Safety Device for Live Electrical Wire

[Category : - ELECTRICITY & LIGHTING]
[Viewed 714 times]

The present invention provides a safety device for protecting a person from an electrical shock while working on a live electrical wire connected to a terminal within an electric meter or circuit breaker box. The safety device comprises an inner cylinder slideably engaged within an outer cylinder and a spring disposed between the two cylinders for extending the outer cylinder axially outwardly with respect to the inner cylinder. The cylinders are made of nonconducting material. The inner cylinder engages insulation that covers the wire proximate to a bare end of the wire, which is connected to the terminal by a screw. When the person loosens the screw and the wire becomes disconnected from the terminal, the spring forces the outer cylinder outwardly to cover the bare end of the wire, which helps to protect the person from electrical shock.
