OSHA requirements are set by statute, standards and regulations. Our interpretation letters explain these requirements and how they apply to particular circumstances, but they cannot create additional employer obligations. This letter constitutes OSHA's interpretation of the requirements discussed. Note that our enforcement guidance may be affected by changes to OSHA rules. Also, from time to time we update our guidance in response to new information. To keep apprised of such developments, you can consult OSHA's website at https://www.osha.gov.

Dear Mr Fauth:

This is in response to your letter asking whether OSHA would require a specific brand of extension cord, equipped with a built-in "continuity tester", be tested for continuity. The built-in "continuity tester" is in the form of a light embedded in the receptacle portion of the cord set. When the light is on, that means the cord is energized.

OSHA's concern for continuity, in so far as extension cords are concerned, relates to continuity of equipment grounding conductors. The built-in "continuity tester", in the cord in question, does not and cannot provide any information concerning the continuity of equipment grounding conductors.

If you require any additional information regarding the preceding, please contact John McFee of my staff at (215) 596-1201.
