What type of spa requires GFCI protection or SPGFCI protection for its outlet supply according to code?

According to the National Electrical Code (NEC), both field-assembled and self-contained spas or hot tubs require ground fault circuit interrupter (GFCI) protection. This requirement is in place to enhance safety by minimizing the risk of electric shock in wet or damp environments, where these types of installations are typically located.

Field-assembled spas, which are constructed at the installation site, and self-contained spas, which come as a complete unit with all components integrated, share the potential hazards associated with water and electricity. Consequently, the NEC mandates GFCI protection to ensure that any ground faults are detected and interrupted quickly, providing an essential safeguard for users.

By requiring GFCI protection for both types of spas, the code helps to create a safer environment, taking into account various installation conditions and ensuring comprehensive safety coverage across different designs of spas and hot tubs.
