I don't understand the bonding at my main disconnect. My problem is that my main panel in the house was wired OK with the neutral bonded to ground. The power company added a disconnect box below the meter box. I noticed the disconnect they installed doesn't have the neutral bonded to ground. Am I going to have a problem? From what I read my main panel is now a sub panel because they added a disconnect? I am wondering why they thought it was OK.

If the power company did not change the bonding point, you still have a main panel ("the one with the bond in it.")

So long as there's only one, the location of the bond can and does vary with the preferences of the power company, mostly. Mine is inside the meter box, so my panel is wired as a sub-panel.

On a typical panel run from a meter and bonded in the panel, the meter itself is a disconnect point that's upstream of the bond, and that's not a problem.

You should realize that the neutral and ground conductors are not interrupted by a disconnect, so the bond in your panel is still effective even with a disconnect upstream of it.

If the power company had opted to move the bond point, they would have needed to rewire your panel - a considerable expense (for them) and inconvenience (for you) they avoid by not changing the bond point.
