Prepare the wires in the outlet and ceiling boxes. The presenter uses '14/2 wire,' which means it contains two 14-gauge insulated wires (one black 'hot' and one white 'neutral') and one bare 14-gauge ground wire. First, carefully strip the outer sheathing from each wire, ensuring at least 8 inches of insulated wire extends into the box. Then, connect all bare copper ground wires together using a pigtail (a short piece of wire connected to the main bundle, which will later connect to the outlet/light fixture). Next, cut all wires so there is at least 6 inches sticking out of the box (this is usually a minimum code requirement). Finally, carefully fold the prepared wires neatly back into the box to protect them until the devices are installed. For ceiling lights, many modern fixtures come with pre-attached pigtails, simplifying this step; simply strip the sheathing, splice the wires (hot to hot, neutral to neutral, ground to ground), and fold them into the box.
