Electrical surge protection in an industrial setting has significant differences from residential, retail, and typical office settings – it is quite literally “no place like home.”
To begin with, the electrical service is different than it would be at home. Residential and non-industrial settings most often make use of single-phase power service at 120 or 240 volts. Electric service in commercial buildings is usually 120/208 volt three-phase power; in larger facilities service may go up to 277/480 volts. In contrast, industrial sectors like critical infrastructure, gas and oil facilities, factories, chemical plants, food processing plants and mining operations have much larger power requirements. In these settings, three-phase power with nominal service voltages of 240, 480 and 600.
