Wiring a construction project, from a single room to a building with multiple floors, involves running wire between electrical boxes for outlets, light switches and fixtures. To adhere to electrical codes, it is important to obtain a permit, ensure that the wire is the right size and type, and drill holes deep enough to ensure that wires are not be pierced by nails or screws later in the construction process.
To wire a room, begin by placing electrical boxes (in homes, usually blue plastic boxes) where outlets and switches are to be located. Place outlets so that the space between outlets is less than 6 feet without crossing any doors. Additionally, place light switches so that they are not blocked by the door when it's opened.
Once the boxes are placed, run insulated wire (typically 14-gauge for bedrooms and living rooms and 12-gauge for kitchens, bathroom outlets, and garages) between them. Pick a starting point where power comes into the room (either from another room or directly from the electrical panel), and drill holes from there to the next outlet in the room. Holes should be 3/4 inch and drilled at hip height in the direct center of each board in the wall. Pull the wire through these holes to connect all outlets, the light switch and the light fixture, making sure to label all wires.
Have a professional inspect all electrical work, since mistakes can cause fires or electrical problems.
