277 Volt Lighting and Wiring Services in Jessup

277 Volt Lighting and Wiring Services in Jessup tristar electric

If your commercial building needs 277 volt lighting and wiring services in Maryland, TriStar Electric is ready to help!

The United States and other countries have standard commercial and residential electrical system voltages. This standardization makes it easier for electricians and electronics makers to create devices that fit together safely. In the U.S., you will find different common voltages, such as 120V, 240V, 277V, 280V, and 480V. Each voltage type applies more commonly to one application or another. In the case of 277 volt wiring, it is commercial lighting. If your commercial building needs 277 volt lighting and wiring services in Maryland, TriStar Electric is ready to help!

How 277 Voltage Works

Voltage is electrical potential, the force that will push the electrons through the wiring. It is also known mathematically as current times resistance (V=IR.) Each electrical line has a specific voltage; in commercial applications, you will often see 277V for lighting.

277V lighting is a single-phase power system that connects to a 480/277V three-phase four-wire electrical system. Each of the three live wires used in a three-phase system is 277V, adding up to 480V because of the angles at which the wires relate to each other. A single-phase 277V wire may offshoot from the three-phase system to power multiple lights within a commercial space.

277 Volt Lighting and Wiring Applications

277 volt lighting can apply to any commercial lighting your building needs. It can apply to interior and exterior lighting alike in any industry, including education, manufacturing, healthcare, retail, and many more. Creating the ideal lighting conditions involves much more than installing a light bulb; experienced electricians must apply the most efficient wiring system possible, connecting the lighting outlets with the building’s external power source.
