Hal or Ed will correct me if i'm wrong, but an "isolated ground outlet" is a special outlet, at least here in Canada where the ground lug on the outlet is not parallel to the neutral.

If you take your meter on a normal outlet, you'll have continuity between the ground and neutral lugs. You won't with these special outlets.

These are not normally used here except for special applications as for video lottery terminals & the like.
