Check for the voltage tolerances specified on the equipment. If the tolerance cover the 220V range, it is Ok to proceed by plugging into 220V outlet. This is normally taken care for a 208V equipment to be used with 220V supplied, except that the life span will be affected. From Safety point of view, it is not advisable to do so if the tolerance is not found.

How do you wire a 4 wire 3 phase to make 110?
In North America the only three phase supply that 120 volts can be obtained from is a 208 volt system. 120/208 is a common voltage connection that is used in many apartment and commercial buildings. The 208 voltage can be used in lieu of 220 volt appliance equipment and the line to neutral voltage results in 120 volts. It is obtained by the following formula 208/1.73 = 120 volts. For apartment distribution panels, two of the three legs are used along with the common neutral. The main distribution is kept in reasonable balance by alternating different apartments on different legs of the three phase distribution service.
What is the difference between 208 volt and 220 volt power?
The main difference between the two voltages is that the 208 volts is a three phase voltage and 220 volts in North America is a single phase voltage. If you operate a 220 volt motor on 208 volts the current will be 5% higher that the motor's nameplate rating. If the load is resistive and you operate a 220 volt baseboard heater on 208 volts the true heater wattage will not be reached because of Ohm's law. Current is directly proportional to the applied voltage and inversely proportional to the resistance in the circuit. The following statement is not true as many motors will have the two voltages on the motor's nameplate. You can operate a 208 volt motor or appliance on 240 volt, but that will decrease life expectancy by 50%.
Do you need a step down transformer to run a 208 volt steam table on 240 volt feed?
Yes a transformer should be used. The steam table needs its correct voltage otherwise on 240 volts it will operate over its given specified nameplate wattage. A 208 volt heating element run off of 240 volt will have an output increase by 75 percent.
Can you plug 230 volt equipment into 208 powered outlet?
It depends on the equipment. The nameplate of the appliance should have the appropriate voltage tolerances and frequency requirement. In North America, most appliances will be designed for 60 Hz use. Higher voltage residential appliances are typically rated at 230 VAC. The typical household voltage supplied by the utility is between 220 - 250 VAC (between phase), and 110 - 125 VAC (phase to ground) . In commercial and multi-family units, it is very common to have 120/208 VAC instead (beyond the scope of this question). Therefore, most ranges, water heaters, air conditioners, heaters, and dryers are designed to operate at 208 VAC as well. You should read the nameplate of the appliance, read the owners manual, and / or consult a licensed electrician if you are still unsure. C. P., Master Electrician
What is the breaker size for a 10 KVA electric heater?
What size breakers are needed for a 30kva transformer 208 volt feed 600 volt out put
Does a 208 volt outlet need a neutral?
No a 208 volt outlet does not need a neutral. 208 volts is the line voltage between any two legs of a three phase 208 volt system.
You have three phase power and you have a motor that needs 208 volts can you conectt it to the line carries 208 only?
If your appliance or motor is asking for 208 volt, it usually means that it also wants 3 phase. If you measure the voltage between the hots on a 3 phase feed, you will find that it is somewhere around 208v. As long as you connect it to the 2 or 3 hots that you measured, then you will be fine. Make sure you ground, and no neutral should be present.
Do all electric ovens cooktops ranges and clothes dryers operate on 208v as well as 240v?
No, use only the voltage for the appliance that your utility system is supplying to your residence. If your system is 208 volts use 208 volt appliances. Likewise if the utility system is 240 volts use only 240 volt appliances. 208 appliances on 240 will overheat the appliances and 240 appliances on 208 will not produce the wattages that the manufacturer recommends for cooking and drying.
Why won't a 230-460 volt motor work on a 120-208 volt circuit?
Because its designed to operate at 230-460, not 120-208.
What happens when 240 volt equipment is plugged into a 208 volt source?
It should be ok
Can you connect a 277V ballast to 208V line service?
No. A 277 volt ballast needs the correct voltage to operate. The 277 voltage is derived from the star point voltage of a 480 volt three phase system (277/480). The 208 voltage is a three phase line voltage whose star-point voltage is 120 volts (120/208).

Can you operate a 208 volt on 110 volt?
The United States is one of the only places in the world that uses 110 volts instead 220 volts. In order to operate 208 volts on a 110 volt electrical current, you will need a voltage converter.
Normal voltage house in the US?
The vast majority of homes are supplied with 120/240 volt or 110/208 volt.
How do you convert 208 volt amps to 480 volt amps?
Add another leg of 120 to a three pole breaker.
Will a 240 volt appliance work on a 208 volt feed?
No, there is over a 15% difference in voltage supplies. This means that the current supplied to the 208 volt equipment will also be 15% higher. Take a 4000 watt range. I = W/E 4000/240 = 16.6 amps. 4000/208 = 19.2 amps. A 240 volt appliance will run on 208 volts but as you can see from above equation the range elements will not get as hot at the lower voltage.To get a the answer you have to reckon with the resistance of the appliance. A 4000 watt appliance running on 208 volts takes 19.2 amps, so from Ohm's Law R = E/I, its resistance must be 208/19.2 = 10.83 ohms.Again using Ohm's Law I = E/R, the current that resistance takes at 240 volts must be 240/10.83 = 22.16 amps. So the power drawn will be 22.16 x 240 = 5,318 watts.If it is a cooking ring or a heater, that power may cause the temperature to rise so much that its element could glow dangerously white hot and, at best, it may then melt or burn away with lots of smoke and heat. If it was some other appliance it may well overheat so much that it simply catches on fire. So the real risk here is that, if left unattended, the higher voltage could cause a house fire.As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.Before you do any work yourself,on electrical circuits, equipment or appliances,always use a test meter to ensure the circuit is, in fact, de-energized.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.
