The Voltage Valet Grounded Adaptor Plug modifies the electrical sockets to accept North American and foreign appliance plugs. This ground collar is required to complete the ground connection when using model SP2 EuroSurge Surge Protector or a Continental Europe appliance plug with any of the Grounded Universal Adaptor Plugs.
Do I need a grounded adaptor? If your North American appliance plug has two flat blades and one round pin, your appliance is grounded.
