What will I learn?
This short, practical Alternating Current (AC) Fundamentals Course builds real-world confidence with residential 120 V, 60 Hz systems. Learn panel layouts, breakers, color codes, and room-by-room circuit distribution, then size conductors and overcurrent protection correctly. You will practice load calculations, apply essential safety rules, follow code-based guidance, and document circuits clearly for reliable, compliant home installations.
