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.
In recent years, there has been a trend to increase functionality of many tools and testers that electricians use. The idea is that, if one tool can do multiple tasks, electricians will need fewer tools, which can mean a lighter tool belt or box.
From the time wires were first placed in protective pipes, electricians have been bending conduit to take cable where it needs to go. Early hand benders allowed pipe to be effectively bent without walls collapsing.
Electrical extension cords aren’t exactly “tools” in the traditional sense, but they are essential on many jobs to power tools and temporary lighting, for bringing power from generators to field offices, and for many other uses.
Power hand tools have advanced rapidly over the last few years, becoming more powerful, productive, lighter and easier to use. Along with other useful convenience features, most of today’s cordless drills have light-emitting diodes (LEDs) to illuminate the work area.
Crimping tools are routinely used to make connections that meet industry standards for both electrical and voice/data/video (VDV) installations of video surveillance, alarm and building control systems.
Construction in most trades uses saws to cut off and cut through various materials, and electrical work is no exception. Cordless saws continue to capture a growing share of the market, though there still are applications where corded saws are preferred.
