At least in California you can only tie the neutral to the ground in a sub-panel. The main panel has to have the neutral un-bonded to the panel. We saw a house burn up after snow pushed the main wires down to the neutral and it went through to a house with a bonded panel and you could not open the panel to try to stop anything because it shocked you. So the house went up in flames. So I now un-bond any neutral bars in the main panel whenever I see it.
I'm not sure why they allow sub-panels to still be connected. Also I've been shocked before by a neutral that had feedback. Really annoying.
