WYE WIRING DIAGRAMS 208 120 VOLT
Electrical Service Types and Voltages – Continental
The most common commercial building electric service in North America is 120/208 volt wye, which is used to power 120 volt plug loads, lighting, and smaller HVAC systems. In larger facilities the voltage is 277/480 volt and used to power single phase 277 volt lighting and larger HVAC loads. In western Canada 347/600V is common.[PDF]

3 Phase Power
Three-phase service is commonly provided to large buildings and facilities to power both three-phase loads and 120 volt single-phase loads. Wye is the most common configuration provided by the electric utility. Figure 1 is a 120/208V Wye system in North America, which is delivered with four wires composed of one wire for each voltage, plus a

Engineering Tools. Vs. 3 Phase WYE (Y) A 3 Phase-Wye connected system consists of three hot lines, or phases, commonly referred to as X, Y, Z, a neutral, and a ground wire for a total of five wires in a power distribution cable. In North America the most common 3 Phase-Y voltages are either 120/208 VAC or 277/480 VAC, while internationally the

120/208V wye primary 480V delta secondary bonding question
Oct 28, 2014Hello all, I'm working on a job that has a new 120/208V 4-wire wye service. From that new new service (which is a 1000A fused switch), it feeds a 300 Kva transformer. The transformer is a 120/208V wye primary, and 480V delta secondary. From the 300 Kva transformer, it feeds a

How to Wire a High & Low Voltage Three-Phase Motor
A three-phase motor is more efficient than a single-phase motor because of the peculiarities of alternating current (AC). Wire a three-phase motor in either a wye configuration or a delta configuration, in high or low voltage, using a nine-lead set-up.
