The NEC Navigation Method: Find the Path
Classify → Article → Section → Answer.
Start here — even if you've been in the trade for years. Fast electricians don't memorize the NEC. They know the shape of the book, the neighborhood each article lives in, and how to move from a job-site question to the exact section in under a minute. That's the skill this course builds.
Residential Wiring Foundations
From service panel to the last outlet on the run.
Before you pull a single wire on a real job, you need to read a panel, size a circuit, and know which color goes where. Skip this and you create fire risk.
Troubleshooting Live Circuits
Find the fault without becoming the load.
Diagnostic work is where journeymen earn their rate. Knowing how to isolate a fault in under 10 minutes is the difference between a happy customer and a callback.
Motor Calculations: From FLA to the Licensing Exam
The one topic that shows up on every journeyman and master exam.
Motor problems are the highest-point-value questions on most licensing exams. Nail the FLA → conductor → OCP → disconnect path and you gain 15–20 points.
Grounding & Bonding Fundamentals
Grounded, grounding, and bonded — three words that are not the same thing.
Grounding and bonding questions are everywhere on the exam and everywhere in the field. Confuse a grounded conductor with a grounding conductor and you'll miss the point of Article 250 entirely.
Load Calculations (Article 220)
3 VA per square foot is the number that starts every dwelling calc.
Load calculations show up on nearly every journeyman and master exam, and they're worth big points because each problem chains several sub-answers together. Miss step one and the rest falls apart.
Overcurrent Protection (Article 240)
Breakers and fuses exist to protect the wire, not the appliance.
Every branch circuit, feeder, and service depends on correctly sized and correctly located overcurrent protection. This is foundational Article 240 material that shows up from the apprentice exam all the way through master.
Services (Article 230)
Where the utility's wires stop being the utility's problem.
Service work sits at the intersection of code, utility rules, and safety — get the disconnect count, minimum size, or clearance wrong and you fail an inspection (or worse).
Conductor Ampacity & Derating (310.15)
The wrong column of Table 310.16 will fail you before you even leave the classroom.
Ampacity and derating questions are pure code-book navigation combined with arithmetic — master the table and the adjustment factors and these become the fastest points on the exam.
