An electrical contractor works in the construction industry in a vital role. In this career, your duties and responsibilities require you to plan, install, and repair wiring and electrical systems in a building or for an outdoor project. An electrical contractor must be able to read blueprints and diagrams to understand the layout of the wiring and breaker boxes for the project on which they are working. These individuals also have to be able to work with a team and communicate properly, since larger projects often require several electricians and electrical contractors to complete the project on time and within the required project guidelines.
