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.

Sincerely,



LINDA R. ANKU
Regional Administrator
