This is not recommended. The heater will operate at more than its given specified wattage. A 208 volt heater run off 220 volts will have an output increase by 11.87 percent. Similarly, a 220 volt heater can be run off of 208 but the wattage will be reduced by 10.61%. The calculations, using Ohms' Law, are shown below.
<><><>
Watts = volts x amps (W = V x I) and I = W / V so, if we take a 2000 watts heater designed to run on 208 volts, I = 2000 / 208 = 9.6 amps
Resistance = volts / amps (R = V / I) so the heater's resistance is 208 / 9.6 = 21.632 ohms
Amps = volts / resistance (I = V / R) so, running on 220 volts, I = 220 / 21.632 = 10.17 amps
W = 220 x 10.17 = 2237 watts, which is an increase of 2237/2000 = 11.87%.
<><><>
W = V x I and I = W / V so, if we take a 2000 watts heater designed to run on 220 volts, I = 2000 / 220 = 9.09 amps
R = V / I so the heater's resistance is 220 / 9.09 = 24.2 ohms
I = V / R so, running on 208 volts, I = 208 / 24.2 = 8.595 amps
W = 208 x 8.595 = 1787.76 watts, which is a decrease of ( 2000-1787.76 ) / 2000 = 10.61%.
What else can I help you with?
Can you run a 208 volt device on 240 volts?
Running a device designed for 208 volts on a 240-volt power supply can damage the device due to the higher voltage. It's important to match the voltage specifications of the device with the power supply to prevent any harm or malfunction. Using a transformer to step down the voltage from 240 volts to 208 volts would be a safer option.
What is the maximum volts that can be used on a 208 230 volt motor?
You should not go above 240 volts for that type of motor.
Will a 208 volt 3 phase equipment work on 240 volt 3 phase?
Yes but a 208 volt heater is intended to be delta connected so there are only three terminals. The three heating elements could be rewired to run in parallel off a 220 v single phase circuit, and the heater would then operate at 12% excessive power, which might shorten its life. <<>> No. The heater will operate over its given specified wattage. A 208 volt heater run off of 240 volt will have an output increase. Ohms law stated that current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit. A 240 volt heater can be run off of 208 but the wattage will be reduced. For example if the heater is 5000 watts at 208 volts, the current is I =W/E 5000/208 = 24 amps. The resistance of the heater is R = W/I (squared) =5000/24 x 24 (576) = 8.68 ohms. Applying 240 volts on the same heater whose resistance is 8.68 ohms results in this new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/8.68 = 6636 watts. This is 1636 watts higher than the manufacturer's safety rating. W = watts, I = amperage, R= resistance in ohms and E = voltage.
Can you connect 208 volt equipment to 240 volts?
Electricity is NOT clean, meaning, it is not 208, 220, or even 240. It usually varies and spikes. The problem with the lights, is likely because it's cold in your shop. Florescent lights do not perform well in the cold. (or they might be getting old).However, you can test your "average" voltage coming in with your vom (volt omm meter, set on the 240 volt setting).However, the very existence of surge protectors should give you a clue about the consistency of electrical voltage.208 volt equipment on 240 voltsThe heater will operate over its given specified wattage.

What is a 208 circuit?
The 208 volt configuration is one phase of a three phase source at 240 volts, where the 208 volt circuit is connected between the center tap of one 240 volt phase (usually a grounded neutral, in the style of a standard 120/240 split phase system) and the high delta connection on either of the other two phases. 208 circuit would consist of two phases of a 208 volt wye system or could be all three phases. The voltage between conductors would be 208 volts. The voltage to ground from any phase would be 120 volts. A 240 volt delta system would give you a high leg to ground, somewhere around 190 volts and the other two would be 120 volts to ground.

How do you know if you have a 120 or a 240 volt baseboard heater?
To determine if you have a 120 or a 240 volt baseboard heater, check the electrical specifications on the heater itself, often found on a label or plate. Additionally, you can inspect the wiring: a 120 volt heater typically has a single wire and a ground, while a 240 volt heater usually has two hot wires and possibly a ground. If you're unsure, you can also use a multimeter to measure the voltage at the heater's terminal; a reading of around 120 volts indicates a 120 volt heater, while around 240 volts indicates a 240 volt heater. Always ensure safety precautions are taken when handling electrical components.
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.
Can i run a 240 volt water heater on 120 volt?
No. A water heater requires a 240 volt connection and cannot be re-wired to run on 120 volts. There isn't enough amperage in 120 volts to power the heating rods that are inside.
How many amps does a 240 volt 1500 watt electric base board heater use?
To calculate the amperage for a 240-volt, 1500-watt electric baseboard heater, you can use the formula: Amps = Watts / Volts. For this heater, it would be 1500 watts / 240 volts, which equals 6.25 amps. Therefore, the heater uses approximately 6.25 amps.
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.
What is the amp draw for a 3800 watt 240 volt water heater?
To calculate the amp draw for a 3800-watt water heater at 240 volts, use the formula: Amps = Watts / Volts. Thus, the amp draw would be 3800 watts / 240 volts, which equals approximately 15.83 amps. Therefore, the water heater draws about 16 amps.
How many volts can b drawn off a 240 volt breaker?
