When working with electricity, safety begins with understanding voltage levels. But what is considered high voltage? In general, electrical systems are categorized into low, medium, and high voltage depending on the application. High voltage typically refers to electricity above 1,000 volts AC or 1,500 volts DC, commonly used in power transmission, industrial equipment, and large-scale construction projects.

Recognizing high voltage is critical for preventing hazards such as electric shocks, equipment damage, or fire risks. This is why safety training is essential. A construction training course not only explains electrical standards but also teaches practical safety measures, proper tool handling, and protective techniques when working with high-voltage systems.

For professionals in the construction and electrical industries, knowing the difference between standard wiring and high-voltage applications can mean the difference between safe operations and costly mistakes. Whether you’re pursuing a career in construction or looking to upgrade your skills, combining theoretical knowledge with hands-on learning through a construction training course is the smartest way to stay safe and job-ready.
