Wiring Circuits for Lighting and Power Points

Generally, all house wiring is done so that points of lights are connected in parallel, except for special cases like ceremonial lightings, photo studios, and dark rooms, which utilizes series of lighting increased brightness. Each circuit has its beginning connected to the fuse way in the fuse box or splitter unit, then to a switch, or separately to switches; or looped by switch feeds, then to lamp feed) and back to the neutral conductor). Multi core cables, e.g. twin or three core insulated and sheathed cables are used on surface wiring in connection with joint boxed, but single insulated core cables are used in conduits to permit easy branching with less jointings; however, the  basic circuits are the same.
