Today's houses demand wiring systems to accommodate a variety of contemporary fixtures: home-theater systems, telephone lines, and data wiring. Electrician Brian Walo outlines the tools, materials, and procedures necessary to get any house ready for convenient connections for televisions, phones, and computers. Voice and data lines require RJ45 plugs and wall plates, and use Cat5 wiring. Video lines need coaxial cable. Most installers today use the thicker RG6 variety. Be aware that coaxial cable requires special tools (cable strippers and crimpers) and four types of fittings (twist, push-on, crimp, and compression). Finally, for audio wiring, keep in mind that you need to choose the right wire gauge (check wattage ratings for speakers and the distance of the wiring run) and the proper fittings (pin, spade, or banana).
