Im trying to add a subpanel to my main breaker box, I know that on a subpanel neutral bus and ground must not be bonded, but looking inside the main panel I don't see where the neutral and ground bars are bonded, also this panel does not have connection to a ground rod, the ground rod connection it's coming out of the meter box, Its this ok? can the neutral to ground bonding be inside the meter box? , thanks in advance for the help!
