Surge protectors with grounded socket

Grounded socket

— one or more European type F sockets with metal grounding clamps on both sides at the edges of the socket. The "socket" in this case means a CEE 7/4 («Schuko») standard plug. Grounding is required for the safe operation of some types of electrical appliances, in particular, washing machines and other machines that work with water, refrigerators, computers, audio equipment, etc. A detailed list can be found in the reference literature. If you plan to connect such devices through the surge protector, this surge protector must have grounded sockets.
