Question:

Hello code friends. The use of extension cords in our office has become a bit of an issue. One example of extension cord usage is where an extension cord runs for about 10 feet from a wall receptacle to an office work station. The female end of the extension cord is connected to a power strip, under the workstation for the printer, computer and other workstation related items are plugged in. Recently a fire dept. inspector saw it during our annual fire inspection, and decided it is not a code violation because the power strip is UL Listed for that purpose. Is this type of installation allowed? Thanks Mike Stevenson

A

Answer:

Hello Mike, and thank you for participating in the CQD. In general,  use of extensions cords for the substitution of fixed wiring is prohibited by Section 400.12(1). A “power strip” is also know by the technical name “relocatable power tap”. A relocatable power tap is slightly different from a listing persepective than a typical extension cord. However, a relocatable power tap is still not intended to be used as a substitute for fixed wiring.
