GER Licensed Electrical Inspector study plan

GER Licensed Electrical Inspector · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Wiring Methods and Materials & Branch Circuits, Feeders, and Service Calculations

  • Build a one-page table of the Chapter 3 wiring-method articles that matter most for inspection (NM, AC/MC, EMT, IMC, RMC, PVC, LFMC, wireways, cable trays) with the permitted and prohibited uses for each

  • Work through at least 15 ampacity and adjustment problems using the 310.16 table, including ambient-temperature correction and more than three current-carrying conductors in a raceway

  • Derive the standard branch-circuit and feeder load calculation steps (general lighting, small appliance, laundry, receptacle outlet, appliance, and motor loads) and solve 10 practice feeders end to end

  • Sketch a dwelling service calculation from the utility point to the panelboard, labeling each demand factor you applied and why

Your checkpoint

A 20-problem calculation worksheet with worked solutions and cited Code sections, scored at 80% or better

Week 2

Branch Circuits, Feeders, and Service Calculations & Grounding, Bonding, and Overcurrent Protection

  • Compute service and feeder sizing for one- and two-family dwellings, multifamily units, and a small commercial occupancy using the optional and standard methods, and compare the results

  • Select overcurrent devices for motors, air-conditioning equipment, and transformers, applying the 125% and next-size-up rules correctly

  • Trace the grounding-electrode system, equipment grounding conductor, and main bonding jumper paths on a sample service and explain each required connection

  • Distinguish grounding from bonding in at least 10 scenario questions and justify each answer with a Code reference

Your checkpoint

A completed service calculation package for three occupancies (dwelling, multifamily, small commercial) with a one-paragraph justification of each overcurrent and grounding decision

Week 3

Electrical Theory and Fundamentals & Grounding, Bonding, and Overcurrent Protection

  • Solve 20 circuit problems covering Ohm's law, series-parallel networks, power, voltage drop, and conductor resistance, showing every step

  • Calculate voltage drop for branch circuits and feeders at 3% and 5% targets and state when upsizing is warranted

  • Explain the operating characteristics of fuses, molded-case breakers, and ground-fault protection and match each to its application

  • Identify the electrical-theory errors behind 10 common field mistakes (undersized neutrals, shared neutrals, improper paralleling, and similar)

Your checkpoint

A theory-and-protection problem set of 30 items with worked solutions and a list of the Code rules each problem tests

Week 4

Electrical Inspection Procedures and Documentation & Code Enforcement and Plan Review

  • Draft a complete inspection checklist for a residential rough-in and a commercial tenant fit-out, sequenced to the construction schedule

  • Write model correction notices for 10 defects that state the observed condition, the Code section, and the required corrective action

  • Perform a plan review of a sample set of drawings and log every deficiency with a Code citation

  • Describe the permit, inspection-request, and certificate-of-occupancy workflow and the records an inspector must retain

Your checkpoint

A mock inspection report for one project containing at least 10 findings, each with a Code citation and a corrective-action statement

Week 5

Special Occupancies, Equipment, and Hazardous Locations & Wiring Methods and Materials

  • Classify 15 hazardous-location scenarios by class, division or zone, and group, and select the permitted wiring method and equipment for each

  • Outline the inspection points for health-care facilities, assembly occupancies, and motor fuel dispensing sites

  • Verify the requirements for wet, damp, and corrosive locations and for swimming pools, spas, and similar installations

  • List the markings and listings an inspector must confirm on fittings, boxes, and enclosures before accepting an installation

Your checkpoint

A hazardous-location classification and wiring-method decision matrix covering at least 12 scenarios with cited Code sections

Week 6

Code Enforcement and Plan Review & Electrical Inspection Procedures and Documentation

  • Apply the rules for approved materials, listing, labeling, and field evaluation when reviewing submittals

  • Practice resolving conflicts between Code requirements, manufacturer instructions, and local amendments, and document the resolution

  • Write a plan-review comment set for a commercial service and feeder design that cites the specific article and section for each comment

  • Explain the inspector's authority, the appeals process, and the limits of discretion in enforcement

Your checkpoint

A plan-review comment log of 15 items on a sample commercial submittal, each tied to a Code section and marked accept, revise, or reject

Week 7

Safety, Liability, and Professional Ethics & Electrical Inspection Procedures and Documentation

  • Analyze 10 ethical scenarios covering conflicts of interest, gifts from contractors, confidentiality, and reporting unsafe conditions, and state the correct action and rationale

  • Describe the liability exposure of an inspector for negligent inspection and the practices that limit it (documentation, scope statements, consistency)

  • Build a personal safety plan for site inspections covering energized-work avoidance, PPE selection, and lockout/tagout awareness

  • Practice writing defensible inspection narratives that separate observed facts from conclusions

Your checkpoint

A written ethics-and-liability response set of 10 scenarios plus a one-page personal site-safety plan

Week 8

Electrical Theory and Fundamentals & Wiring Methods and Materials & Branch Circuits, Feeders, and Service Calculations & Grounding, Bonding, and Overcurrent Protection & Electrical Inspection Procedures and Documentation & Code Enforcement and Plan Review & Special Occupancies, Equipment, and Hazardous Locations & Safety, Liability, and Professional Ethics

  • Take two full-length timed practice exams under test conditions and score them by domain

  • Review every missed item, identify the underlying rule, and re-read the governing Code section for each

  • Re-drill the two weakest domains until practice accuracy reaches 85%

  • Assemble a one-page quick-reference sheet of the tables and formulas you most often miss

Your checkpoint

Two scored practice exams with a written error analysis and a final quick-reference sheet

Milestones

Week 2: Score at least 75% on a 25-question mixed set drawn from wiring methods, calculations, and grounding, and complete all three service calculations without reference to a worked example

Week 4: Produce the mock inspection report with all 10 findings correctly cited, and pass a 20-question inspection-procedures and plan-review quiz at 80%

Week 6: Complete the hazardous-location matrix and the plan-review comment log, and score at least 80% on a 30-question set covering domains 5, 6, and 7

Week 8: Score at least 80% overall on both timed practice exams with no domain below 70%, and finish the error analysis and quick-reference sheet
