Can I use 240V breaker for 208V?
Yes, because there’s little difference between a 3-phase panel and a split-phase panel of the same corner-neutral voltage. Apocryphally, 208V 3-phase found in Manhattan and 240V split-phase found in the rest of North America.
Is 208 and 240 volt the same?
“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.
Can 220V equipment run on 208V?
Most devices designed for 220 will run on 208 and in shops all over the place this is commonly done. Purely resistive components (like heaters) will run at a slightly lower power. So, your machine will work, but will take longer to come up to temperature.
Will 208V work with 220V?
RE: Can 208V 3 phase run 220V 3 phase machine
It will run, but not at the nameplate horsepower. If you try to draw rated torque/power from the motor it will probably eventually overload.
Can you get 208V from a 120V panel?
Therefore, if you put 120V in, you will get 120V out, 208V in gets you 208V out, 240V in gets you 240V out, etc. When you run 120/208V single phase power into an isolation transformer, the two individual hot conductors of 120V are combined into one 208V waveform.
How can I get 208 volts?
The formula is volts times the square root of 3, which happens to be rounded off to 1.732. For 2 lines each carrying 120 volts, the calculation for this is 120 volts times 1.732, and the result is rounded up to 208 volts. That’s why we call it a 208 volt three-phase circuit, or a 208 volt 3 phase line.
Can I use a 230 volt motor on 208?
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.
What size breaker do I need for a 208 230?
As for the 208/230 wiring…. the breaker will be a double pole with handle tie. It will be one breaker rated 50 amps not two individual breakers.
Can you run a 208 volt motor on 240 volts?
A 240 volt motor on 208 volts will run a little slower.
Does 208 single phase need neutral?
If your system only requires three phase operation or single phase 208, a neutral is not required. IF you did need a neutral then you would DERIVE it at your secondary of your service transformer.
