for a two‑story townhouse with four apartments. I had to analyze the layout, determine electrical requirements, perform load calculations, plan service entrances and feeders, create schematics, and provide a bill of materials, cost estimate, and design justification — all in compliance with NEC, TTBS, and local codes.
