🔌🏡 Shocking Origins: How GFCIs Were Invented
In this episode we explore how, in the 1950s, researchers even used college students to test electrical shock thresholds and discovered the importance of milliamps for safety. That research led to ground-fault circuit interrupters (GFCIs), devices designed to trip quickly at specific current levels to prevent harm.
The episode explains how GFCIs protect most people—often shutting off before a shock is felt—but also notes that very small children with less body mass can still be vulnerable if exposed to electricity without a properly functioning GFCI.
