What is the maximum cord length allowed for a listed packaged spa or hot tub installed outdoors, provided it is protected by a GFCI?

10 feet
15 feet
20 feet
25 feet

The correct answer is: 15 feet

The correct answer is based on the National Electrical Code (NEC) standards regarding the installation of outdoor spas and hot tubs. When a listed packaged spa or hot tub is installed outdoors, it is required to be protected by a Ground Fault Circuit Interrupter (GFCI) to enhance safety against electric shock. According to NEC guidelines, the maximum length for the cord connected to such equipment, when the GFCI protection is in place, is 15 feet. This length ensures that the electrical cord remains within a manageable distance while minimizing the risk of tripping hazards that longer cords could create. Additionally, shorter cord lengths reduce exposure to outdoor elements which can deteriorate the cord over time, potentially leading to electrical malfunctions. This understanding is integral for adhering to safety protocols while also ensuring compliance with electrical code requirements.
