Standards behind ordinary actions
ULSE frames switches, alarms, GFCIs and other products as examples of safety requirements operating largely out of sight. The article says a typical U.S. home contains roughly 125 products designed to meet safety standards.
UL 943 and GFCI protection
The article identifies UL 943 as the standard for GFCIs and links the device’s function to reducing electric-shock risk. This is a general standards explanation, not certification evidence for any individual model.
Evolving with technology
ULSE notes that safety standards continue to evolve as homes and devices become more connected and rechargeable. Product teams therefore need to monitor both established requirements and newer technology-specific standards.
