277 Volt Lighting and Wiring

The United States and other countries have standard voltages for commercial and residential electrical systems. 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, and 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 provide power for 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.

Consider an Upgrade to LED Lighting

In new construction commercial buildings, LED lights are the default choice for interior and exterior lighting. LED lights are by far the most efficient choice compared to any older type of lighting like HID, fluorescent, incandescent, mercury vapor, etc. Benefits you can gain with commercial LED lights include the following:

  • Low cost: LED lights use significantly less wattage, which is what the energy company charges you for.
  • Long lifespan: Improperly manufactured LEDs turn purple, but standard LED bulbs can last for years.
  • Brilliant light: LEDs can take on the appealing look of incandescent light. You can trust LED bulbs to provide consistent, bright lighting for indoor and outdoor spaces.

At TriStar Electric, we highly recommend considering an upgrade to LED lighting.
