Week 2

  • Perform motor branch-circuit and feeder calculations per Article 430, including 430.52 overload and short-circuit protection and 430.24 feeder sizing

  • Size transformers and apply Article 450 overcurrent protection plus 240.21 tap rules to three tap scenarios

  • Compute voltage drop for feeders and branch circuits and state when it becomes a design rather than code issue

  • Analyze three-phase versus single-phase load balancing and neutral loading for nonlinear loads

  • Work twenty mixed theory problems (Ohm's law, power, power factor, impedance) under a 25-minute timer

Your checkpoint

A worked problem set of 20 motor, transformer, tap-rule, and voltage-drop calculations with an accuracy log noting every miss and its root cause

Week 4

National Electrical Code and applicable New Jersey electrical regulations (official content outline not published in source) & Electrical contracting practice and theory (official content outline not published in source)

  • Locate and summarize the New Jersey administrative provisions that adopt and amend the NEC, including the edition in force and the Uniform Construction Code relationship

  • Outline the permit, inspection, and certificate-of-occupancy sequence for a residential service upgrade and a commercial tenant fit-out

  • Identify which work requires plan review and which licensed trade holds jurisdiction at each step

  • List the NEC Articles most frequently cited on failed inspections and the specific violation each represents

  • Draft a one-page inspection-readiness checklist a crew could use on site

Your checkpoint

A New Jersey permit-to-inspection flow diagram for two project types, with the adopting regulation and NEC edition cited at each node

Week 5

National Electrical Code and applicable New Jersey electrical regulations (official content outline not published in source)

  • Build a lookup drill for Chapter 2 and Chapter 4 Articles (210, 215, 220, 225, 230, 240, 250, 280, 285, 404, 406, 408, 410, 422, 424, 430, 440, 450) and complete 40 timed index-lookup questions

  • Distinguish special-location Articles in Chapter 5 (500-517, 525, 547, 550-552, 555, 590) by occupancy and the extra rules each imposes

  • Apply Chapter 6 and 7 requirements for equipment and special conditions (625 EV charging, 690 solar, 700-702 emergency systems, 705 interconnected sources)

  • Practice reading exceptions, fine print notes, and informational notes correctly, since only the first two are enforceable

  • Write a personal list of the 15 code sections you most often misremember and a memory hook for each

Your checkpoint

A timed 40-question lookup log with per-question find time, target under 90 seconds, and a ranked list of your slowest Articles

Week 6

New Jersey Electrical Contractors Licensing Act of 1962 and Board rules (official content outline not published in source) & Electrical contracting practice and theory (official content outline not published in source)

  • Summarize the New Jersey Electrical Contractors Licensing Act of 1962: who must be licensed, the license classifications, and the qualifying-licensee concept
