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?
Can 210 volt appliances be plugged into normal house plug?
110 Volt is the nominal standard used in homes. Appliances are rated at 120 volts as a safety measure, as the voltage can fluctuate between 110v and 115v. Appliances rated in this manner will require voltages higher than 120v in order to sustain damage. Might call it a safety net for appliances.
Can you run a 208 volt oven on 220?
Yes. This is the same standard. The terms 208 and 220 mean the same thing, much like household voltage is sometimes called 110 or 120.
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.
I have a electrical dryer 240 receptacle that reads 208 on voltmeter and the dryer display reads Pwr Failure and will not operate were did the other 30 volts go?
I am assuming that you have just moved into a new apartment building. Commercial building power systems are changing to 3 phase. The 3 phase voltages are 120/208. 240 volt equipment will run on 208 voltages but at a reduced wattage output. For example Watts = amps x volts. Say your dryer draws 20 amps x 240 volts = 4800 watts. Now at reduced voltage, 20 amps x 208 volts = 4160 watts. As you can see your dryer won't get as hot and will take longer to dry. Most apartments that come with appliances will be rated at 208 volts. See what your dryer manufacturer has to say about getting around the Power failure alarm or whether it can be bypassed to operate on the lower voltage. Other option is to sell the 240 volt dryer and buy a 208 volt dryer. at 208 volts it will not draw 20 amps either
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.
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.
Can a 208 volt hot water heater be used with 110 volt with a 20 amp fuse?
Yes, but by using 120 volts on the 208 volt element you will only be able to obtain 1/4 of the rated wattage from the element not 1/2 like it seems you should.
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.
