using coleman ground fault extention cord with portable generator

[bregitta]

Does the Coleman ground fault extention cord require my portable generator be grounded?

GFCI devices don't 'need' a ground to work (normally). They measure the current between the hot and neutral only, ground is not in the circuit. If the current returning doesn't match that going out, it trips. I suppose, they could design the cord to only work if it has a ground, but it is not required. From a maximum safety viewpoint, having a ground is good. Can't say on that particular device.
