There is also junction container wiring which is largely the same as the ceiling rose machine except there is no local connection to a lamp - so its higher appropriate to faraway lamps like wall lighting. All mixtures of those can exist on the same circuit if important :.
Filament lamp screw ups can journey mcbs, so fuses have an advantage over mcbs for lighting fixtures circuits, as they rarely nuisance journey on bulb failure. (Much less sensitive kind c and d mcbs can frequently be used to assist reduce this hassle.).
