A floating neutral is a transformer generated current carrying conductor such as a 277/480vac 4 wire Wye configuration with the center of the Wye center tapped. The voltage from leg A to any leg is 480 from any leg to neutral is 277 and from any leg to ground is 277 (yep 277) the reason for this is that the incoming line has a static ground that provides primary grounding and if you are at ground potential you are the one who receives the shocking return. ......A floating neutral has no direct connection to ground and is generally used for in house motor operators or control or in house lighting.
Good luck from the E......

A floating neutral is one not connected to the ground.
This is a feature of isolated systems often used in medical facilities for safety, (with appropriate monitoring equipment).
The advantage is that at the first fault, there is no, (or very low), potential to ground.
The disadvantage is that if the first fault goes undetected, the potential to ground elsewhere on the system is hard to predict.

a floating neutral, is likely ungrounded, or with no reference to ground, in other words not bonded at the transformer.
