Claims

[Scope of Claim for Utility Model Registration] (1) Provide a supply status detection sensor that detects the supply status of supplies that are automatically supplied to each consumer through wiring or piping, and the supply status detection sensor A forget-to-turn-off indicator that lights up when the output from the switch exceeds a preset value corresponding to the preset forget-to-turn-off prevention supply amount, including zero, should be placed at least in a location where the consumer can see it when going out, near the entrance and exit used when going out. A forget-to-cut prevention device, characterized in that it is provided so that it can be attached to. (2) The supply status detection sensor connects to the L phase of the load side terminal of any branch switch of the distribution board equipped with branch switches for each load circuit to supply power to each load circuit, and detects the load current. A current transformer that generates a corresponding output, and lights up when the output from the current transformer exceeds the set value corresponding to the preset forget-to-turn-off load current, including zero. The forget-to-turn-off prevention device according to claim 1, characterized in that a forget-to-turn-off indicator is provided separately from the distribution board. (3) The forget-to-turn-off prevention device according to claim 2, wherein the branch switch can be turned off at least by a remote control switch attached to the forget-to-turn-off indicator. (4) The forget-to-turn-off prevention device according to claim 1, wherein the supply status detection sensor is a water meter that generates a pulse output corresponding to the flow rate. (5) The forget-to-turn-off prevention device according to claim 1, wherein the supply status detection sensor is a gas meter that generates a pulse output corresponding to the flow rate.
