When in need of an extension cord in the office or at home, it is imperative to know that just because a particular cord is long enough, it is not necessarily the right one for the job. Paul Holstein, COO of CableOrganizers.com, offers these extension cord safety tips: 1. Classify the use of extension cords. 2. Verify that the power demand (or pull) of a device does not exceed the cord's wattage rating. 3. Do not use extension cords with cut of damaged insulation.
