Most commercial and industrial projects have electrical work that must be done above floor or ground level, and a wide range of push-around and self-propelled personnel lifts provide a practical alternative to ladders and bulky scaffolding, which can be time-consuming to assemble and dismantle.
Installers of today’s commercial datacom, control and alarm systems must be multitalented. They often must work with twisted-pair copper, coaxial and fiber optic cables, each requiring specialized knowledge and tools.
This is a column about tools. For technicians who install, maintain and repair components of a building’s low-voltage networks, basic hand tools include wire cutters and strippers, crimpers, punchdown tools and testers—many designed specifically for voice/data/video.
Installing and maintaining a building’s structured wiring system often means accessing locations that are out of reach from floor level, and many workers choose to use various types of scaffolding, including compact work platforms on wheels that provide a base for overhead work.
Variables affecting electric power quality haven’t changed significantly over the years, but the technological advances of electrical and electronic equipment make the equipment much more vulnerable to power quality events than in the past.
Copper remains a primary carrier for integrated building systems, but fiber optic cabling is assuming an increasingly important role in data, telephone, access controls, security cameras, fire and security alarms, sensors, and other signaling-dependent systems.
The proliferation of lithium-ion powered cordless tool models continues to hold the attention of tools buyers, including electricians. However, electricians still turn to an old staple to do theire work: manual hand tools.
The tape measure is a basic tool for integrated systems installers, electricians and professionals in many trades. It has been in use for years, but the measuring tapes available today are nothing like early versions.
The handheld power hammer drill is a basic electrician’s tool that is two drills in one—a conventional drill for working in wood and soft materials and a hammer drill for drilling 3/16- to ¼-inch holes in masonry, cinder blocks, concrete, metal and other hard materials.
