IEC 60309 (formerly IEC 309 and CEE 17, also published by CENELEC as EN 60309) is a series of international standards from the International Electrotechnical Commission (IEC) for "plugs, socket-outlets and couplers for industrial purposes".
BS 7671 only covers electrical systems with the following characteristics [5]: having a nominal voltage up to but not exceeding 1000V AC or 1500V DC for AC having a supply frequency of 50 , 60 or 400Hz , though the use of other frequencies for special purposes is not excluded.

Eurocard is an IEEE standard format for printed circuit board (PCB) cards that can be plugged together into a standard chassis which, in turn, can be mounted in a 19-inch rack. The chassis consists of a series of slotted card guides on the top and bottom, into which the cards are slid so they stand on end, like books on a shelf.
When a PCB has no components installed, it is less ambiguously called a printed wiring board (PWB) or etched wiring board. [18] However, the term "printed wiring board" has fallen into disuse. A PCB populated with electronic components is called a printed circuit assembly (PCA), printed circuit board assembly or PCB assembly (PCBA). In informal ...
BS 546, Two-pole and earthing-pin plugs, socket-outlets and socket-outlet adaptors for AC (50–60 Hz) circuits up to 250 V is an older British Standard for three-pin AC power plugs and sockets. Originally published in April 1934, it was updated by a 1950 edition which is still current, [1] with eight amendments up to 1999. BS 546 is also the ...
