Shut off power to the electrical outlet or wires you are connecting the chandelier to in the concrete ceiling. Move any furniture from under where the chandelier will hang. Put a drop cloth on the floor under the installation area to catch falling concrete dust.
Put on eye protection and a dust mask. Drill pilot holes into the concrete ceiling with a masonry bit. Insert anchors into the pilot holes and hammer in flush with the ceiling using a rubber mallet. Secure the mounting bracket to the pilot holes using retaining screws and a screw gun.
Ask an assistant to hold the chandelier while you connect the electrical wires. Wrap the ground wire around the ground post on the mount. Twist the positive and negative wires together. Secure both wires with wire nuts. Fasten the chandelier to the mounting bracket with screws or by turning it into the mounting bracket. Let the chandelier down easily and steadily. If installing the chandelier in the dining room, hang the chandelier 30 to 36 inches above the dining room table.
Ask your helper turn the power back on and light the chandelier to test. Remove the ladder, drop cloth and replace the furnishings underneath the newly installed chandelier.
