specialized construction work that is performed during the erection or reconstruction of buildings or structures intended for various purposes and that entails the installation of electric wiring and electrical equipment. The electric wiring may be overhead power lines, cable lines, current leads, or interior wiring. Examples of electrical equipment include electric machinery, distribution centers, and control consoles. In the USSR, electrical installation work is usually carried out in two stages.
Some old homes were designed to run off less power than the modern home. Most states have a 100 amp minimum requirement. Homes running under that service could consider an upgrade to bring them to between 100 and 200 amps, which could run upwards of $2,000. Homeowners should evaluate their power demands first. “A homeowner can have an electrician test the system with an amp meter while all the big loads are on,” says Holt. “If the draw is over 75-80 percent of the service size, you might consider an upgrade. Otherwise you should be fine.”
