Encyclopedically about NEC
The National Electrical Code (NEC), or NFPA 70, is a regionally adoptable standard for the safe installation of electrical wiring and equipment in the United States. It is part of the National Fire Codes series published by the National Fire Protection Association (NFPA), a private trade association. Despite the use of the term "national", it is not a federal law. It is typically adopted by states and municipalities in an effort to standardize their enforcement of safe electrical practices. In some cases, the NEC is amended, altered and may even be rejected in lieu of regional regulations as voted on by local governing bodies.
The "authority having jurisdiction" inspects for compliance with these minimum standards.
Industrial work for electric engineers
Electrical contractors employ workers in many capacities, determined by their level of training and experience. Some common jobs include:
Apprentice Electrician ? Receives on-the-job training and classroom instruction from licensed journeymen or master electricians about how to install, modify, repair, and maintain power and lighting systems. Most apprentice programs last 3 to 5 years and apprentices earn wages during this training period.
Journeyman Electrician ? Installs, modifies, repairs, and maintains power and lighting systems. Reads blueprints, terminates cable, and installs and troubleshoots control wiring from drawings. Has completed the apprentice program and holds a journeyman's license (according to state requirements) and supervises apprentices.
Estimator ? Calculates a project's duration and cost, including materials, overhead, and labor. This estimate is often submitted as a bid on a project and serves as a scheduling and budget guideline as the project proceeds.
Project Supervisor ? Oversees workforce to encourage safe and high-quality installations. Monitors progress to meet project deadlines. Submits required reports and forms.
Electricity and safety
Occupation electrician is very often seen as a profession in which extremely common ones are physical injury. This is related primarily to the fact that when working with electricity, even the smallest mistake can cause severe short circuit, which would be harmful to human health. Usually created a power failure is unexpected and electrician seeking a solution to the problem moves groping. Therefore, for such a mistake it is very easy and you can tell that no theoretical knowledge is not able to prepare the employee to perfect the profession, because of some random events can not be predicted.
