- * Compatible with ungrounded plugs.
- † Deep-wall socket prevents human contact with pins.
- ‡ CEE 7/7 specifies a grounded hybrid plug that will fit into both the CEE 7/4 and CEE 7/5 sockets. CEE 7/17 specifies an ungrounded hybrid plug that will fit into both the CEE 7/4 and CEE 7/5 sockets.
- 1 Type letters are from a US Department of Commerce report that sees widespread but not universal use to differentiate plug and socket types based on rough mechanical compatibility. Most common household plugs have an associated letter.
- 2 There are some CEE 7/17 plugs with special shape which are polarised when used with CEE 7/5 sockets (mechanically only).
- 3 Plug can only be inserted one way with French CEE 7/5, but lack of wiring convention means that the system is not polarized.
- 4 Newer sockets can accept ungrounded Europlugs.

Famous quotes containing the words comparison and/or sockets:
“In everyones youthful dreams, philosophy is still vaguely but inseparably, and with singular truth, associated with the East, nor do after years discover its local habitation in the Western world. In comparison with the philosophers of the East, we may say that modern Europe has yet given birth to none.”
—Henry David Thoreau (18171862)
“Webster was much possessed by death
And saw the skull beneath the skin;
And breastless creatures under ground
Leaned backward with a lipless grin.
Daffodil bulbs instead of balls
Stared from the sockets of the eyes!”
—T.S. (Thomas Stearns)
