Plug types used in United Kingdom

Type G Reference shape and compatible sockets

Type G · grounded

Standard 230V at 50Hz. Type G is the large three-rectangular-pin fused plug, used nowhere on the European mainland. A US 120V single-voltage appliance plugged in here without a voltage converter will overheat and can catch fire — a plug adapter alone is NOT enough.
