INDOOR LIGHTING Basic DIY skills are needed to install the new wiring. Connecting things up takes electrical skills and technical knowledge, so if you are in any doubt, employ an electrician. Always ensure that the power supply is switched off before starting any work on your home's lighting circuits. It is not sufficient to turn off individual light switches. These instructions comply with the requirements of the current IEE wiring regulations. Get more from your indoor lighting by replacing old lights, installing some extra ones and putting in a dimmer switch or two. Many homes still have only the most basic indoor lighting, with a central pendant lamp-holder or some other type of ceiling-mounted light fitting in each room, plus a plugged-in table lamp or two for extra task or background lighting. Putting up new light fittings in place of what you have can make a big difference to the way a room looks. So can adding extra lights and replacing existing on-off switches with dimmer switches. 2 - Check out your system Before you start changing the light fittings you already have, or planning where to install new ones, take a little time to examine your lighting-circuit wiring so you are aware of what is involved in working on it. Turn off the power to each circuit at the fuse box or consumer unit, then unscrew the cover on one or two ceiling roses. Modern ceiling roses have a bank of terminals on their baseplates, and there will be at least two and probably three cables present (1). The circuit cable loops into and out of each rose in turn, terminating at the last rose o the circuit. A switch cable is wired into each rose and run down to the switch that controls it. This is known as loop-in wiring. f s Older roses have just one cable present, and are supplied from a junction box close by in the ceiling void into which

the switch cable is also connected. This is known as junction-box wiring. You may find that some modern roses have only one cable present; they are also supplied from a junction box, usually to save on long cable runs if the rose and its switch are a long way apart. Make sure that the lighting circuit cable has an earth core. The circuits in older houses were wired up using cable with no earth core, and one will have to be added if this is found to be the case - a job for a professional electrician. If you find old cable with rubber sheathing, do not touch it. It is probably brittle and dangerous, and needs replacing - again by an electrician.
