But as it turns out both the 120 volt and 240 volt alternatives can be beneficial depending on your needs and appliances.
120 208 voltage explained.
In larger facilities the voltage is 277 480 volt and used to power single phase 277 volt lighting and larger hvac loads.
When the lines were installed the plant was divided into roughly 3 equal area from a power usage standpoint with one line going to each area.
In western canada 347 600v is common.
That is there is a 120 degree phase shift between each live wire s waveform 360 degrees being one full cycle.
Some analysis would need to be done to see if a particular item would work.
Simply put on some combinations of ups model bypass switch type and input voltage there exists the potential for an incompatibility.
Each leg phase provides power phase voltage at a unique angle phase angle to the center neutral.
Appliances and equipment rated for 120 208 volts but not 120 240 volts may generally not be used on a 120 240 volt system or on a system that measures 110 220 volts.
Each of the three line to neutral line will go to a part of the plant.
The power is brought is as 208 volts 3 phase and then the line to neutral voltage will be 120 volts.
120 208v single phase power.
Why are they used what s the purpose behind them and where do the numbers come from.
208v 3 phase power also goes by the names 208v 3 phase 4 wire and 208y 120v.
Appliances and equipment rated for 120 240 volts may be used on a system that measures 110 220 volts.
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.
208v 3 phase power has 3 electrical legs phases evenly spaced in a circle 360 degrees 3 phases 120 degrees around a center neutral.
120 208v single phase is derived from 208v three phase power.
What is the difference between all of these different voltages.
A 240 volt outlet on the other hand is larger with room for three individual plugs or four plugs of varying size.
