Even with jam-packed boxes, electricians new to voice data video (VDV) cabling are not likely to have the full complement of needed tools. In addition to the usual electrical hand tools any wiring job calls for, a cabling job often requires strippers, cutters, needle-nose pliers, punch-down tools, tone and probe testers and a butt set. Typically, one crew pulls and installs the VDV wire and then another crew—generally one more technically savvy—follows behind and uses test gear for certification where required.
A first crew using good-quality tools throughout can cut down on problems for the trailing cable certifier. The quality of the termination is probably the most critical aspect of installing structured network wiring because most of the problems originate at the termination, at a block, patch panel or jack. Poor termination can result from a wire being only halfway inserted or from nicked or displaced insulation.
When installing wires from outside all the way to the point of service, numerous hand tools pass through an installer’s grip. Having tools well-matched to the task can boost productivity by enabling a job to go faster for less effort.
Manufacturers have simplified tool selection. They have put together a group of products in kits or have otherwise identified products that a certified electrician needs to get started or fully participate in VDV wiring. Even hand tools familiar in type from work in power installations, often undergo modifications to make them more suitable and effective for use in communications work. In addition, many manufacturers have refined products toward greater ergonomic efficiency, comfort, and improved performance.
When drilling into interior walls that may have metal pipes or wires behind them or into concrete, workers risk accidentally drilling into unseen materials that could either be damaged by the drill or could cause injury to the drill operator. Portable detection tools are available that can detect non-ferrous metals, such as water pipes, conduits, and electrical wires, or ferrous metals, such as rebar, to help prevent dangerous or costly mistakes in drilling.
The Hilti hand-held PS 20 Multi-Detector detects copper water pipes, post-tension cables and live electrical wires in walls, floors and ceilings, and rebar in concrete at up to a 4-inch depth range. Ergonomically designed to be lightweight and easy to use, the PS 20 is dust-protected and splash-protected, and is suitable for all weather conditions (14 to 122 degrees Fahrenheit). The tool, which features a backlit LCD display, runs on four AA batteries for more than 40 hours. To help ensure drilling accuracy, the unit features a marking sensor head that allows the operator to mark the exact location where rebar or pipe is found.
The Gardner Bender GET-4220K LAN Tracker, with adjustable sensitivity, traces unshielded and unenergized wires or cables behind walls, floors, and ceilings up to 12 inches and can distinguish between multiple wire terminations. Application-specific plugs are built into the transmitter to easily connect to coaxial cables, telephone wiring, Category 5 data cables, and unenergized electrical wiring. A warbling tone differentiates the transmitter signal from other signals. The LED intensifies as the signal gets stronger. The transmitter self-stores into the receiver and the plugs self-store into the transmitter.
Consider a kit that puts together a basic set or a more advanced set of installation hand tools. When working with fiber, installers utilize tools distinct for fiber optics, which are also available in kits.

Electricians securing insulated wire benefit from working with high-quality punch-down tools. Consistency in the quality of the spring tension in a punch-down tool is vital, to facilitate trouble-free quality terminations. Continued sharpness of the blade is also important. Some punch-down tools have high- and low-impact settings. With the high-impact setting, a user can terminate and cut the excessive wire quickly and easily. Some workers, however, do not have the strength to push down on the high-impact setting and opt for the lower-impact setting.
