Florida has adopted the 2020 NEC as of the 2023 FBC. Check your area for details.
Outside emergency disconnect and whole house SPD (Surge Protection Device) protection now required.
New updates for GFCI protection:
210.8(A) GFCI Voltage Provisions Increased
All 125-volt through 250-volt receptacles supplied by single-phase branch circuits rated 150 volts or less to ground installed in the eleven (11) specific locations of 210.8(A) at dwelling units will now require ground-fault circuit-interrupter (GFCI) protection for personnel. Historically, this dwelling unit GFCI protection was limited to 125-volt, single-phase, 15- and 20-ampere receptacle outlets. Notice that no ampere rating is specified with the 2020 NEC requirements at 210.8(A). The addition of up to 250-volt receptacles and removing the amperage limitations of 15- and 20-amperes will provide GFCI protection to most receptacles commonly used in the specified areas of 210.8(A). The necessity for GFCI protection for areas such and kitchens and laundry areas has been proven for these receptacles over several Code cycles. 250-volt rated receptacles, such as a typical laundry room dryer receptacle, present similar shock hazards. Substantiation submitted for this change demonstrated the need for GFCI protection for greater the 125-volt rated receptacles. Including these higher-rated receptacles for GFCI protection at dwelling units is compatible with the increased GFCI protection provisions that occurred for other than dwelling units at 210.8(B) during the 2017 NEC revision cycle.
