ELECTRICAL POWER MANAGEMENT SYSTEM AND METHOD

摘要

An electrical power system and a method of managing electrical power. Some embodiments provide improved fault isolation and service continuity circuitry. In some embodiments, a first source breaker is connected in series with a first load breaker. The load breaker can include a shunt trip, and the source breaker can include an associated lockout relay. The lockout relay can be in controlling communication with the shunt trip. Each source breaker can be in power-receiving connection with a power source. A controller can close and open the breakers according to which power source can provide power.
