480 Volt Equipment Wiring
Commercial and industrial facilities’ electrical systems are an entirely different territory from residential electrical wiring, using higher voltages and many more electrical devices. To safely connect overhead lighting, industrial equipment, and all essential appliances to electrical power, the building must supply an adequate amount without overloading any application.
In industrial plants, warehouses, and other such facilities, machinery typically requires 480 volt equipment wiring to receive the appropriate amount of electrical power. TriStar Electric specializes in 480 volt equipment wiring and other commercial electrical wiring services. If you need this service in Maryland, please contact us today.

480 Volt Equipment Wiring Applications
480 volt equipment wiring applies to multiple devices in multiple types of buildings. Schools, hospitals, restaurants, warehouses, and offices are just several examples; they are buildings that need enough voltage to power a sufficient number of devices. They can power three-phase load equipment, which requires powering through all three phases (also known as lines). Some examples include welders, trash compactors, heating elements, dock levelers, and warehouse overhead door motors. 480 volt wiring can also branch off into three-phase or single-phase lighting applications for commercial lighting using a lower voltage.
Understanding 480 Volt Wiring
Benefits of 480 Volt Wiring
480V equipment wiring is the standard in the United States for commercial buildings due to its sufficiency and efficiency. In other words, its higher electrical potential decreases the concern for a voltage drop when connecting more electrical devices; this voltage is sufficient to power multiple lights and machines close to each other.
In the meantime, a high voltage means a lower current, which means less power loss due to resistance. This inverse relationship alludes to Ohm’s Law, which is that electrical power equals voltage times current or volts times amps.
The lower current level and the ability to branch off into lower voltages does away with the need for extra construction, transformers, and other hardware, saving businesses money.
480V Three-Phase Wye
The 480V three-phase Wye configuration is the more popular wiring system between the two options, Wye and Delta. The Wye configuration forms a Y-shape connecting three power lines and a neutral wire, which carries the return current. Each line is 277V, which can power 277 commercial lighting and other applications.
480V Three-Phase Delta
The 480V three-phase Delta configuration is more common in older commercial buildings and is the less desirable option because there is no neutral wire, and the ground wire is 480V, which is less safe. Even so, TriStar Electric can discuss with you which configuration makes more sense.
