What happens here

This instructional video features a Master Electrician Dad teaching his Apprentice Son about common commercial electrical voltages (120V, 277V, 480V) and the fundamental principles governing them, including the application of Ohm's Law to understand the relationship between voltage, current, and wire sizing for efficiency and safety in commercial electrical installations. It's a DIY project for learning and understanding these concepts.
