GFCI extension cord

Can someone tell me how much protection a GFCI extension cord will provide when plugged into a non grounded outlet?

A GFCI extension cord will provide the same level of protection plugged into an ungrounded receptacle as it will plugged into a grounded receptacle.

Well, almost. The GFCI doesn't care whether or not the grounding exists, but grounding offers certain protection by itself that GFCI doesn't. At any rate, on a scale of 0 to 10, where 0 is the most dangerous and 10 is the safest, an ungrounded receptacle is a 0, a grounded receptacle is about an 8, an ungrounded GFCI is about an 9, and a grounded GFCI is about a 10. So the GFCI does indeed help a lot.

The GFI cord will provide the same protection as it would if it were plugged into a grounded receptacle. It will trip between 4-6ma of current.

The GFI looks for an imbalance of current between the hot and neutral wires.
