Structured wiring specialists test to confirm cabling is properly connected and operating to specifications. It is often necessary to trace a cable’s route, as well. A tone and probe kit is the tool for that job. It can trace wires inside walls, under floors and above ceilings.
Safety practices dictate that power lines and equipment must be de-energized before electricians can work on them. Only qualified people are permitted to work on live circuits under special circumstances, and they must use proper safety protection and equipment, which includes insulated tools.
Large projects require power cable pullers to get the job done quickly, efficiently and with minimal physical labor. The equipment’s basic components are the frame, power source, capstan, pulling rope and mechanism that rotates the capstan.
With the increasing use of fiber optic cable in structured wiring, many electricians experienced in low-voltage copper work are extending their skills to include fiber. Working with fiber requires training and the right tools and testers to correctly install and maintain fiber optic cable.
Ladders have been in use for thousands of years. A quick Google search of “first ladder” returns information about a Mesolithic rock painting at least 10,000 years old, the first historic evidence of a ladder. The image depicts two people using a ladder to reach a wild honeybee nest.
The impact of Brushless motors on electric hand tools is reminiscent of the transformation following the 2005 introduction of the lithium-ion battery, which, at the time, was heralded as the most significant development in power tools over the previous 20 years.
Electric motor failure can cause numerous problems, ranging from inefficient power use, equipment damage and costly downtime. In the worst-case scenario, it can result in a catastrophic fire.
Amprobe Business Unit Manager Jarek Bras said excessive heating is a common cause of motor failure.
Whether new construction or repair and maintenance work, integrated systems contractors sometimes require temporary, portable power sources. Today’s portable generators are more compact, more powerful, quieter and easier to use than ever before.
Keeping track of tools—whether just a few or hundreds—is a challenge that computers have made much easier. Software developed specifically for managing tools and equipment has replaced simple lists and spreadsheets.
The Light-emitting diode (LED) seems to be everywhere, including in tiny keychain flashlights, conventional flashlights that emit powerful beams, general service lamps, replacement fixtures for commercial use, and portable work lights.
At one time, a toolbox was just a metal box. Then, plastic and composite materials came along. Whatever the material, it remained a box, perhaps with a pull-out tray to hold smaller items. But what about portable containers for accessories and supplies?
The list of hand tools that are essential to electricians has mostly remained unchanged over the years. Cable cutters and strippers, linemen’s pliers, screwdrivers, crimpers, and other basic tools always are on belts or in pouches or toolboxes.
