ABSTRACT
The majority of outlets to be used for power services are socket outlets of the types described in Chapter 1. The various ways in which power circuits can be arranged have been described in Chapter 5. It is usually found that as soon as more than two or three socket outlets are to be supplied, it is more economical to serve them from ring circuits than from radial ones. On ring circuits, only 13 A BS 1363 socket outlets should be used in order to ensure that the plug must be of the fused type and that the appliance and flexible cable to it do not rely on the ring-circuit fuse for protection. There is little more one can add about socket outlets and it remains in this chapter to say something about connecting fixed appliances and larger equipment.
