Electrical (E) Plan Set — Comprehensive Essay Test

Complete all answers and submit to education@sfjohnsonconsulting.com.

Student Name: 1. Describe how to read power plans vs. lighting plans and what each conveys to the field. 2. Explain panel schedules and load calculations and how they inform feeder/conductor sizing. 3. Discuss one-line/riser diagrams and how they coordinate with site power and gear. 4. Summarize circuiting, homeruns, and device tagging for takeoff and installation. 5. Describe lighting fixture schedules, controls, and how to catch spec substitutions. 6. Explain grounding/bonding requirements and where they appear in the E-set. 7. Identify coordination needs with Mechanical and Architectural for equipment power and clearances. 8. Evaluate emergency/standby systems, transfer switches, and code drivers. 9. Outline an electrical takeoff workflow (devices, branch, feeders, gear, lighting, controls). 10. Discuss common RFIs and plan review items in the E-set and how to document them. Responses will be sent to education@sfjohnsonconsulting.com for grading.

1. Power shows devices/circuits/feeders; lighting shows fixtures, controls, switching.

2. Panel kVA, demand factors, AIC; drives feeder/wire/conduit sizing.

3. One-line defines gear sequence, voltages, fault duty, grounding.

4. Circuit tags, homerun arrows, device counts → labor/material takeoff.

5. Fixture types, lumens, controls; verify equals, voltage, mounting.

6. GEC, bonding jumpers, electrodes—shown on one-line/details/spec.

7. MCA/MOP for HVAC, clearances, locations; architectural constraints.

8. Life-safety circuits, ATS types, selective coordination.

9. Count devices/lighting; measure branch/feeder; include supports.

10. Fault current, coordination curves, unclear circuits, gear spaces.
