Electricians
Electricians are required to perform multiple tasks to fit the needs of todays people. They install, connect, test, and maintain electrical systems for a variety of purposes, including climate control, security, and communications. Electricians normally will either be involved in construction or maintenance; but whichever they choose they have to stand up to strict guidelines in the National Electric Code and with building codes.
In construction, electricians will work with blueprints to install the electrical systems into the structures. These prints tell them where the wiring will go and where circuits, outlets, load centers, and panel boards will be located. In factories and offices, a type of wiring with a metal covering called conduit is used. This type of wiring holds up better to the factory and office conditions. In lighter construction, plastic covered wiring, known as romex, is allowed and preferred over conduit.
Maintance work varies greaty depending where the electrician is employed. Those who work with residential homes may have to add a new circuit breaker or replace an old fuse box, while those who work in industrial maintenance, may have to do work on a robot or repair motors and generators.
This work can be strenuous at times. They may have to stand for long periods of time on scaffolding or work in cramped positions. They are often at risk to falls, shocks, or cuts. Sometimes electricians have to travel about 100 miles away to get to a job site. Most of them work a standard 40-hour week, overtime may be required at times.
A high school degree is required to be an electrician. Most people learn though by completing a four to five year apprenticeship program. The typical large apprenticeship program provides at least 144 hours of class room instruction each year, and 8,000 hours of on-the-job training over the course of the apprenticeship. Those who do not enter a formal apprenticeship program can begin to learn the trade informally by working as helpers for experienced electricians.
Answer:
Hey mate,
Your answer is as follows:
Electricians work with electrical power. They install, test, and maintain wiring, lighting systems, and fixtures in homes and businesses.
Electricians work indoors and outdoors. They work in new construction and in existing buildings. Electricians should have a basic understanding of mathematics, including algebra, and good problem-solving skills. Experienced electricians can work with architects and help design electrical systems for new buildings. Electricians also work with alternative energy sources that turn wind or sunlight into electricity.
It takes commitment to gain the proper training to become an electrician. Electricians need to have a license to be able to work in most states. Most electricians earn their licenses by participating in an apprenticeship program. An apprenticeship is when a student is taught a trade with hands-on experience by a master. This program lasts about 4–5 years. In addition to working on projects during this time the apprentice must also take hundreds of hours of technical courses.
