NEC Architecture · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Wiring and Protection & Wiring Methods and Materials

  • Map every Article 250 grounding and bonding requirement to a one-page decision flowchart

  • Solve 25 practice problems on overcurrent protection and identify the governing article for each

  • Build a personal index of Chapter 3 wiring method articles by installation type

  • Explain the difference between grounded, grounding, and bonding conductors without notes

Your checkpoint

A two-page grounding/bonding flowchart plus a 25-problem error log with article citations

Week 2

Wiring and Protection & Wiring Methods and Materials

  • Calculate conductor ampacity adjustments for bundling and ambient temperature across 10 scenarios

  • Compare raceway fill requirements for EMT, IMC, and PVC using Chapter 9 tables

  • Trace cable and conductor support and securing rules for three wiring methods

  • Draft a comparison sheet of permitted and prohibited uses for each Chapter 3 method

Your checkpoint

A 10-scenario ampacity worksheet with all table references shown

Week 3

Tables and Annexes & Wiring and Protection

  • Navigate Annex C and Chapter 9 tables to size conduit for 8 conductor combinations

  • Convert between Chapter 9 table values and Article 310 ampacity tables in 10 exercises

  • Summarize how to use Tables 310.16 and 310.15 adjustment factors together

  • Identify which annexes are informational versus enforceable

Your checkpoint

A completed conduit-sizing and ampacity table exercise set with answers verified against the code text

Week 4

Equipment for General Use & Special Conditions

  • Outline switchboard, panelboard, and motor disconnect requirements in a single reference sheet

  • Differentiate general-purpose versus special-condition installation rules for 5 equipment types

  • Solve 20 mixed equipment problems under timed conditions

  • List the marking and labeling requirements most often missed on equipment

Your checkpoint

A timed 20-question equipment quiz scored at 80 percent or higher

Week 5

Special Occupancies & Special Equipment

  • Compare classified-location division and zone concepts without conflating them

  • Summarize health care facility and assembly occupancy wiring rules into a checklist

  • Distinguish special equipment articles by scope and applicability

  • Solve 15 scenario problems requiring selection of the correct special article

Your checkpoint

A two-column special occupancies versus special equipment comparison matrix

Week 6

General Requirements and Administration & Plan Review and Code Application

  • Sequence a plan review from drawings through inspection using Articles 90 and 100 definitions

  • Apply Article 100 definitions to resolve 15 ambiguous scope questions

  • Draft a 10-item plan review checklist covering load, method, and protection

  • Practice writing code citations in correct article.section format

Communications Systems & Tables and Annexes

  • Outline Article 800 through 840 scope boundaries and cable substitution rules

  • Locate 10 specific values in the tables and annexes within a two-minute limit each

  • Reconcile communications bonding requirements with Article 250 concepts

  • Build a table-navigation speed drill log

Your checkpoint

A table-navigation drill log showing 10 of 10 lookups completed within the time limit

Week 8

General Requirements and Administration & Wiring and Protection & Wiring Methods and Materials & Equipment for General Use & Special Occupancies & Special Equipment & Special Conditions & Communications Systems & Tables and Annexes & Plan Review and Code Application

  • Complete two full-length timed practice exams and record per-domain scores

  • Re-study the two lowest-scoring domains using targeted article review

  • Re-solve every missed question and write the governing citation

  • Confirm readiness by scoring 75 percent or higher overall

Your checkpoint

A scored two-exam results summary with a remediation list for any domain below 70 percent
