What type of receptacles is not allowed to be installed near a shower based on safety regulations?

The installation of non-GFCI receptacles near a shower is prohibited due to safety concerns regarding water exposure and the risk of electrical shock. National Electrical Code (NEC) regulations emphasize the importance of using Ground Fault Circuit Interrupter (GFCI) receptacles in areas where water is present, such as bathrooms, to enhance safety. GFCI devices automatically cut off power when they detect a ground fault, providing critical protection in wet locations.

While standard vinyl and weatherproof receptacles might offer some degree of protection against environmental factors, they do not provide the same level of safety provided by GFCI receptacles in potentially hazardous conditions. Therefore, non-GFCI receptacles are not acceptable for installation in areas near showers under safety regulations. This critical distinction underscores the necessity of adhering to electrical codes designed to minimize the risk of electrical hazards in residential wiring applications.
