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.
Will a 230V single phase motor run on 208V?
A 208V rated motor should not be run on 240V, nor should a 230V rated motor be run on 208V, motors rated 115/200-230V or 115/208-230V are fine either way, older 3Ø motors rated 220/440V will be fine on either a 208 or 240volt supply when connected for lower voltage.
Is 208 and 230 volt the same?
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. The motors that are truly intended for 208 volts are nameplated for 200 volts. … Note that the 230 volt will have a wild leg (230 volts to neutral) on that particular leg.
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.
Can 220v equipment 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.
How can you tell 208V from 240V?
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. Click to see full answer.
Is 208 and 240 volt the same?
2) The nominal line-line voltage is 208V, and this isn’t a nominal utilization voltage (sometimes you will see loads designed to connect to nominal 240V supplies called 230V or 220V loads; these are utilization voltages, and essentially mean the same thing as ‘240V’. 208V is really a different lower voltage.)
What is the difference between 208V 220V and 240V?
They require two legs of power from the power utility, whereas 240v motors and appliances only use one. You will commonly see 208v present in three-phase buildings when “single-phase” equipment (like an A/C condenser) is wired to two legs of three-phase wye power.
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.
