NICET EPT study plan

NICET EPT · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Cables, Grounding, and Insulation Systems

  • Classify at least eight cable constructions by insulation type, jacket, temperature rating, and permitted application, and record the comparison in a reference table

  • Size feeder and branch-circuit conductors for ampacity with adjustment and correction factors applied across five load scenarios, showing each calculation step

  • Compute equipment grounding conductor and grounding electrode conductor sizes from overcurrent device ratings for ten cases and cite the governing rule for each

  • Sketch a grounding and bonding single-line for a service with one separately derived system, labeling every bonding jumper, electrode, and neutral-to-ground connection

Your checkpoint

A ten-problem conductor and grounding sizing worksheet with worked solutions, cited rules, and a one-page cable/insulation comparison table.

Week 2

Cables, Grounding, and Insulation Systems & Field Testing, Commissioning, and Documentation

  • Explain insulation resistance testing theory well enough to justify test voltage selection and reading interpretation for low-voltage and medium-voltage equipment

  • Perform the arithmetic for temperature correction of insulation resistance readings and define pass/fail thresholds for five equipment classes

  • Sequence a cable fault-location workflow from preliminary insulation test through time-domain reflectometry interpretation, listing the decision point at each step

  • Draft acceptance test forms for cable and grounding systems that name the instrument, connection points, test duration, and acceptance criterion for each test

Your checkpoint

A completed insulation-resistance test report template populated with representative readings for a three-phase feeder, including temperature correction math and a pass/fail determination.

Week 3

Field Testing, Commissioning, and Documentation

  • Write a commissioning plan for a distribution upgrade that lists inspection hold points, energization prerequisites, and witness requirements in execution order

  • Assemble the pre-energization checkout sequence for a switchboard, covering torque verification, phase rotation, insulation tests, and functional trip checks

  • Construct a documentation turnover index that maps each test record to the equipment tag it proves out

  • Differentiate factory, acceptance, and maintenance test intervals and state which records a commissioning package must retain

Your checkpoint

A commissioning test pack for a 480 V switchboard containing the checklist, individual test forms with acceptance criteria, and a tagged turnover index.

Week 4

Electrical Safety, Codes, and Standards & Power System Fundamentals and Circuit Analysis

  • Determine shock approach boundaries and select protective equipment for five energized task scenarios using the applicable tables and justified assumptions

  • Solve twelve series-parallel and three-phase AC circuit problems computing impedance, current, power, and power factor

  • Convert a one-line diagram into a per-unit impedance model and use it to estimate fault current at two downstream points

  • Order the lockout/tagout and energized-work permitting steps for a repair task and identify which step is the point of no return

Your checkpoint

A fifteen-problem circuit-analysis and electrical-safety set, self-scored, with every missed item reworked and annotated with the concept it tested.

Week 5

Power System Fundamentals and Circuit Analysis & Transformers, Switchgear, and Distribution Equipment

  • Interpret transformer nameplate data and compute full-load currents on both sides for four ratings at their actual voltages

  • Compare delta-delta, delta-wye, and wye-wye connections and predict the phase shift and harmonic behavior each produces

  • Use percent impedance and base kVA to estimate available fault current at a transformer secondary and at a downstream panel

  • Distinguish metal-clad from metal-enclosed switchgear and match interrupting, close-and-latch, and bus bracing ratings to stated system conditions

Your checkpoint

A transformer and switchgear data sheet for a 1500 kVA, 13.8 kV to 480Y/277 V unit showing full-load currents, turns ratio, impedance-derived fault current, and required equipment ratings.

Week 6

Transformers, Switchgear, and Distribution Equipment & Rotating Machinery and Motor Controls

  • Compute full-load current, overload protection range, conductor ampacity, and branch short-circuit protection for two motors of different horsepower

  • Read a ladder diagram and write the plain-language operating sequence for start, stop, seal-in, and interlock branches

  • Explain reduced-voltage and variable-frequency starting well enough to select the appropriate method for three stated load and utility constraints

  • List the failure modes a variable-frequency drive injects into a system and the mitigation for each

Your checkpoint

A motor branch-circuit design sheet for one 100 hp and one 25 hp motor, including overload sizing, conductor sizing, protection selection, and a labeled control sequence narrative.

Week 7

Rotating Machinery and Motor Controls & Protective Relaying, Instrumentation, and Control

  • Interpret time-current curves to describe coordination between an upstream feeder relay and a downstream device at two fault levels

  • Propose pickup and time-dial settings for an instantaneous and a time-overcurrent element, stating the constraint each setting satisfies

  • Calculate CT ratio and burden requirements for a metering and a protection circuit, and explain why the two differ

  • Scale a 4-20 mA loop across a stated engineering range and convert three milliamp readings into process values

Your checkpoint

A protection settings worksheet for three relays showing proposed pickup and time-dial values, the coordination logic behind each, and a CT/VT sizing summary.

Week 8

Protective Relaying, Instrumentation, and Control & Electrical Safety, Codes, and Standards & Cables, Grounding, and Insulation Systems & Field Testing, Commissioning, and Documentation

  • Rank all seven domains by demonstrated weakness using scores compiled from prior weeks' deliverables

  • Complete one timed mixed-topic practice set and log every error by root cause rather than by topic name

  • Re-derive from memory the ten formulas and tables most often missed during the eight weeks

  • Build a one-page exam-day reference sheet limited to items that can be reconstructed in under two minutes

Your checkpoint

An error log from a timed mixed-topic practice set with each missed item reworked, plus a ranked final-week review list and a one-page reference sheet.

Milestones

Week 2: Correctly size conductors and grounding conductors in 10 of 10 cases and explain the difference between an insulation resistance pass and a fail without notes.

Week 4: Score at least 80 percent on the fifteen-problem circuit and safety set, and state all shock approach boundary names and their ordering from memory.

Week 6: Complete both motor branch-circuit designs and the transformer data sheet with no unresolved calculation gaps, and narrate a ladder diagram's sequence without referring to the answer key.

Week 8: Improve timed practice-set score by at least 10 percentage points over week 6 baseline, and show that every logged error has a written correction.
