I frequently read/hear that laying a rug over an extension cord is 'bad juju', however, I can't find the specific part of the NEC, or any other code, that prohibits this practice. 2007 NEC 590.4(H)(Temporary Installations) requires that "Flexible cords and cables shall be protected from accidental damage."
There are products that are designed to protect cables (Checkers www.checkersindustrial.com, Yellow Jacket www.yjams.com, FireFly www.fireflycableprotector.com, HandiRamp www.handiramp.com/cableprotectors.htm, Hubbell TrukTrak, Electriduct Nite Hawk www.electriduct.com/Nite-Hawk-Cable-Protector.html), however, I can't find any mention of the NEC in any of the product literature, either. Are these products considered a 'raceway' or 'conduit' or 'cable tray'?
I understand that you can't run an SJO power cord through an EMT conduit because it's not rated for this application, so why can we run the same cable through a plastic cable protector? And if we can, how far can we go before it becomes an issue? Either way, the cable is in a confined space that may affect the heat dissipation. 2007 NEC 400.8(6) says ". . . Flexible cords and cables shall not be used . . . where installed in raceways . . . "
For these products (Safcord www.angelguardproducts.com/cord/safcord, Tunnel Tape / Cable Path Tape (Empire Tape Co. www.empiretape.com)) what is the difference between tape / cordura rather than 'just throwing a rug over it'?
Note of clarification: This question is NOT about running FCC cable under carpet.
