The Midget Gauge was rated at 3 A, the Standard Gauge rated at 5 A, and the Union Gauge rated at 10 A. Also offered were two-way and three-way "T pieces" or multi-way adaptors for the 3 A and 5 A plugs, two-way only for the 10 A. Versions of the concentric plug and socket were now offered rated at 5 A and 10 A. At the same time Lundberg were offering the 2.5 A Dot, 5 A Universal, and 15 A Magnum, and Tucker were offering a range of 5 A, 10 A and 20 A plugs and sockets. The sockets for this plug are rated at (and limited to) 200 mA. There are four ratings of plug and socket in BS 546, (2 A, 5 A, 15 A and 30 A). 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). This plug was also once used in theatrical installations for the same reasons as the 15 A model below. The larger top pin is the earth connection, the left-hand pin is neutral and the right-hand pin is line when looking at a socket or at the rear of a plug.

Side contact is not much better than top contact but at least it is less exposed. The biggest advantage to digital cable telephone service is similar to the advantage of digital cable, namely that data can be compressed, resulting in much less bandwidth used than a dedicated analog circuit-switched service. A submarine communications cable is a cable laid on the seabed between land-based stations to carry telecommunication signals across stretches of ocean and sea. Based on surveying breaks in the Atlantic Ocean and the Caribbean Sea, it was found that between 1959 and 1996, fewer than 9% were due to natural events. When installed in wet areas (e.g. bathrooms), for safety reasons it is normally found incorporated into a shaver supply unit which includes an isolation transformer and meets various mechanical and electrical characteristics specified by the BS EN 61558-2-5 safety standard to protect against shock in wet areas. The BS 4573 socket is for use in rooms other than bathrooms.

This 5 A plug, along with its 2 A cousin, is sometimes used in the UK for centrally switched domestic lighting circuits, in order to distinguish them from normal power circuits; this is quite common in hotel rooms. It is the largest in domestic use and is commonly used in the UK for indoor dimmable theatre and architectural lighting installations. The 30 A plug is the largest of the family. This plug corresponds to Type D in the IEC table. This plug corresponds to Type M in the IEC table. Use of the BS 546 30 A plugs and sockets diminished through the 1970s as they were replaced with BS 4343 (which later became IEC 60309) industrial combo plugs and sockets. The whale was apparently attempting to use the cable to clean off barnacles at a point where the cable descended over a steep drop. • Bandwidth The effective capacity of twisted pair cable depends on several factors, including the gauge of the conductor, the length of the circuit and the spacing of the amplifiers (repeaters). In the UK it was used for moderate sized appliances, either on its own 5 A circuit or on a multi socket 15 A circuit, and also on many adaptors (both multi socket 5 A adaptors and adaptors that also had 15 A pins).

This was used for high power industrial equipment up to 7.2 kW, such as industrial kitchen appliances, or dimmer racks for stage lighting. The Funitel is a fast, detachable-grip gondola that offers a comfortable ride and high wind stability. Also in 1934 the 10th Edition of the IEE's "Regulations for the Electrical Equipment of Buildings" introduced the requirement for all sockets to have an earth contact. The first British standard for domestic three-pin plugs was BS 317 Hand-Shield and Side Entry Pattern Three-Pin Wall Plugs and Sockets (Two Pin and Earth Type) published in 1928. This was superseded in 1930 by BS 372 Side-Entry Wall Plugs and Sockets for Domestic Purposes Part II which states that there are only minor alterations from BS 317. In 1934, BS 372 Part II was in turn superseded by the first edition of BS 546 Two-Pole and Earthing-Pin Plugs and Socket Outlets. The first commercial AC distribution system entered service in 1885 in via dei Cerchi, Rome, Italy, for public lighting. BS 73 Wall plugs and sockets (five ampere two-pin without earthing connection) was first published in 1915, and revised in 1919 with the addition of 15 A and 30 A sizes. BS 4573 British Standard Specification for two-pin reversible plugs and shaver socket-outlets defines a plug for use with electric shavers.
