Three Wires in the Wall
The Electron Vacuum Cleaner Behind the Receptacle
From the essay
Most of us know the names before we know the story: Hot, Neutral, Ground. But behind those three familiar words is a small drama about paths—the path electricity is meant to take, the path it takes back, and the emergency path meant to keep it from taking you. Hot sounds dangerous, Neutral sounds peaceful, and Ground sounds as if the earth itself has joined the safety committee. But wires do not have personalities. They have jobs. The receptacle does not make electricity harmless. It makes electricity behave by giving it better paths than us.
