- FEAD is this site's shorthand for Fundamentals of Electricity - AC/DC, a Level 1 credential from Festo Didactic's industry certification program.
- The credential is delivered through the NC3 partnership using NC3Certs at participating institutions, not through open public testing.
- Domains 1-18 mirror the DC topic list; domains 19-36 mirror the AC topic list.
- Students need at least 70% on each certification examination plus completed hands-on labs; recertification is not required for students.
The Short Answer: Fundamentals of Electricity - AC/DC
On this site, FEAD stands for Fundamentals of Electricity - AC/DC. It is a Level 1 technical-education credential covering the basics of both direct current (DC) and alternating current (AC) circuits, components, measurement, and troubleshooting. The letters come from the name itself: Fundamentals of Electricity - AC/DC.
That is the entire expansion. Nothing else is hiding behind the acronym here. If you arrived looking for a different credential that happens to share four letters, you are in the wrong place, and the rest of this article is about the electricity credential only. For companion explainers on the same subject, see our pages on what FEAD is, FEAD meaning, and what FEAD means.
Who Stands Behind the Name
The credential is issued by Festo Didactic through the Festo Industry Certification Program (FICP), in partnership with the National Coalition of Certification Centers (NC3). Examinations are delivered through NC3Certs at participating institutions. That delivery model matters, because it shapes who can sit for the exam and how. We cover the practical consequences in FEAD requirements.
NC3's September 2026 Festo certification portfolio file lists the combined Level 1 Fundamentals of Electricity - AC/DC scope, and Festo's current program page presents Fundamentals of Electricity as DC and AC preparation with a component sheet for each. In other words, the "AC/DC" in the name is not decoration: it reflects two published component documents that together define the territory.
Reading the Name Word by Word
"Fundamentals"
This is a Level 1 credential. The word signals entry-level technical competence: reading schematics, building simple circuits, using meters correctly, applying Ohm's and Kirchhoff's laws, and locating basic faults. It does not signal advanced power-systems design or controls programming.
"Electricity"
The subject is electrical principles and practice, not electronics theory or software. The topic lists lean toward things a technician touches: wiring, instruments, relays, motors, panels, fuses, and distribution.
"AC/DC"
The slash joins two component curricula. Festo publishes one sheet for Fundamentals of Electricity - Direct Current (DC), document 272395, and another for Fundamentals of Electricity - Alternating Current (AC), document 272396. Both are dated EN 2025.09. Together they form the combined scope this site calls FEAD.
Why "FEAD" Is a Site Shorthand
Festo and NC3 do not market the credential as "FEAD." The acronym is simply the label we use to keep the credential's long name manageable across study pages. That is worth knowing for two reasons:
- When you check your school's registration or NC3Certs listing, look for the full credential name rather than the abbreviation.
- Third-party content that uses "FEAD" for other credentials has no bearing on this one. Fees, dates, pass rates, and salary figures from those sources do not apply here.
For a broader orientation to the credential itself, our overview pages on FEAD certification and what FEAD certification is go deeper on how the program fits together.
What "DC" Covers: Domains 1-18
Domains 1-18 on this site reproduce every item under "Industry Recognized Certification Topics" in the DC component sheet. The DC sheet lists 10 units and 10 labs. Those are curriculum quantities, not exam question counts or timers.
Foundations (Domains 1-5)
Safety, Electrical Engineering History, Electricity Basics, Basic Electrical Wiring, and Ohm's Law.
- Safety comes first in the list, and it recurs again in the AC half.
- Ohm's Law is the calculation backbone you will reuse in nearly every other domain.
Circuit Analysis and Measurement (Domains 6-8)
Kirchhoff's Voltage and Current Laws, Using Measuring Instruments (voltmeters, ammeters, ohmmeters, etc.), and Solving Series and Parallel Circuits.
- Expect to connect meters correctly in series or parallel as appropriate to the quantity measured.
- Series and parallel solving combines Ohm's Law with Kirchhoff's laws.
Components and Magnetism (Domains 9-15)
Basics of DC Capacitors, DC Relays, Electromagnetism, Magnetism, the DC Motor, the Solenoid, and a general Electrical Components domain (power sources, resistors, inductors, capacitors, transformers, switches, relays, motors).
- Magnetism and electromagnetism underpin relays, solenoids, and motors, so study them as a chain rather than as isolated topics.
Equipment, Resistance, and Faults (Domains 16-18)
Electrical Measurement Equipment, Electrical Resistance, and Troubleshooting Electrical Circuits.
- Troubleshooting is where the earlier domains converge: you apply laws, meters, and component knowledge to find what is wrong.
What "AC" Covers: Domains 19-36
Domains 19-36 reproduce every item in the AC component sheet, which lists 6 units and 6 labs. Again, those are curriculum quantities rather than exam lengths.
Core Concepts Revisited for AC (Domains 19-23)
Safety, Basic concepts of electrical circuits, Ohm's and Kirchhoff's laws, Using measuring instruments, and Solving series and parallel circuits.
- These mirror the DC foundations but are framed for alternating current, where reactance and impedance enter the picture.
