Motors are rated for 10% over or under the nameplate voltage listed on the motor. This is a NEMA requirement. So, a 230 volt motor can operate as low as 207 volts. When a motor is rated at 208/230 volts this means the motor will operate at the 208 volt rating, not 10% under the 208 volt rating.
Can I use a 230 volt motor on 208?
On motors larger than 10 HP the 200-volt motor is general- ly the best choice; but in many situations 230-volt motors are frequently and successfully applied on the 208-volt systems.
Is 208V the same as 230V?
In North America, 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.
Can you run a 240V motor on 208V?
A 240V motor will run fine on lower voltage as long as there is a light work load. You can run a 460V motor on 240V but with very little available torque and no overheating under no load.
Will a 220V motor run on 208V?
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.
Is 208 and 240 the same?
The difference between 208V three phase, and 240V single phase, is how the voltage is derived. 240V single phase is obtained by taking a single leg of three-phase power. 208V three phase is obtained by taking two legs of three-phase power.
Is 208V always 3 phase?
208 volts is Line-to-Line Voltage. This three Phase voltage is frequently used in small businesses. … The power is brought is as 208 volts 3 Phase and then the Line-to-Neutral Voltage will be 120 Volts. Each of the three Line-to-Neutral line will go to a part of the plant.
What is the difference between 208V and 220V?
208V is a line to line voltage of a 208/120Y system. 220V is a line to ground voltage of a 380/220Y system. 240V is the line to ground of a 415/240Y system.
What’s the difference between 220V and 230V?
220/230/240 are the same thing, really
US single phase line-to-line mains voltage is interchangeably referred to as 220V, 230V, and 240V. … (There are several three-phase systems in the US, with various voltages involved, but they are beyond the scope of this answer.)
Can you get 240V from 120 208V?
4 Answers. It isn’t. 120/240V is a 240V single phase supply, center tapped to produce a “split phase” with 120V between either side to neutral, and 240V between the two hot lines. 120/208V is two phases from a three-phase supply.
Can you get 220V from a 120 208 panel?
220-volts and 240-volts are effectively the same thing. 220-volts nor 240-volts can be derived from a 208Y/120 volt system.
Does 208 have a neutral?
Although phase balanced can occur, there is no neutral connection on 208 circuits, therefore no physical way for current to flow. The only purpose for a neutral would be for 120 convenience outlets.
