Which installation is required for all plugs in a bathroom?

In bathroom installations, the requirement for all plugs to be equipped with a Ground Fault Circuit Interrupter (GFCI) is critical for safety reasons. Bathrooms are areas with increased moisture and the potential for electrical hazards. A GFCI is designed to detect ground faults, which occur when electricity flows through an unintended path, such as water or a person. When a ground fault is detected, a GFCI quickly disconnects the power to prevent electrical shock, making it an essential safety feature in locations where water and electricity may come into contact.

While a 20-amp circuit may be necessary for certain appliances in the bathroom, and the use of a standard circuit breaker or double-pole breakers might be relevant in other contexts, the specific requirement for GFCI protection is mandated by electrical codes for bathroom outlets. This ensures that even if there were a fault, the risk of injury is minimized. Therefore, the necessity of GFCI installations in bathrooms relates directly to safeguarding users against electrical shock in wet conditions.
