International Plug & Socket Compatibility

Compare every international plug with every socket to see whether it fits directly, makes an earth connection, requires an adaptor or should not be used.

Compatibility Key

Compatible: Compatible
Incompatible: Incompatible
No earth connection warning: The plug fits, but the intended earth connection is not made. It is unsafe for appliances that require earthing.
Incorrect fit warning: Plug can be inserted but the pins are of incorrect size resulting in poor fit, which can be dangerous.
Older plugs information: Dedicated type E and type F plugs have been mostly phased out in favour of the hybrid type E/F, which is now common.

In addition to the above cross compatibility can be affected by individual socket design. This is particularly true of type E and F plugs that may not be able to fit into some recessed sockets safely due to the bulky body of the plug, even though their pin configuration may be technically matched.
