Re: definition of "Objectionable Current"?
In my opinion, objection current is any current that flows over grounded paths that can be removed by an alteration to the grounding systems as permitted in Section 250.6(B). I don't think there should have to be a quantified amount. If current is measured on the grounding system, and an alteration can be made to stop the current, that current is objectionable. It doesn't necessarily need to be dangerous or not dangerous.

Re: definition of "Objectionable Current"?
From the 2005 NFPA NEC Handbook, "Section 250.6(D) indicates that currents that result in noise or data errors in electronic equipment are not considered to be the objectionable currents referred to in 250.6, which limits the alterations permitted by 250.6(C). See 250.96(B) and 250.146(D) for requirements that provide safe bonding and grounding methods to minimize noise and data errors."
