TRADECAIRN Electrical Learning Hub
Online electrical training and electrician exam prep.
Build electrical knowledge at your own pace. Whether you're exploring an apprenticeship, practicing electrical calculations, learning to navigate the National Electrical Code (NEC), or preparing for a Master Electrician exam, start with the right study resources for your goal.
Start here
Choose the electrical training that fits where you are.
There's a difference between learning the trade, studying for an exam, and earning a credential. These resources work alongside—not instead of—the actual pathway required in your jurisdiction.
Find out what your first day can look like, which tools to ask about, how apprenticeships work, and how to check your state requirements.

Build the knowledge you actually need.
A useful electrical study plan should combine understanding, accurate calculations, Code-book familiarity, and practice recognizing what you still need to learn.
1. Electrical fundamentals and math
Start with voltage, current, resistance, power, series and parallel circuit concepts, common units, and the difference between a formula and a safe field decision. Practice solving a problem, checking units, and explaining what the answer represents.
A simple check: For an ideal 120-volt circuit with a 20-ohm resistance, Ohm's law gives current of 120 ÷ 20 = 6 amperes. Real installations also involve factors such as equipment ratings, installation conditions, and applicable codes; this example is math practice, not a design or safety approval.

2. NEC navigation, not just memorization
Practice identifying the subject of a question, locating the relevant NEC article or table, reading exceptions and definitions, and checking whether the adopted Code edition and local amendments affect the answer. You should know where the requirement comes from—not just remember a multiple-choice response.

3. Exam-style questions with useful feedback
Use a short practice set to find your weak areas. For each missed question, identify whether the problem was the concept, calculation, Code lookup, or time management. Revisit that skill before repeating similar questions. Longer timed sets become useful when you understand the basics and know the rules for your particular exam.

4. Learn your actual licensing pathway
Training videos and practice tests do not automatically satisfy state apprentice registration, recognized coursework, supervised experience, journeyman or master licensing, or testing-provider requirements. Before committing time or money, check the board or authority that governs the credential where you intend to work. Confirm the exam, reference editions, eligibility hours, and any approved education provider requirements.

A manageable study routine
One practical four-week starter plan.
An optional self-study outline, not an official apprenticeship curriculum or a promise that four weeks is sufficient for any licensing exam.
Take a short practice test; review electrical terms, tools, common units and basic circuit relationships. Write down what you missed.
Practice Ohm's law, power and units. Show each step and check whether your answer is reasonable.
Use your permitted NEC edition to practice finding articles, definitions, tables, and applicable conditions.
Practice timed questions where appropriate, review missed topics, and build the next study block around your weakest area.
Common questions
Before you choose an electrical training program.
Can I become a licensed electrician through online training alone?
Generally, online independent study by itself is not enough. Depending on your jurisdiction, you may need registered or approved training, supervised on-the-job hours, examinations, an application, or other qualifications. Check the licensing authority and whether a particular school or apprenticeship provider is officially accepted for the credential you want.
Does TRADECAIRN award apprenticeship hours, school credit, or a license?
No. TRADECAIRN's public resources and study applications are independent learning and exam-preparation tools. They do not grant government licenses, academic credit, registered apprenticeship completion, or supervised work-hour credit.
What is the difference between Apprentice Pro and Electrical Journeyman Pro?
Electrical Apprentice Pro focuses on foundational learning and apprentice-level NEC, calculations and exam-style practice. Electrical Journeyman Pro is the TRADECAIRN product name for advanced Master Electrician exam preparation. It is not marketed here as a stand-alone journeyman licensing course.
Can I try TRADECAIRN before paying?
Yes. Start with the free electrical practice test, the free math questions, and the NEC study guide. To explore the currently included paid study tools, check the Pro Pack seven-day no-card trial and its current terms.
Which NEC edition should I study?
Use the Code edition and amendments required by the actual licensing exam or authority you are preparing for, and confirm permitted references and whether the test is open-book. Requirements can differ from the Code edition adopted for electrical installations in your area. See our NEC exam study guide for the lookup process.
Try a short skills check, get familiar with the NEC, or explore a paid preparation product. No paid product can promise exam passage, a license, or approval by your local licensing authority.