Electromagnetism, Distribution, and Components (Domains 24-27)
Electromagnetism, Electrical distribution, Troubleshooting electrical circuits, and the Exploration of common electrical components such as power sources, resistors, inductors, capacitors, transformers, switches, relays and motors.
AC-Specific Hardware and Infrastructure (Domains 28-36)
Electricity Basics, Basics of AC Capacitors, Electrical Measurement Equipment, Basic Electrical Wiring, Basics of the Inductor, Transformers, Relays, Contactors, and Circuit Breakers, Basics of Electrical Panels, Basics of Fuses, Basics of Distribution Network, and Basics of Troubleshooting.
- Panels, fuses, breakers, contactors, and distribution networks are the practical, building-and-plant side of the credential.

Where DC and AC Overlap
Several topics appear in both lists. That overlap is intentional and reflects how Festo's two component sheets were written. The table below shows the most obvious pairs.
| Topic | DC list (Domains 1-18) | AC list (Domains 19-36) |
|---|---|---|
| Safety | Domain 1 | Domain 19 |
| Electricity basics | Domain 3 | Domain 28 |
| Wiring | Domain 4 | Domain 31 |
| Measuring instruments / equipment | Domains 7 and 16 | Domains 22 and 30 |
| Series and parallel circuits | Domain 8 | Domain 23 |
| Troubleshooting | Domain 18 | Domains 26 and 36 |
| Capacitors | Domain 9 (DC) | Domain 29 (AC) |
| Components survey | Domain 15 | Domain 27 |
What the Number 36 Does and Does Not Mean
Our "36 content areas" headline counts every item in both published component lists, including the intentional overlaps above. It is a study-mapping convenience. It is not an official claim that the exam has 36 weighted domains.
- The topic lists are unweighted. Festo does not publish percentage weights for them.
- They are preparation topics, not a formal combined-exam blueprint, and they are not proof of exhaustive exam coverage.
- An older Festo program guide for the combined Level 1 Fundamentals - Electricity credential (March 2023) lists nine certification topics. That is a historical, unweighted curriculum, not a verified current section count.
Neither does the published material establish whether a single combined examination or separate DC and AC examinations are currently delivered. We have not verified current question counts or exam-sitting durations, so we do not state any. If you want a realistic sense of difficulty without invented numbers, read how hard the FEAD exam is.
How the Credential Is Earned
The NC3Certs End User License Agreement sets out the current student rules. In summary:
- Students must receive training from an actively certified NC3 instructor at a properly equipped institution.
- Students must complete the required hands-on labs.
- Students must score at least 70% on each certification examination.
- Exams follow the issuing school's proctoring rules.
- NC3Certs access requires an active email account for two-factor authentication.
Knowledge assessment and practical lab completion are separate requirements, so passing the written side does not excuse unfinished labs, and vice versa. Student recertification is not required. The 80% threshold and three-year recertification cycle in the same agreement apply to instructors, not students. Some secondary listings, such as O*NET's entry for the combined credential, flag continuing-education renewal; that conflicts with the primary NC3 student terms, so rely on the NC3 policy. Details on scoring are in FEAD passing score.
Key Takeaway
Do not confuse the USD $500 annual institutional LMS fee in the NC3 agreement with a student exam price. It is charged to institutions, and it is waived for active member institutions. Ask your school what, if anything, you will be billed; see FEAD certification cost for how we handle this.
Scheduling also runs through your institution. Because exams follow the issuing school's proctoring rules, testing windows are set locally; our FEAD exam dates page explains how to plan around that.
Who Benefits From It
The credential is aimed at learners in technical-education programs: students at schools and colleges that participate in NC3 and teach Festo's electricity curriculum. It is an entry-level signal that you can handle basic circuits, meters, and safety practices. Employers in maintenance, electrical installation support, industrial automation, and manufacturing environments value that kind of grounding, because the domains map directly onto daily tasks: reading schematics, taking readings, checking fuses and breakers, and tracing faults.
We do not publish salary figures for the credential because none are verified for it specifically. For a qualitative discussion of career context, see FEAD jobs, the FEAD salary guide, and the value analysis.
Mapping the Name to Your Preparation
Since the name tells you the structure (DC first, AC second, shared fundamentals in both), you can sequence study to match. One simple arrangement:
Safety, basics, Ohm's Law (Domains 1, 3, 5)
- Lock in units, formulas, and safe working practice first.
Kirchhoff, instruments, series/parallel (Domains 6-8)
- Practice meter connections and multi-resistor solving.
DC components and magnetism (Domains 9-15)
- Treat relays, solenoids, and motors as applications of electromagnetism.
AC concepts, then panels, fuses, distribution (Domains 19-36)
- Spend extra time on reactance, impedance, and protective devices.
Original practice material is the best way to rehearse. NC3's agreement does not authorize copying or redistributing its exam bank, lab files, or protected instructional materials, so build your preparation from your own lab work and from independent questions. Our FEAD study guide and FEAD cheat sheet are written with that in mind, and you can check your readiness with the FEAD practice tests.
