<font color="blue"> This requires a three wire cable with ground, a floating nuetral bus bar and proper grounding, plus disconnects at each end of the feed. </font>
Just to clarify what you are saying...
By a "floating neutral" you are referring to the neutral bus bar in the sub-panel being connected to the neutral bus bar in the main panel, and the ground bus bar in the sub-panel being connected to the ground bus bar in the main panel. The sub-panel neutral should NOT be connected to the sub-panel ground at the sub-panel as is done in the main panel. Basically, the "grounding screw" in the box of the sub-panel is not installed thus allowing the neutral bus and the ground to remain seperate.
