danaloube - here is my builder's response to your question: "We used a seal tight cable between the receptacle box in the drawer and a junction box mounted on the wall behind the drawer. It took some time to get the loop the right length so the drawer would operate correctly." I hope this is helpful!

Thank you

Dana, Sealtight is a conduit, not a cable. This installation is not code compliant because any wires rated to go inside conduit are not rated to be used with Moving equipment. Stranded wire for conduit is meant to be "flexible" only. If flexed too many times, the wire insulation cracks and starts to spark. The only wire rated for a "moving part" is part of a "cord assembly" (think extension cord). Cords, however, are not allowed as permanent wiring or for longer than 90 days.
If there was a way to do this, many companies would be marketing products made specifically for this, because it is in high demand. So far, no design has passed UL, or NEC standards.

Fred, thank you for the info! We had many "issues" on this job and it was that last time I used that contractor.

On a more recent project (where my role was strictly organizing/not designing), the contractor installed similar outlets in drawers. I'll have to find out what his method was.

The only reason these "pass inspection" is that the inspector has not taken the time to think about it. It is one of the major reasons why we are required to put arc fault breakers on practically EVERYTHING now.
