Currents that introduce noise or data errors in electronic equipment are considered objectionable currents in the context of 250.6(D) of the NEC.
See answer and applicable Code reference
The correct answer is: b) False
The topic of objectionable current is covered in Sec. 250.6 of the 2014 NEC. However, as noted in Sec. 250.6(D), "The provisions of this section shall not be considered as permitting electronic equipment from being operated on AC systems or branch circuits that are not connected to an equipment grounding conductor as required by this Article. Currents that introduce noise or data errors in electronic equipment shall not be considered the objectionable currents addressed in this section."
