Can You Run A 208 Volt Motor On 240 Volts Best Info
Can You Run A 208 Volt Motor On 240 Volts. To begin with, disconnect the 240 vac power and apply an ohmmeter to the same motor terminals to which you had applied the 240vac power. Running slower decreases the counter emf (back emf?) and the current will go up. A 200 volt motor was originally manufactured to run on a 208 volt systems. 240 volts is from a single phase system like you have in your house. Roy is correct, you can run a ac/dc welder on 208, but the amperage setting will have to be set higher than it would be at 240 volts. Many motors are rated at 460 and 230 simpy because there is an assumed voltage drop in the 480 or 240 feeders. It may work on 240 volt single phase but the imporat part is see the nameplate to verify it and that heater do have two diffrent connection. Running slower decreases the counter emf (back emf?) and the current will go up. If this is a home i would not be concerned. However, a motor running slower does less work so the current doesn't go up as much as you might expect. That one is a tough call. 230 volt motors are designed to run on 240. If your phase converter is actually putting out 220v you should be fine, but i suspect if your power is anything like mine, you will be closer to 240v. Most modern devices can support this, but you must check the nameplate of each device to be powered. A 240 volt motor on 208 volts will run a little slower.
Can You Run A 208 Volt Motor On 240 Volts
When this approach is taken, the motor manufacturer is essentially saying that this motor can be successfully operated on voltages as low as 208 minus 10% or 187 volts. I trust that it happens all the time, it's the 'no problem' thing i am suspect of. 30 amp breaker is fine 240 volt heater on 208 will just be a little slower. The load torque demand is the same at the same speed, so the current will adjust itself at 115% of what was planned to be pulled by the load originally. 460 volt motors are designed to run on 480 208/230 volt motors are designed for use with 208 or 240 volt supplies. That's the +10% nema requires equipment to be able to withstand. If the device’s nameplate states that it can run at 208v (in addition to say 220v or 240v), you are fine. Another possibility would be to buy a 16/32 or 12/24v transformer to buck your 240v single phase down by 24 or 32 volts, for this to work you need to buck both 120 lines equally. It may work on 240 volt single phase but the imporat part is see the nameplate to verify it and that heater do have two diffrent connection. The highest voltage you should put to a 208 volt motor is 228 volts. 220 volts would be at the upper end of the safe range while 240 volts would exceed it. Leave the third leg from the rpc alone, send it straight into the motor, as its voltage will drop under load anyways. As the op has pointed out, the coil is stamped with 208v while the motor nameplate is marked 200v. This has probably been covered before, if so, my apologies. A 240 volt motor on 208 volts will run a little slower.

In a nutshell, a church as 240 volts (measured) in the panel. This has probably been covered before, if so, my apologies. Running slower decreases the counter emf (back emf?) and the current will go up. A 240 volt motor on 208 volts will run a little slower. However, a motor running slower does less work so the current doesn’t go up as much as you might expect. They require two legs of power from the power utility, whereas 240v motors and appliances only use one.

Leave the third leg from the rpc alone, send it straight into the motor, as its voltage will drop under load anyways. The highest voltage you should put to a 208 volt motor is 228 volts. For example, a fan running slower moves less air and draws less current.
When this approach is taken, the motor manufacturer is essentially saying that this motor can be successfully operated on voltages as low as 208 minus 10% or 187 volts. No…208 and 277v are from three phase system. It may work on 240 volt single phase but the imporat part is see the nameplate to verify it and that heater do have two diffrent connection. Air make up and range hood motors are labeled 208. If it reads high ohms, either the windings of the motor are burnt open (throw the motor away) or the terminals you chose are not those used to power the motor. Can you run 240v on 208v. Many motors are rated at 460 and 230 simpy because there is an assumed voltage drop in the 480 or 240 feeders. Roy is correct, you can run a ac/dc welder on 208, but the amperage setting will have to be set higher than it would be at 240 volts. Torque is current x flux.

Can you run a 208 volt motor on 240 volts? 30 amp breaker is fine 240 volt heater on 208 will just be a little slower. You still should not exceed the rated hp, but it will take less current to get there when the input voltage is higher. 240 volts is from a single phase system like you have in your house. That's the +10% nema requires equipment to be able to withstand. Flux is reduced to 208/240=200/230=86.7%. Ec says it's no problem, happens all the time. Nominal system voltages are 120, 208, & 240.

If you really look at most new energy efficient motors, you will see that they are rated to be used at 208v now, the motor mfgs know that 120/208v 3 phase is the most common commercial voltage.
