2017 NEC

[Hendrix]

Is there a section that requires 240vac receptacles to be GFCI protected in a residential setting?

 

[Dennis Alwon]

The 2017 only requires gfci for 120v receptacles in a residence

 

[Dennis Alwon]

The 2017 has a real change for non-dwelling

(B) Other Than Dwelling Units. All single-phase receptacles
rated 150 volts to ground or less, 50 amperes or less and three phase
receptacles rated 150 volts to ground or less,
100 amperes or less installed in the following locations shall
have ground-fault circuit-interrupter protection for personnel.
