In Ireland, the National Standard is I. BS specifies requirements for 13 A fused plugs having insulating sleeves on line or always quoted as live and neutral pins, for household, commercial and light industrial purposes, with particular reference to safety in normal use.

The plugs are suitable for the connection of portable appliances, sound-vision equipment, luminaries, etc. Requirements are specified for plugs incorporating a fuse link complying with BS The plugs may be rewirable or non-rewirable complete with flexible cord. Two categories of plugs are specified covering normal and rough use. The rough use plug is nearly 2 to 5 times durable than that of normal use plug in terms of dropping onto wooden floor.

Rewirable plugs are intended for use with the flexible cords complying with BS or BS EN having conductor cross-sectional areas from 0. Non-rewirable plugs or always quoted as moulded plugs are intended for use with flexible cords having conductor cross-sectional areas not exceeding 1.

BS also applies to non-rewirable 13 A plugs which have the brass earth pin replaced with a similarly dimensioned protrusion made of insulating material designated as an insulated shutter opening device ISOD designed to operate the shutter mechanism of a socket-outlet conforming to BS Plugs containing switches and devices other than indicator lamps are outside the scope of this part of BS UK plug is mechanical by nature of construction, A plug does not emit intolerable electromagnetic interference since significant electromagnetic disturbances are only generated during insertion and withdrawal which are not continuous.

Plugs and Sockets etc. Safety Regulations S. Safety Regulations the "Regulations" were introduced to provide a regulatory regime to address issues regarding consumer safety. As the Regulations are national in origin, regulating a specific product area within the scope of the General Product Safety Directive, they do not introduce a requirement to CE mark products. In UK, most electrical equipment intended for use in and around the home will need to comply with the Electrical Equipment Safety Regulations Most other Member States, however, have national legislation which ensure that any electrical equipment or appliance placed on their respective markets is fitted with an appropriate plug.

For Ireland, the Irish Standard I. It is the same for other countries, e. The fuse links used within the plugs should also need to have the similar safety approval from these countries before selling together with plugs. The purpose of the fuse link within the plugs is used to protect the Ring Circuit of electrical installation at home for overloading, and not mainly for providing protection to the electrical equipments or appliances connected. The electrical appliances are required to have their own protection according to the corresponding National Standards of the appliances.

The BS fuse link has the following characteristic :- Ring Circuit Electricity is supplied to homes by mainly line wire and neutral wire, before the two wires go into home, they are connected to a consumer unit, where the circuit breakers are located. Coming out from the consumer unit, the line wire and neutral wire branch out to form several parallel circuits, i. These parallel circuits form a ring surrounding homes, and they are called ring circuit.

The plug pins are usually brass, the live and neutral pins have a black plastic sleeving fitted to part of their length, and the cable can be secured by using the cable grip provided. Connection of Flexible Cord for UK Plugs After connecting the wires of flexible cord to the plug, the cord is required to be secured by the cable grip to the plug, in order to avoid the wire connections being loose, due to the accidental pull at the cord. The normal cord anchorage is usually done by mean of a cable grip and two screws, and the user requires a screwdriver to perform the cord connection, it may be hard for ladies and elder people, in order to overcome this and make things easier, the easy wiring on the cord connection is introduced.

We have invented and patented an easy wiring mechanism that come with the plug base marked "5" in below figure for easy production at one single process, and saving a lot of post works during manufacturing, which truly provides an easy way for the cord connection. The users only have to press the cord into the gap between the deflectable tabs marked "11" in below Figure , without using any tool, the cord is then automatically locked up by the deflectable tabs, which is applied for all sizes of allowed cords within BS The way of manufacturing on their plug pins is actually from our original innovation, and their methods used are mainly from and described within our Patent.

The maximum rating of UK plugs is 13A, that is, the maximum 13A current can flow through the plug pins and all the joints of plug pins. If something loose at the joints, a hugh energy or heat will be accumulated by electric flashover, and the plug will be burned or melted, even the fire hazard may be occurred.

In order to avoid that, a careful design at joint or making the joint very tight should be necessary. We have invented and patented a manufacturing method for good riveting between the fuse clip and the line pin, ensuring no loose joint will be located within our plugs. One factory was making porcelain electrical insulator for overhead cables and electric poles T poles , another factory was established in late 30s just only one or two years before the war and started to make bakelite products to the local market, of which, bakelite is the modern moulding material and modern industry at that time before plastic occurrence.

Porcelain Electrical Insulator Mr. Fok not only interested with the electricity, he also interested with electrical installation, especially the electrical plugs. The electrical plug that Mr. Fok to China. This also explains the mystery of why China plug looks like Australian plug, and not following UK plug, American plug or German plug design, where UK, USA and German were advanced industrial countries, and Australia was an agricultural country at that time.

In , Mr. Fok to the bakelite and to his dream. Maurice End, Mr. Fok Bun and our staff on 2nd April, Maurice End is next to him. Our present M. Lau is next to him. The middle at the front row is the daughter of Mr. Fok Bun. The photo taken at the Peak Hong Kong in April,

Right: a typical rewireable plug; the large central screw releases the cover, allowing access to the terminals and also the fuse BS is a British Standard which specifies the common single-phase AC power plugs and sockets that are used in the United Kingdom. Distinctive characteristics of the system are shutters on the line and neutral socket holes, and a fuse in the plug. It has been adopted in many former British overseas territories. One of these, the Electrical Installations Committee, was charged with the study of all aspects of electrical installations in buildings.
