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.

What else can I help you with?
What are the specific electrical requirements for a 208/230 volt single phase appliance?
A 208/230 volt single phase appliance requires a dedicated electrical circuit with a voltage of 208 to 230 volts and a single phase power supply. The appliance should be connected to a properly rated outlet or wiring to ensure safe and efficient operation.
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.
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.
Can you take a 120 volt ballast and use it in a 277 volt light?
Yes, if there is a 208 volt connection on the multi tap ballast. One side of the 208 to the common terminal and the other side of the 208 supply to the 208 volt lead. 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.

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.
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.
What happens when 240 volt equipment is plugged into a 208 volt source?
It should be ok
Will a 208 volt rated appliance work on a 240 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.

Will 120 - 277 volt electronic fluorescent ballasts work on 208 volts?
NO! a 120-277 electronic ballast requires one "hot" wire and a neutral from either a 110V or 277V supply. If you supply it with two "hot" wires from a 208 V supply, it will instantly burn up.Yes. A ballast with a specification range of 120 volt to 277 volt will work on 208 volt. These ballast use intelligent voltage sensing technology and it does not matter if the source is a hot and neutral or two (2) hots. Don't believe it? Call a ballast manufacturer instead of giving incorrect answers.
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.
How do you switch the voltage requirement for a cooktop from 208 volts to 110volts?
You don't. The cook top was designed to operate on 208 volts. This is the voltage needed to get the elements up to their rated wattage to do the cooking. Higher wattage appliances do not operate on the lower voltage because of the size of the wire that is needed to feed the appliance.
