GFCI protection is not required for equipment at a carnival when a locking type receptacle is used. Locking type receptacles are designed to prevent the accidental disconnection of electrical equipment, which can be particularly beneficial in environments with a lot of movement and temporary installations, such as at a carnival. The locking mechanism ensures that the plug remains secure in the receptacle, thus reducing the chance of electrical shock from unintentional disconnection.

In contrast, standard type receptacles do not have this locking feature, making them more vulnerable in dynamic settings and therefore more likely to require GFCI protection. Grounded type receptacles could enhance safety by providing a pathway for fault current, but they still necessitate GFCI protection under certain conditions, particularly in wet or outdoor settings. Weatherproof type receptacles, while designed to protect against moisture, do not negate the need for GFCI protection in scenarios where equipment is exposed to environmental hazards, such as those found at carnivals.
