grounded outlet
Safe electrical socket
A grounded outlet is an electrical socket with three holes instead of two—the third connecting to a wire that safely channels stray current into the earth.
The grounding prevents electric shock and reduces fire risk.
Older buildings often have ungrounded two-prong outlets: We had to install grounded outlets before the home inspection.
