  1. Bob K says:

    Are the short 1-2 foot, 3-prong, heavy duty multiple outlet extension cords that have their own reset buttons, any safer?

    • Dave Rongey says:

      Hi Bob,
      Without knowing any details about the heavy duty extension cords you described and the application, I would say that the extension cord should be UL Listed and Approved, and only used for the Described Intended and Approved Purpose Only. We should never modify an extension cord, or use it for any purpose other that what the extension cord has been designed for, and within the limitations defined and approved by the Underwriters Laboratory.
      I hope this helps,
      Dave
