Electrical codes are the rules and regulations that have to be followed while performing electrical works of any sort. Electric codes are devised by many national agencies and from these, The NEC or The National Electric Code, are the prime standard accepted throughout the world. These are a written set of rules and regulations which are published in a bound book with 1,000 pages. The NEC is the most important document in the electrical industry and is widely accepted throughout the world. The whole code undergoes revision every three years based on new technology and needs of the industry. Following are 5 reasons which states the need for construction professionals to have a thorough understanding of this code
Lays Down Building Requirements
The National Electrical Codes which are also known as NFPA 70, lays down the requirements for the electrical equipment installation and wiring to be followed in all buildings. The code addresses the installation of electrical equipment, conductors, and raceways in industrial and residential occupancies. The code should be followed not only during the construction of buildings, but also during the renovation phase.
Guidelines for Safety
The NEC is designed to ensure safety of the electrical workers and to maintain uniformity in the work carried out. These codes should be adopted so as to provide safety regulations for consumers, who are the occupants of the building.
Essential for Project Approval
The rules of the National Electrical Code states that you should obtain a work permit before starting off with the project. Following the completion of the project an electrical inspector should visit the work site to certify that all the works have been done in compliance with the standard rules and regulations.
The first inspection by the inspector which is called the rough inspection should be carried out before the insulation of the wiring is done. This will give the inspector a clear view of the entire wiring of the building. The second inspection which is the final inspection will be carried out after completion of the entire work. An approval for the electrical work by the inspector is necessary as it certifies that all work is carried out in accordance with the rules and codes. If the inspector finds out that the work is not in compliance with the NEC, then the whole electrical work will have to be re-done. Hence, it is very important for a construction professional to be aware of the NEC, to get an approval for the work done.
To Have a Detailed Knowledge of Rules
The National Electric Codes specify a set of rules to be followed while installing electrical machinery in each room. There are separate codes for bathrooms, bedrooms, kitchens, stairways, laundry, garage, and other rooms. You can get an idea about these codes from the NEC handbook, or else you can take the help of standard guides that interpret these codes in a simple manner.
Idea about Local Guidelines
A construction professional should consult the electrical inspector well before beginning the work, to have an idea about the specifications of the work to be done. This is essential because the local codes may sometimes show slight variation from the list of rules in the NEC. Hence you should have a thorough idea of the rules pertaining to your locality, in order to save time and money.
