What type of work can only be performed by licensed electrical workers?

Licensed electrical workers are specifically trained and authorized to perform electrical installations, repairs, or alterations due to the technical skills and knowledge required to ensure safety and compliance with relevant regulations and standards. This type of work involves handling electrical systems, which can be hazardous if not done correctly.

Ensuring that installations and repairs are carried out by qualified personnel helps to prevent accidents, fires, and other electrical hazards that could arise from improper handling. Licensed individuals are familiar with codes, safety measures, and best practices essential for maintaining electrical systems safely and effectively.

Other options, such as retail electrical sales, electrical product manufacturing, and electrical customer service, do not require specialized knowledge or licensing related to direct electrical work. These roles may involve dealing with electrical products but do not encompass the hands-on electrical work that necessitates a license.
