NettetLow-voltage or limited-energy systems present the same ignition hazards as those of 120 volts and greater. The concern is that arcing, even at a low-energy level, could cause ignition of an explosive material. It is common to think low-voltage and limited-energy systems are less dangerous than higher voltage systems. NettetBased on 4 documents. Limited energy electrical activity means installation, alteration, maintenance, replacement or repair of electrical wiring and electrical products that do not exceed 100 volt-amperes in Class 2 and Class 3 installations, or that do not exceed 300 volt-amperes for landscape low voltage lighting systems that are cord ...
