ESAA Intermediate Level Exam study guide
ESAA Intermediate Level Exam · Work through your exam, one topic at a time.
The ESAA Intermediate Level Exam is a multiple-choice credential aimed at working electrical and automation technicians who already have foundational field experience and want independent verification of their knowledge. It suits maintenance electricians, controls technicians, and reliability staff who troubleshoot power systems, motors and drives, instrumentation loops, and PLC-controlled processes. The ESAA Intermediate Level Exam study guide has 6 sections and about 3,301 words.
01Electrical Power System Fundamentals
Power System Fundamentals questions check whether you can move between the physical system and its numbers: three-phase relationships, percent impedance, transformer ratings, power factor and fault levels. Expect short calculations rather than derivations, plus qualitative items on transformer connections, grounding and power quality.
394 words, about 2 min02Motors
Motor questions test the relationship between speed, slip, torque, current and thermal limits, plus the practical detail that separates a technician from a textbook: NEMA design letters, service factor, voltage unbalance and connection practice. n s = 120 f ÷ P (P = poles).
447 words, about 2 min03Motor Controls and Variable Frequency Drives
This domain covers the control chain from the disconnect to the shaft: starters and overloads, control-circuit logic, and the VFD as converter–DC link–inverter. Questions mix component selection with drive application math.
424 words, about 2 min04Instrumentation and Process Measurement
Expect loop signal conventions, transmitter selection, sensor physics, calibration concepts and P&ID literacy. Many items are conversion questions - going from a milliamp reading back to an engineering value, including square-root extraction for differential-pressure flow.
404 words, about 2 min05Programmable Logic Controllers and Automation Systems
PLC items test the scan cycle, I/O wiring conventions, analog scaling, program structures and network basics. Expect at least one scaling calculation and several questions on where safety functions must live.
415 words, about 2 min06Electrical Safety
Safety questions cover the two hazards - shock and arc flash - plus the procedures that control them: hazard assessment, boundaries, lockout, verification and PPE selection. Answers are judged against CSA Z462 or NFPA 70E practice, so terminology matters.
