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%.
What else can I help you with?
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.
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.
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.
What is 208 voltage star?
208 voltage star refers to a three-phase electrical system where the voltage between any two phases is 208 volts. This type of system is commonly used in commercial and industrial applications to power machinery and equipment. Voltage configurations such as 208Y/120V or 208/120V are typical examples of 208 voltage star systems.
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. Equipment rated for 208 volts and operated on 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.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.
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.
The power cable assembly connects to a power source?
208 volt, three phase
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.
Can you use 220 Volt 3 Phase as 208 Volt 3 Phase?
Yes by using a 3-phase transformer. The size depends on how much power has to be converted.
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 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 happens when 240 volt equipment is plugged into a 208 volt source?
It should be ok
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.
Can you run a 208 volt single-phase computer off 240 volt power?
No. The 1-phase 240 setting on your computer's power supply is for the 240V wall outlets in other countries. The 240 outlets in your home are 2-phase 240.
What is the voltage value between one leg of a 208 volt system and the ground wire?
Well if you are talking about phases, it would be half of 208V.
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.
208 volt 12 amps versus 277 volt 6 amps?
It is hard to see a question here. Both of these voltages are currently use in electrical systems today. Both voltages are related to three phase systems. A voltage of 208 volts is a three phase wye system that has a voltage of 208 between lines L1, L2 and L3 and 120 volts between any of the lines and neutral. A voltage of 277 is the line to neutral voltage of a 480 volt three phase wye system. There is a voltage of 480 between L1, L2 and L3 and 277 volts between any of the lines and neutral.
