Wiring Up A Light
You should see plastic caps called wiring caps also called a wire nut with two wires running into each cap.
Wiring up a light. Untwist the fixture wires from the house wiring. This does not include the light switches which should be wired in switch wire which contains 2 red cores. Remove the old ceiling light. Disengage the wires by twisting the wiring cap until it comes free.
To complicate matters further someone may have decided to add another light perhaps wall lights somewhere and has taken a feed from your ceiling rose. Failure to do this may render your house insurance invalid and you may have difficulty selling your home. You can also buy the tools and products. The first rule here is when wiring a light fitting or chaging a light fitting if you are in any doubt whatsoever get an electrician electricity kills.
A lighting circuit can serve up to 12 x 100w bulbs. It is helpful to have someone to hold the fixture as you uncap the wires and remove any electrical tape. Use a phillips screwdriver to unscrew the mounting screws and bring down the light fixture. One wire will come from the light the other from the main electrical circuit of your house.
The lamp is wired so that the neutral black wire is connected to the neutral terminal and the live red wire is connected to the switched live terminal. Disengage your light from its wires.
