What specific requirement is there for convenience outlets in bathrooms?

Convenience outlets in bathrooms must be protected by a GFCI (Ground Fault Circuit Interrupter) device due to the high risk of electrical shock in such wet environments. GFCIs are crucial in areas where water is present because they can detect ground faults and interrupt the electrical circuit within milliseconds, greatly reducing the risk of electrocution. This requirement is part of the National Electrical Code (NEC) and ensures that any outlet in a bathroom is safe for use, especially since these spaces typically have moisture from showers, sinks, or bathtubs, which increases the chances of electrical hazards.

The other choices are not applicable to the specific requirements for bathroom outlets. For example, the height requirement mentioned does not specifically pertain only to bathrooms, dimmer switches are not a standard requirement for these outlets, and convenience outlets cannot just be placed anywhere; they must comply with safety standards, including GFCI protection, to ensure user safety.
