Journeyman Exam Prep — NEC Calculations
The journeyman exam is the gateway to real money. This lesson covers the calculation categories the exam emphasizes — service calcs, conduit fill, motor circuits, and voltage drop — with worked examples.
Three-Phase Power & Industrial Systems
Three-phase is the backbone of commercial and industrial work — and the high-paying side of the trade. This lesson covers wye and delta, motor wiring, transformers, and the math that distinguishes journeymen from masters.
Solar PV, Battery, & EV Charger Integration
Renewable interconnection is where modern electrical is heading. This lesson covers PV system design, battery backup, and EV charger installation — at the depth required to take on the work that will pay above $200K/year by 2028.
Running an Electrical Business — Margins, Crews, & Specialty Work
Most electricians plateau at $80K. The ones who break $300K+ operate businesses, not just jobs. This lesson covers margins, hiring, specialty work tiers, and the financial discipline that keeps the lights on in winter.
