The Plugs and Sockets etc. (Safety) Regulations 1987
These Regulations apply to electric plugs, sockets and adaptors designed for domestic use at a voltage of not less than 50 volts and to fuse links suitable for use with such plugs and adaptors with the exception of certain electrical devices listed in Schedule 1. The Electrical Equipment (Safety) Regulations 1975 cease to apply to such plugs, sockets, adaptors and fuse links. The Regulations do not apply to plugs or sockets constructed internally in appliances where the plug cannot be engaged with or disengaged from the socket without something first being done to the appliance which requires the use of tools or to the extent that it is not practicable to conform to a British Standard listed in Schedule 3 (regulation 3).
