Sockets are on 32a ring circuits in most house installations. These use a hoop of cable (ie a loop), so that at the cu 2 cables are related to the mcb instead of 1. A limiteless wide variety of sockets can be related on each ring.

Filament lamp disasters can trip mcbs, so fuses have an advantage over mcbs for lighting fixtures circuits, as they rarely nuisance ride on bulb failure.

Until the introduction of the 17th edition of the wiring regulation, sockets were now not authorized in a rest room in any respect, until they had been both a transformer remoted shaver socket, or sockets to electricity greater low voltage devices, each of which might be authorized in sector 2 or outdoor.
