A 240 volt motor on 208 volts will run a little slower. Running slower decreases the counter EMF (back emf?) and the current will go up. However, a motor running slower does less work so the current doesn’t go up as much as you might expect. For example, a fan running slower moves less air and draws less current.
The wrinkle with three phase power comes when you would like to power 240v devices (e.g. a well pump, stove, dryer). If the device’s nameplate states that it can run at 208v (in addition to say 220v or 240v), you are fine. Sometimes the nameplate will state 208-240v as acceptable voltage ranges.
Thereof, Is 208 volts the same as 240 volts?
“220” and “240” are the same thing. “220” is what the unqualified use to describe 240 volt circuits. 208 can only be obtained from a 3-phase wye system. 240 volts can be obtained from either a 120/240 residential system or a 240 volt 3-phase delta system.
Also to know is, Is 208v the same as 240v? 208V is *not* the same as 240V. 208V is the voltage between phases of a 3-phase “Y” circuit that is 120V from neutral to any hot. 480V is the voltage between phases of a 3-phase “Y” circuit that’s 277V from hot to neutral.
Subsequently, question is, What is 208 volts used for? 208 volt is one of several standard electric voltages that come from commercial transformer configurations. 208 volt is used in commercial buildings and available as: -208 volt 3-phase with 3 Hot wires plus a ground. -208 volt single phase with two Hot wires plus a ground.
Also, Can I run a 208v motor on 240v?
2) Yes, the 10% gets you some added range of voltage. BUT, there is also 10% on the supplied mains voltage. So, a 240V nominal mains circuit would be within spec at just below 264V. … But typically a motor DESIGNED to only run on 208V would be MARKED as “200V”, what’s called the “Utilization Voltage”.
Is 208v the same as 220v?
In NA, the terms 220V, 230V, and 240V all refer to the same system voltage level. However, 208V refers to a different system voltage level. … With electrical loads, the voltage will drop, hence the common reference to voltages below 120 and 240, such as 110, 115, 220, and 230.
What is the difference between 208 and 220?
“220” is what the unqualified use to describe 240 volt circuits. 208 can only be obtained from a 3-phase wye system. 240 volts can be obtained from either a 120/240 residential system or a 240 volt 3-phase delta system.
Is 200v the same as 208v?
Senior Member. 200 volts is the rated voltage of a motor intended for use on 208V, just like 230V being for use on 240V, and so on….
Can you use a 208v on 240v?
Only proper way to run a 208V item w/ a 240V supply is to use a buck/boost transformer to buck the voltage down, this will be a lot cheaper then changing elements as some of the ones used in food service equipment can be costly. One should only operate equipment at the voltage it was intended to be run at.
Can a 240v dryer run on 208v?
Most electric dryers are rated at 240 volt. … Any appliance that is rated for 240 volts can also be used on a 220V or 208V outlet.
Can you run 240v on 208v?
The wrinkle with three phase power comes when you would like to power 240v devices (e.g. a well pump, stove, dryer). If the device’s nameplate states that it can run at 208v (in addition to say 220v or 240v), you are fine. Sometimes the nameplate will state 208-240v as acceptable voltage ranges.
Can you run a 208 volt motor on 240 volts?
Nominal system voltages are 120, 208, & 240. 120/208 or 120/240. 230 volt motors are designed to run on 240. 208/230 volt motors are designed for use with 208 or 240 volt supplies.
Whats the difference between 208v and 240v?
The difference is that the two ungrounded lines of the 208V system are not exactly opposite in phase, like the two lines of the 240V system are. Instead, they are 120 degrees out of phase.
Can 220v equipment run on 208v?
Most cooking appliances are rated at 240 volt. The nominal voltage is 240 volt, but homes may have 208V, 220V, or 240V power supply. Any appliance that is rated for 240 volts and can also be used on a 220V or 208V outlet.
Is 220v and 208v the same?

Can you run 208v on 220v?
220-230-240 (depends on utility) is the standard nominal 1-phase voltage across both legs of the line (120 nominal being the voltage from either leg to neutral). Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done.
