EET 125: Drawing and Installation Methods 2 Project: Commercial Facility 2022 Early submission deadline is before 12:01am Week 11. Projects that meet the early submission deadline will receive a 5% bonus. Project submission deadline is at the beginning of the lecture on Week 11. Late projects will not be accepted and will receive a mark of 0 · Group sizes of 1 to 4 people · In this project, follow the Canadian Electrical Code carefully. Neatness and readability are very important. Freehand drawings will not be accepted. · Make sure you meet all CEC requirements. · Make it Professional (more than just a school project) · Report format: · Title page with perspective company name. · Introduction detailing proposal for your project. · Explanation of group member contributions. · Information as laid out below in Steps 1 through 8 (Majority of marks) · Conclusion. · Bibliography · Diagrams / Drawings listed as appendix. · One file (PDF, PowerPoint, or Word DOC) · For the electrical item in the attached group list, your group will be responsible for detailing all the information needed to install the assigned circuit. (See project list “Appendix A”) Step 1:Determine Disconnect / Fuse / Breakers sizes for the items attached to your circuit. Step 2:Identify your cable route per your determined start and end points. Create a set of diagrams that will show the route and information such as fittings, expansion joints, notes on cable/conductor size and type etc. Step 3: Calculate conductor length. (Lengths to be shown on diagram form Step 2) Step 4:Determine conductor type and sizing (assume Overcurrent devices are unmarked with respect to rule 4-006.1 In addition to using the code book tables for wire size, you will need to complete 1) a “Voltage Loss” calculation (see unit 3 of your Commercial text) 2) a “Distance to center of distribution” calculation. (use Table D3 from Code Book) Assume 3% maximum voltage drop for both cases. Step 5:Determine conduit sizing per code book. Step 6:Create a material list needed for the installation of the electrical equipment. Don’t forget: Include breaker from the panel, any conduit/fittings, conductors/cables, mounting/support devices for cable/conduit (straps, clips, connectors, screws, etc.), end of line device (such as receptacle or pedestal), boxes, etc. You do not need to include prices or structural materials such as asphalt, concrete, backfill, gravel etc. Make it professional: use Excel or other appropriate electronic program, not hand written. Step 7: Complete a symmetrical short circuit current availability calculation to the utilization point for your circuit (SEE UNIT 18 FOR EXAMPLES). · Assume infinite source from utility to 350kVA 120/208V, 3PH, 3% Z pad mounted transformer located at North West corner of site. · Conductor types per the Riser diagram and Step 4 · Assume length of conductors from Pad mounded transformer to switch gear is 25m · Additional conductor lengths will be dependent on panel and utilization point.
