Technical Guidance Document #047

Whilst European plugs do have an earth connection, this is in the form of a metal strip within the body of the plug which only connects the earth when the plug is connected to a matching socket which has an internal earth terminal that connects with the strip connector in the plug. See picture below. This means that when connected using a travel adaptor of the type shown in this case, the appliance is not earthed.
