A safety plug is designed to prevent electrical accidents by interrupting the flow of electricity to devices when a problem occurs. Synonyms for safety plug include ground fault circuit interrupter (GFCI), residual current device (RCD), and circuit breaker. GFCIs are commonly used in bathrooms, kitchens, and outdoor areas to prevent electrical shocks and electrocutions. RCDs are typically used in construction sites and industrial settings to prevent electrical accidents. Circuit breakers, on the other hand, are used to protect electrical systems from overload by shutting off power when the current exceeds the safe limit. Synonyms for safety plug may vary depending on context and region, but they all serve the same purpose of keeping people safe from electrical hazards.
