Device for temporary grounding of circuit breakers in residences, has internal contacts added in sufficient amount for grounding distribution networks in downstream of residences, and power grid for checking presence of exception in system

NOVELTY – The device has a power grid (11) for checking the presence of an exception in a system. A distribution network assumes a ground state (12) when the exception is identified. The network remains in on-state when a system determines information drive (13). The network remains in ground state when the information drive is not identified. Internal contacts are added in a sufficient amount for grounding the distribution networks in the downstream of residences. USE – Device for temporary grounding of circuit breakers in residences, commercials and industries. ADVANTAGE – The device is simple, efficient and inexpensive. The method enables integrating types of circuit breakers e.g. monopolar, bipolar, tripolar or tetrapolar by operating in specific voltage and current ranges and avoiding expensive switches during under load operations. The over-current protection can be performed by over-current detection techniques. DETAILED DESCRIPTION – INDEPENDENT CLAIMS are also included for the following: (1) a system for temporary grounding of circuit breakers (2) a method for temporary grounding of circuit breakers. DESCRIPTION OF DRAWING(S) – The drawing shows a front view of a grounding device. Power grid (11) Ground state (12) Information drive (13)
