notes: label: Description (Brief)
content: Original part of Trunk Line formed of naked copper wire, bound together with tarred cloth. One end had 3 strands of wire, other end shows 7 strands (#8 B&S gauge) - indicating a splice in a power line. Hinds noted: "One of our earliest experiences was to have a plumber, who was working in the building, accidentally lay a file across the two main conductors, which were uncovered, causing all the lights to go out instantly. The cause of the trouble was disclosed by the discovery of sparks coming from the crossed connection." (This was a 55 volt system.) Used in the Hinds-Ketchum printing plant as part of the first commercial installation of the Edison lighting system.
