At last she traced the arc not to the breaker itself but to an aging cable whose insulation had cracked inside the conduit, rubbing only when a certain motor started and sent a slight vibration through the frame. It was a microscopic betrayal, invisible unless you listened for it. The handbook had a flowchart for such hidden faults: "If intermittent arc with motor-dependent trigger → check harness and vibration coupling." Naima switched on an oscilloscope, watched the waveform flower, and saw the murder of steadiness: a spike coinciding with the motor's inrush. : Includes detailed sections on industrial switchgear, motor
