Licensed Electrician or Technician is expected to have strong knowledge in Electrical Science concepts. Normally electricians will be carrying out works related to installation of new electrical components, maintaining or repairing the electrical infrastructure. For carrying out these duties NEC code books, thumb rules and other calculation resources will be referred. But in-order to understand the work in depth knowledge in electrical basics is required. Electrical Basic Theory is tested in almost all the License exams for understanding the ability of the electrical knowledge of the candidate.
