Electrical

An introduction to the electrical trade: what electricians do and where they work, the materials and tools, electrical safety and NFPA 70E, the apprentice-to-master ladder, NEC basics for circuits, loads, grounding, and overcurrent protection, the daily sequence from prints to trim, and the specialties and career outlook.

The working electrician's second course: reading E-sheets, one-lines, and panel schedules; load calculations and service sizing; conductor ampacity, adjustment, and voltage drop; raceway, box, and fill rules; grounding and bonding built part by part; and rough-in sequencing, inspections, testing, and NFPA 70E applied on a live jobsite.
