I don't think it makes sense. With no connections to the other pins (+ve and -ve DC out I assume) then there is no DC (or AC) path through the rectifier, whatever the input, at least one diode is reverse-biased. Unless you are depending on the diodes to break down in a controlled way (and I can't believe it depends on that) then the bridge will do nothing. -tony
