The requirement for GFCI (Ground Fault Circuit Interrupter) protection is primarily associated with locations where water and electricity may come into contact, increasing the risk of electrical shock. General purpose receptacles, especially those found in environments such as kitchens, bathrooms, and outdoor areas, are particularly vulnerable due to the potential presence of moisture.

GFCI protection is designed to cut off the electrical circuit when it detects an imbalance between the incoming and outgoing current, which can occur if electricity flows through water or a person. This makes general purpose receptacles critical points for GFCI installation to enhance safety in residential wiring systems.

In contrast, components like resistors, capacitors, and transformers do not typically interface directly with the risks associated with moisture and personal safety. These components serve different purposes in electrical circuits and do not generally operate in contexts that require immediate GFCI protections like receptacles do.
