Defining Objectionable Current

Currents that introduce noise or data errors in electronic equipment are considered objectionable currents in the context of 250.6(D) of the NEC.

a) True
b) False

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."
