History

Type G was introduced in 1947 after World War II when Britain needed to rewire the country with limited copper supplies. The design includes a fuse in each plug, distributing protection throughout the system rather than relying on central fusing.

Safety Features

Type G is considered one of the safest plug designs worldwide. Features include: built-in fuse in every plug, insulated live/neutral pins, safety shutters that only open when the earth pin is inserted, and a sturdy construction that resists damage.

Compatibility

Type G outlets only accept Type G plugs. The unique safety features mean that universal adapters are required for other plug types. The safety shutters require the longer earth pin to be inserted first to open them.

Travel Tips

  • Type G plugs are large - make sure your adapter bag has room
  • The built-in fuse can blow; carry spare 3A and 13A fuses
  • Many UK adapters are chunky because they include safety features
  • Hotels in UK-plug countries often have shaver outlets that accept Type C
