Automakers are improving fuel economy by exploiting a new controls approach that uses the waste heat from vehicle engines. Currently, up to 65% of the heat energy produced in internal combustion engines, whether gasoline or diesel, is wasted. Typically, the powertrain or engine dissipates the heat by convection, where it is carried to the cooling circuit or lost out of the tailpipe in exhaust gases.

Electrical installation work is mechanized through the use of general-purpose construction machinery—for example, lift trucks, hoists, and truck cranes—and of specialized electrical-installation machinery, devices, and tools. The time required for electrical installation work is reduced and the productivity of labor in such work is raised primarily through the use of industrial methods of installing electrical equipment and through the delivery to construction sites of structures for the installation of wiring and elements of electric wiring in consolidated subassemblies and units, which are fabricated and assembled in electrical-installation prefabrication shops. The level of industrialization of electrical installation work is due in large part to the output by industry of complete sets of electrical equipment and of electric wiring that can be easily installed and adjusted.

In 1897, the National Fire Protection Association established the National Electric Code (NEC). The National Fire Protection Association was a group of Insurance companies that were concerned about the potential danger inherent in faulty electrical wiring. They had cause for concern. Early wire was bare or covered with cloth. There was little understanding of the need for insulation.

Among the most common projects is installing an outlet. It's a basic project that almost anyone can do if they take the time to understand the process. You may also want to understand how to wire a split outlet. This actually comes in handy if, for instance, you want to plug a lamp into an outlet and be able to turn it on from a wall switch.

"AFCI’s give great fire protection to homes with older wiring,” says Mike Holt, licensed electrician, electrical inspector, instructor, and founder of Mike Holt Enterprises, providers of educational resources to those in the electrical profession and related fields. Currently, the National Electric Code requires AFCI breakers for circuits providing power to bedrooms, living rooms, family rooms, and other common rooms in new construction. The cost for an AFCI breaker varies by manufacturer, but consumers can expect to pay around $30 to $35 apiece.

The place where a wire is joined to another wire or attaches to a device is the point where there is the most danger of a spark. It is important that connections are secure. Insulated plastic wire nuts are used to attach two wires. There are also special tools used by electricians to deal with the installation of wiring. An example is the combination wire cutter and stripper. The stripper is used to remove the insulation from the end of the wire so that the bare wire might be attached.

The first stage, which coincides in time with general construction work, includes the installation of fasteners or inserts in structural elements for the subsequent attachment of electrical equipment and structures for the installation of electric wiring. It also includes the installation of conduits for electric wiring in the foundations and floors of buildings or structures and the installation of wall sockets for outlets and switches. In the first stage, the preassembly of electrical equipment and wiring structures, the fabrication of conduit sections, and the board lacing of wires and cables for lighting and other circuits are carried out away from the construction site in specially equipped electrical-installation prefabrication shops.
