BS Numbers

BS Numbers (BS1363 – BS1362). One of the most common mistakes we see on our online quizzes, is the mixing up of BS numbers for plugs and fuses. The British Standard (BS) number for a standard 3-pin plug used in the UK is BS1363. The BS number for the fuse which goes in the plug is BS1362 – irrespective of the fuse rating.

  • Plug – BS1363
  • 3 Amp fuse – BS1362 – red
  • 5 Amp fuse – BS1362 – black
  • 7 Amp fuse – BS1362 – black
  • 10 Amp fuse – BS1362 – black
  • 13 Amp fuse – BS1362 – brown

13 Amp plugs, socket-outlets, adaptors and connection units are designed and built to a British Standard. This specifies the most common type of single-phase AC power plugs and sockets that are used in the United Kingdom. Particular characteristics of the system – not seen in many other standards – are shutters on the neutral and line (live) socket holes, and a fuse in the plug. It has been adopted in many former British Colonies and protectorates. BS1363 was introduced in 1947 as one of the new standards for electrical wiring in the UK used for post-war reconstruction. BS1363 plugs have been designated as Type G in the IEC 60083 plugs and sockets standard.

There are a number of similar plugs in use throughout the world – many of which will fit into our sockets. However, they often don’t have the specific safety features required in the UK. It is therefore important that when we carry out a ‘PAT Test’ we check BS numbers to ensure the correct plug is being used.

Don’t forget… BS Numbers BS1363 – BS1362… BS1363 for the plug and BS1362 for the fuse
