120 208 3 phase 4 wire wiring diagram. It is important to note that with this type of wiring there are multiple phases in place each of which will get its own color wire to make it clear what it is for those working on it. Similar to the Three Phase Three Wire Delta discussed above but with a center-tap on one of the transformer winding to create neutral for 120 volt single-phase loads. 3 Phase 208v Motor Wiring Diagram wiring diagram is a simplified okay pictorial representation of an electrical circuitIt shows the components of the circuit as simplified shapes and the gift and signal connections amongst the devices.
This is the most common four-wire three-phase delta service and is essentially a 240 volt three-phase three-wire delta service with one of the 240 volt transformer winding center tapped to provide two 120 Vac circuits which are 180 degrees out of phase with. A Split Phase Capacitor Start Electric Motor may be defined as a form of split-phase motor having a capacitor connected in series with the auxiliary winding. Neutral - Neutral.
The neutral wire serves as common return to all the three phases acting outward from N 1. The Y in 208Y120V refers to the neutral as the center of the Y shaped power source.

The neutral points in both alternator and the load are joined together. A 240 volt meter is used for 277480V service. That lets you get 120V between any phase leg and neutral and 208V between any two phase legs.
Phase 3 - Phase 3 wiring should be blue. I run into this way more than Id care to. 1 overhead primary line connects to 1 single phase transformer which has 2 hots and a neutral come from it.
The 4 Wire in 208V 3 Phase 4 Wire refers to the neutral as 4th wire. In the above diagram the alternator is connected to the load by three phase four wire system. There are many compelling reasons to use 3-phase power in your data center.
