In the days of radial 5 and 15 amp circuits, the fuse was in the CU. And a
15 amp socket would often have an adaptor. With no fuse.

Interesting question: were the 15 amp sockets and 5 amp sockets on
different circuits or mixed together?

In practice? Often mixed. In theory, you'd need to find the regs of the
day. But common sense says each should have been on its own radial with
the correct fuse.

Parent's house was built new in the 1930s. Originally, one 15 amp 2 pin
per room, each on its own radial.
