Power air circuit breakers cannot be closed safely on energized circuits by direct manual operation because the force and speed required may, in the case of fault current, exceed the strength of the operator. But in some small installations, manual operation is very desirable. A device is here described, which stores manual work in a spring in easy… CONTINUE READING
