A variant of the Australian standard 10 amperes plug has a socket on the back to allow connection of a second appliance to the same outlet.

BS 4573 British Standard Specification for two-pin reversible plugs and shaver socket-outlets defines a plug for use with electric shavers. The pin dimensions are the same as those of the 5 A plug specified in the obsolete BS 372:1930 part 1 (as shown in the table above).

A plug is the connector attached to an electrically-operated device, often via a cable. A socket (also known as a receptacle or outlet) is fixed in place, often on the internal walls of buildings, and is connected to an AC electrical circuit. Inserting ("plugging in") the plug into the socket allows the device to draw power from this circuit.
Portable classrooms are colloquially known as bungalows, slum classes, t-shacks, trailers, terrapins, huts, t-buildings, portables, mobiles, or relocatables.
