NETA ETT Level 2 study plan

NETA ETT Level 2 · Give each week a clear focus.

8 weeks · About 7 hours per week

Week 1

Electrical Safety and Safe Work Practices

  • Define the shock-protection approach boundaries (limited, restricted, prohibited) and state the voltage/fault-current conditions that establish each one

  • Distinguish the hazard categories of electric shock, arc flash, and arc blast, and list the physiological effects of each

  • Select PPE for a described task by matching incident-energy level, voltage class, and glove class to the correct equipment

  • Sequence the lockout/tagout steps for a de-energized feeder, including verification of the absence of voltage and application of temporary protective grounds

Your checkpoint

A single-page written job-hazard brief for a described 480 V panel task that names the boundaries, PPE class, LOTO steps, and grounding requirements, scored against a self-made 10-point accuracy checklist

Week 2

Electrical Safety and Safe Work Practices & Electrical Theory, Schematics, and Print Reading

  • Apply Ohm's law and the power equations to compute current, voltage drop, and available fault current in simple series and parallel circuits

  • Convert between KVA, KW, horsepower, and amperes for single-phase and three-phase loads

  • Explain how system grounding, equipment grounding conductors, and bonding paths control touch voltage during a fault

  • Identify the conditions under which energized work is permitted and state the justification documentation required

Your checkpoint

Six worked calculations (three circuit, three load-conversion) plus a written justification memo for one scenario where energized work would versus would not be allowed

Week 3

Electrical Theory, Schematics, and Print Reading

  • Identify standard electrical symbols and device designation letters used on one-line, ladder, and wiring diagrams

  • Trace a control circuit from source through pushbuttons, contacts, and coil to return, and state what each device does when energized

  • Interpret the ratings, interrupting capacity, and coordination information shown on a one-line diagram of a distribution system

  • Compare a nameplate data set against the corresponding schematic entry and flag discrepancies

Your checkpoint

A narrated written trace of one ladder control circuit (start/stop with seal-in and overload) explaining each device state, plus a symbol-identification self-test scoring at least 90 percent

Week 4

Electrical Theory, Schematics, and Print Reading & Test Instruments, Measurement Techniques, and Interpretation of Results

  • Describe three-phase motor connections and identify the winding configurations shown on the nameplate and connection diagram

  • Choose the correct instrument for a stated measurement by matching range, resolution, and CAT safety rating to the circuit

  • Explain how a meter's input impedance and burden voltage distort readings in high-impedance and high-current circuits

  • Convert a schematic's expected values into a test-point list that could be used during commissioning

Your checkpoint

A test-point table for one motor control circuit listing each measurement, expected value, instrument, range, and CAT rating, with a one-paragraph rationale for each instrument choice

Week 5

Test Instruments, Measurement Techniques, and Interpretation of Results

  • Perform and document insulation resistance tests, and apply the minimum acceptable values and temperature correction factors

  • Explain when to use a low-resistance ohmmeter versus a standard DMM and why a four-wire measurement is required for busbar joints

  • Interpret a clamp-meter reading taken on a multi-conductor bundle and identify the conditions that make the reading invalid

  • Distinguish instrument inaccuracy from genuine system faults using repeat measurements, alternative instruments, and known reference loads

  • State the safety precautions for measuring ground resistance with a fall-of-potential tester near energized equipment

Your checkpoint

A written measurement report for three simulated test scenarios (insulation resistance, contact resistance, ground resistance) that states the pass/fail conclusion and the reasoning behind each judgment

Week 6

Inspection and Testing of Electrical Power Equipment and Systems

  • List the inspection items for dry-type and liquid-filled transformers, including dielectric fluid level, gauge readings, and temperature indicators

  • Describe the acceptance and maintenance tests performed on low-voltage circuit breakers and the meaning of contact resistance and trip-time results

  • Identify cable and termination defects detectable by visual inspection, infrared survey, and insulation resistance testing

  • Specify torque verification requirements and the documentation needed for busbar and lug connections

Your checkpoint

A completed inspection checklist template for one equipment type (transformer, breaker, or cable run) covering visual, electrical, and mechanical checks, with pass/fail criteria written for each line item

Week 7

Inspection and Testing of Electrical Power Equipment and Systems & Test Instruments, Measurement Techniques, and Interpretation of Results

  • Interpret protection-device test results and explain how trip-time curves are verified against the coordination study

  • Assess trended insulation resistance and contact resistance data to determine whether a degrading condition exists

  • Explain how battery and DC system tests (capacity, impedance) indicate remaining backup capability

  • Diagnose three described fault scenarios by combining test results from more than one instrument

Your checkpoint

Three short diagnostic write-ups, one per fault scenario, each naming the most probable cause, the confirming test, and the recommended corrective action

Week 8

Electrical Safety and Safe Work Practices & Electrical Theory, Schematics, and Print Reading & Test Instruments, Measurement Techniques, and Interpretation of Results & Inspection and Testing of Electrical Power Equipment and Systems

  • Complete timed practice sets across all four domains and record accuracy by domain

  • Re-teach the two weakest subareas using self-generated summary sheets and re-test them

  • Rehearse the calculation types (power, fault current, ampacity, test-value interpretation) under time pressure

  • Consolidate safety, instrument, and inspection criteria into a single pre-exam reference sheet

Your checkpoint

A scored 100-question timed practice exam with a domain-by-domain accuracy table showing at least 80 percent overall and no domain below 70 percent

Milestones

Week 2: Can state the approach boundaries, select correct PPE for a given voltage and task, and solve Ohm's law and three-phase power problems without notes, scoring at least 85 percent on a 25-question self-quiz covering domains 1 and 2

Week 4: Can trace an unfamiliar ladder diagram device by device and justify each instrument choice by range and CAT rating; test-point table reviewed against the schematic with no missing measurements

Week 6: Can state acceptance criteria for insulation resistance, contact resistance, and torque, and produce a complete inspection checklist with pass/fail limits from memory for one equipment type

Week 8: Timed full-length practice exam completed at 80 percent or higher overall, with every domain at 70 percent or above and a written remediation list for any remaining weak subarea
