My husband is new at your channel, he says he has never seen anyone or explains how 240V can be 480V from the same motor windings. Every electrician couldn't even come close to explaining the theory, which really surprised him. These commercial & industrial technicians just follow the wiring diagram not knowing how it all works inside. He now understands how this comes about and is constantly referring to your channel, finally he says someone that talks normally rather than sounding like Einstein.
