Abstract
In an electrical cord reel, a rotatable member can rotate about a winding axis to spool and unspool a linear material. An input power connector can couple to an electrical power source. An output power connector on the rotatable member can couple to an electrical cord at least partially wound about the rotatable member. A switch is adjustable to allow or prevent electrical current flow from the input power connector to the output power connector. In an aspect, the electrical cord reel includes an electric cord comprising a first power wire, a second power wire, and a signal wire. A method of controlling the electric cord spool system includes energizing the first power wire and the signal wire. The method further includes determining a continuity of the signal wire. The method further includes de-energizing the first power wire when determining discontinuity of the signal wire.
