Three Phase Four Wire Wye 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.Wiring Diagrams Bay City Metering NYC
(120 208V or 277 480V) Meter rated 120 or 277 volt using line to ground voltage. If 240 416 service (uncommon), meter rated 240 volt, 240 and 277 volt wye meters are applicable to either 240 416 or 277 480 volt wye service, 240 volt meters have 240V nameplates and are calibrated at 240V.3 Phase Power Neil Orme
Wye Configuration Three Phase 120 208 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.Model 208 WYE 120 208 WYE Type 1 Utiliguard

Figure 1 represents 120 208V wye, which is delivered with four wires composed of one wire for each voltage and a neutral. Each of the three voltages are 120 degrees apart and have a common connection to ground and neutral (which are at the same potential) represented by the dot in the middle.Reverse wire Transfrmer 480v delta to 120 208 wye ...
Reverse wire Transfrmer 480v delta to 120 208 wye So where I really earn my money is what do I do with the XO on the 208 side. I got a Grd off the 208 side and my Grd on my 480 going in the pipe.208V Single Phase and 208V 3 Phase • OEM Panels
208V 3 Phase power also goes by the names 208V 3 Phase 4 Wire and 208Y 120V. These are technically more accurate because they refer to the neutral. The “4 Wire” in 208V 3 Phase 4 Wire refers to the neutral as 4th wire.
