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.
What else can I help you with?
Is it possible to hook up a unit that is 208 volt single phase to a 240 volts 3 phase?
Any two legs of a three phase system are classed as single phase. If a 208 volt device is connected across two legs of a 240 volt system its current draw will be higher. It is not recommended to connect a 208 volt device to a 240 volt supply. Using a constant resistive load of 6000 watts for an example, the resistance of the unit at 208 volts has to be found. R = E (squared)/W = 7.21 ohms. Now using the formula to find amperage at this resistance I = E/R, 208/7.21 = 28.84 amp at 208 volts. If the 208 volt device is connected to a 240 volt supply the following condition happens. I = E/R, 240/7.21 = 33.29 amps. The device in now definitely overloaded and instead of its rated 6000 watts it is outputting W = A x V, 33.29 x 240 = 7989 watts almost 2000 watts more than the unit is rated at.Using a 240 volt rated device on 208 volts is more forgiving and is done quite often. Using the same 6000 watts on 240 volts the resistance is calculated to be R = E (squared)/W = 9.6 ohms. If the 240 volt device is connected to a 208 volt supply the following condition happens. I = E/R, 208/9.6 = 21.67 amps. To check this connection's wattage W = A x V, 21.67 x 208 = 4507 watts or about 1500 watts below its rated output at 240 volts.If the connected load is a constant wattage like a motor, the amperage and voltage will change to maintain the constant wattage. I = W/E. A motor rated at 6000 watts at 240 volts will draw 25 amps. A motor rated at 6000 watts at 208 volts will draw 28.8 amps.The CEC states that if a 208 volt rated motor is connected to a 240 volt supply its full load current has to be increased by 10 % for its overload protection.If the three phase source is delta connected, and the neutral/ground is at the center tap of one of the phase windings, then there is 208 volts available from neutral to the third phase leg. In this case, there would be no mismatch of voltage, and the 208 volt load will operate as designed.This particular configuration is not so common. It is sometimes used in a light industrial setting where a fourth transformer for the 120/240 split phase portion is not used - it provides 240 three phase delta only, 120/240 split single phase, residential style, and 208 single phase.See related links below (High Leg Delta)Note that 240 three phase loads are also not so common. In the case where 480 three phase is required in this configuration, then there is a step up transformer trio provided, ususally by the customer.
What size breaker for a 208 volt single phase motor that pulls 1.4 amps?
208 volts is not a common single phase voltage but you could just size your breaker to the capabilities of the conductor. 208 is normally a phase to phase voltage <<>> Many 230 volt motors can be connected to lower voltage supplies. These motors can be connected to supplies of 208 and 200 volts. The code requirement is that the 230 volt full load amperage of the motor be increased by 10% and 15% respectively for wire sizing and breaker selection. To answer the question you will need a two pole 15 amp breaker.
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%.
Can you convert 120 volts 1 phase into 208 volts 3 phase 40 amps per phase and would it be cheaper to get 208 volts 40 amps per phase installed in your house by electrician?
Answer for USA, Canada and countries running a 60 Hz supply service.To answer the first part of the question. No you can not convert 120 volts single phase into 208 volts 3 phase. In fact it is the other way around, the 120 volts is the line to ground (neutral) of a three phase 208 volt system.The second part of the question is dependant on there being a three phase 208 volt system already installed. To obtain 40 amps per phase would require a three pole breaker to be installed in a 120/208 three phase distribution panel.The distribution panel would most likely be in the 100 to 200 amp capacity range. This kind of installation would definitely have to be installed by an electrical contractor as inspections and permits would have to be taken out for the project.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.

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.
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.
