[QUOTE="okierider, post: 3160250, member: 41708"] [SIZE=5][B]An Overview Of 277 Volt Electrical Systems[/B][/SIZE] Industrial and commercial power is delivered in 120/208-Volt and 277/480-Volt systems. Heating and ventilation systems are run at 480 volts while industrial scale lighting runs at 277 Volts. A 277/480-Volt system powers the industrial and commercial equipment at 480 volts while the 277 volt wiring powers the lights. Electrical discharge lighting is designed to run on 277-volt wiring. A three-phase, four-wire distribution system running at 277 volts is used for high voltage lighting like LED arrays and fluorescent lights. Electricians can run 277 volts off 480-Volt AC circuits. A 277/480V, three-phase system can provide single phase or three-phase power at 277 volts or 480 volts. Electrical distribution systems with 277-Volt wiring use step down transformers to provide either 240-Volt or 120-volt power as required. Residential AC circuits use power at 120 amps and 277 volts. Wiring of a 277/480-Volt system can supply both industrial and residential users. Using 277-Volt wiring permits more lights to be powered by a single branch circuit. This reduces the amount of high voltage wiring that must be installed to connect banks of LED or fluorescent lights, or appliances. [/QUOTE]
