Introduction
The CFESA certification examination assesses the technical
competency of commercial food equipment service
technicians across electrical, gas, steam, and refrigeration
systems. It evaluates foundational theory, applied diagnostic
reasoning, regulatory compliance, and safety procedures
required for field service. The multiple-choice and scenario-
based format emphasizes real-world troubleshooting,
decision-making, and adherence to EPA, NFPA, and industry
,standards, preparing technicians for certification and
professional excellence in food equipment repair.
Section One: Questions 1–100
Question 1
What is Ohm's law?
A. V = I / R
B. V = I × R
C. I = V × R
D. R = V × I
🟢 Correct answer B.
🔴 RATIONALE: Voltage equals current multiplied by
resistance. This fundamental relationship is used to calculate
any one value when the other two are known.
Question 2
Which meter measures current without breaking the circuit?
A. Voltmeter
B. Clamp-on ammeter
C. Ohmmeter
D. Megohmmeter
,🟢 Correct answer B.
🔴 RATIONALE: Clamp-on ammeters sense the magnetic
field around a conductor, allowing current measurement
without disconnecting the circuit.
Question 3
How is a voltmeter connected to a circuit?
A. In series
B. In parallel
C. In series-parallel
D. Across a capacitor only
🟢 Correct answer B.
🔴 RATIONALE: Voltmeters measure potential difference
across two points and must be connected in parallel with
the load being tested.
Question 4
Before using an ohmmeter, you must:
A. Energize the circuit
B. De-energize the circuit
C. Short the leads
D. Set to DC volts
, 🟢 Correct answer B.
🔴 RATIONALE: Ohmmeters supply their own voltage;
external power will damage the meter and produce
inaccurate readings.
Question 5
Continuity mode on a multimeter will:
A. Measure voltage
B. Beep if the circuit is complete
C. Measure capacitance
D. Measure temperature
🟢 Correct answer B.
🔴 RATIONALE: Continuity mode checks for closed paths
and provides an audible signal when a complete circuit is
detected.
Question 6
What is the voltage between any two hot lines of a 230-volt
delta power supply?
A. 115V
B. 208V
C. 230V
D. 240V
