For many years after Edison introduced the light bulb, consumers refused to buy a lamp that could use both electricity and gas. Most people thought electricity in the home was a passing craze, and they wanted to be ready for the return of gaslight. 

Of course, civilization today is dependent on electricity and the men and women who splice the lines and install the switches that allow energy to flow. 

Electricians' jobs are as diverse as the uses for electricity themselves. Some work for electrical contractors who focus on new building. Others work for government agencies such as public utilities and highway departments. Others work in assembly, industrial, and manufacturing plants, and many work for themselves. 

Electricians must be extremely cautious wherever they operate. They also need good colour vision to connect color-coded cables correctly. They must be able to read blueprints and, most importantly, do their work in accordance with national, state, and municipal building codes. 

Electricity is no longer a passing craze; it already powers the entire world. That is why, regardless of where they desire to work, there will always be opportunities for trained electricians.
