I retired a few years ago and very concerned while on vacation in Md. The hotel that we ( including grandkids) always stay out have installed 2 vending machines within 13' of edge of outdoor hot tub. Neither have GFCI devices that I thought was.required within 18" of 120 volt plug. The large hospital that I retired from 3 years ago all had the cord GFCI'S near plug. They both plug into their own 25' extension cords. Can anyone let me know if this is against the NEC. Do older machines have a grandfather clause that does require such an important safety device.Thanks. Intend to visit the local L&I concetning this.
