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.
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. In North America, the utility companies are required to deliver split phase 240VAC for residential use.
In short, just because a 208v motor may be designed to run on 230v or 240v systems by using two power legs from the utility source, that doesn’t mean that it will provide the same output efficiency. You will see differences in performance if you try to use 208v when 240v is typically required.
Even though the system voltage of 3 phase 208 is within the -10% rating of the three phase 230 v motor, the 208 is allowed to vary to -10% or 187 volts — and the motor will not work at that level.
If you have 220 volts and 3 phase power3 phase powerThree-phase power works by the voltage and currents being 120 degrees out of phase on the three wires. As an AC system it allows the voltages to be easily stepped up using transformers to high voltage for transmission, and back down for distribution, giving high efficiency.https://en.wikipedia.org › wiki › Three-phase_electric_powerThree-phase electric power – Wikipedia available, the kiln will come with a 3-wire powerblock for the 3 hot wires that give the 3 phase. Between each hot wire, 220 volts can be measured. There is no need for a neutral wire to come to the kiln in this case, just an earth ground wire in addition to the 3 hot wires.

Can 220V be 3 phase?
If you have 220 volts and 3 phase power available, the kiln will come with a 3-wire powerblock for the 3 hot wires that give the 3 phase. Between each hot wire, 220 volts can be measured. There is no need for a neutral wire to come to the kiln in this case, just an earth ground wire in addition to the 3 hot wires.

Is 208 volts the same as 230 volts?
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. The motors that are truly intended for 208 volts are nameplated for 200 volts.
What does 208V mean?
Sep 26, 2003. 120/208VAC means that power distribution is 3 phase with neutral connection (Y System). 120V represents voltage of each phase to neutral point and 208V represents voltage between any two phases. For balance systems, line to neutral voltage is line to line voltage divided by 1.73 (Sq.

Is 208 and 240 volt 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.
Can 230v equipment run on 208V?

Can you run a 3 phase 220v motor on 208v 3 phase? – Eng-Tips Forums
If you had 50Hz 3-phase I would say yes because 208V is just about within the normal tolerance on the supply voltage. I suspect from the 208V that you are in the 60Hz world, likely North America, and in that case the answer is no. The 220V and 380V are standard European 50Hz voltages for delta or star connected windings respectively.
Running 208v motor on 220v service | The Hobby-Machinist
Jun 2, 2017. #2. That one is a tough call. Most newer motors will run 208-240 just fine. 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. I would wire it up and put an amp probe on it, if the current draw is within reason, you should be fine.

What’s the Difference Between 208v and 240v? – HVAC School
208/230v motors also have a harder time starting up, and they may produce a problematic voltage drop more often when connected to 208v. Voltage drop usually isn’t an issue for split-phase 240v systems. However, on 208v, the motors start with a lower voltage. Therefore, the same amount of drop will have a greater effect on the system.
Can You Run a 208 Volt Motor on 240 Volts? – otonomic.com
The usual voltage is 240v. But homes may have varied options like 208v, 220v. Most 208v runs in 240v equipment but be sure with the template manual. Both 208v and 240v differ in phase power. So the question comes here: can you run a 240v motor on 208v. Since One has a single, the other has three phases. So the delivery of the power load differs.
