What type of work might unlicensed electrical installers be restricted from performing?

Unlicensed electrical installers are often restricted from performing complex installations and modifications due to safety regulations and the need for specific expertise in electrical systems. These types of tasks typically require a deep understanding of electrical codes, standards, and potentially hazardous conditions that an unlicensed individual may not be adequately trained to handle. Complex installations can involve sophisticated equipment, multi-circuit systems, or large-scale modifications that could pose significant safety risks if not managed correctly. Therefore, strict regulations are in place to ensure that only those who have completed the necessary training and obtained appropriate licenses can undertake such work, thereby helping to protect public safety and ensure compliance with electrical codes.
