I bought a new clothes washer, and the plug in is 8 inches short the receptacle, so I found a short extension cord that is 3 prong, and the same gauge as the cord for the washer, and it works fine. The manual (yes, I even read it) said to NEVER USE AN EXTENSION CORD! Why not if it is rated the same as the cord for the washer, and it is short (4 feet long) so I am not losing juice over a long distance? Anyone see a problem with this? It is easier to do this then cut the drywall, put in a new receptacle when it is only 8 inches short? I cannot move the washer closer to the wall as the dryer is in the way. Thanks for the input.
