A restaurant has a 30 foot long line of booths in the middle of their floor space. The walls at the end of the row are tiled in marble. There is an existing outlet on one end and they want to place a lamp om the opposite wall. They want me to install a 35 foot long cord on the lamp so that thet can run the cord underneath the booths and plug it into the outlet. I pulled up some cushions and there is plenty of free space, safe from physical damage, near the floor.
Is there any NEC violation here?
