Floating vs bonded neutral
A bonded-neutral generator connects its neutral to the frame (its own ground); a floating-neutral generator leaves them separate, expecting the building’s panel to provide the bond. The wrong pairing with a transfer switch can trip GFCIs or defeat ground-fault protection.
When a generator feeds a house through a transfer switch that does not switch the neutral, the panel’s existing neutral-ground bond serves the system — a floating-neutral generator is the correct match, and a bonded one creates a second bond and nuisance GFCI trips.
Used standalone with extension cords, a bonded-neutral design is what OSHA expects on work sites. Check the spec sheet or the plate near the outlets; some models have a switchable bond. This is exactly the kind of detail worth confirming with the electrician who installs your inlet.
