An electrical contractor is a business or individual specializing in electrical construction work. They handle the design, installation, and maintenance of electrical systems in various types of buildings, including residential, commercial, and industrial structures. Unlike electricians, who are individual tradespeople, electrical contractors operate as businesses or companies that employ electricians. These contractors typically hold licenses and insurance to ensure safe and proper operation while protecting employees and property owners from liability.Here are some common roles within the field:
1. Apprentice Electrician: Receives on-the-job training and classroom instruction from licensed journeymen or master electricians. They learn how to install, modify, repair, and maintain power and lighting systems during their 3 to 5 years of apprenticeship.
2. Journeyman Electrician: Installs, modifies, repairs, and maintains power and lighting systems. They read blueprints, terminate cables, and troubleshoot control wiring. Journeyman electricians supervise apprentices and hold a journeyman’s license.
3. Estimator: Calculates project duration and cost, including materials, overhead, and labor. Their estimates serve as project bids and provide scheduling and budget guidelines.
