No, lower voltage equipment will not operate on a higher voltage because the wattage or current drawn by the equipment will be higher that the rating of the equipment at the lower voltage.
For example if you take a heater rated at 5000 watts at 208 volts, the current is I = W/E 5000/208 = 24 amps.
The resistance of this heater is R = W/I (squared) = 5000/24 x 24 (576) = 8.6 ohms.
Applying 240 volts to this heater whose resistance is 8.6 ohms results in this new heater wattage rating. W = E (squared)/R = 240 x 240 (57600)/8.6 = 6697 watts.
As you can see the original wattage of the heater is overloaded by about 25% of what the manufacturers specified the wattage to be.
Ohms law states that the current is directly proportional to the applied voltage and inversely proportional to the resistance of the circuit.
W = watts, I = amperage, R = resistance in ohms and E = voltage.
What else can I help you with?
Can a 230 volt single phase watt hour meter be used to monitor 115 volt single phase?
Yes it would work pretty well but it might not meet its accuracy specification.
Does a two phase heater need a two phase thermostat?
Most electrical equipment are either designed to work on Single phase (two wires) or Three Phase (three or four wires). Two phase equipment are non existent today. A single phase heater will require a single phase thermostat while a three phase heater will require a three phase thermostat.
Will 120 volt equipment work on a 110 volt transformer?
Yes.
What is the 60 Hz on a welder with the listed input as 208 230 volt single phase 60Hz?
60 Hertz is the frequency that the welder should be connected to, to work as it is designed to.
Can you plug in a 240 volt equipment into 110 volt electric socket?
No, it won't get enough power and won't work.
What happens when a phase gets short and also when it get opened in a delta and star connection?
In star connection when two phase is short,it work as single phase system. In delta when one phase is open ,it work as a single phase.
What does 120 volt one phase mean?
If you are in the U.S., it means you can plug into the wall and it will work. The typical wall outlet is 115 volts AC and is a single phase supply. A couple of volts here or there doesn't mean anything to the appliance in question - whatever it may be.
Can you use a 6 volt adapter on 9 volt equipment?
No, the unit might work but the low voltage will cause unit to stop.
Does a 480 volt panel have a neutral bus?
Usually yes. A typical 480 volt panel is a 3 phase panel with 480 volts line-to-line and 277 volts line-to-neutral. However, I did once see a panel that was 480 volts, 3 phase, but because it served only motors it did not have a neutral. (a 3 phase motor doesn't use a neutral.) Similarly, if a panel uses only 2 legs of a 3 phase 480 volt system, which would be called single phase, it would not require a neutral if it only feeds 480 volt single phase loads. But I find the idea of no neutral to be extremely unusual and in my one personal experience, I blamed it on the age of the system. In 16 years of commercial and industrial construction I have never installed a 3 phase panel without a neutral and all my work is designed by engineers.
Can a home appliance work on 230 volt AC which is designed for 120 volt AC?
No, the voltages are too far apart. Some equipment can work on both voltages but they have a switch on the back of the equipment to change from one voltage to the other.
In what phase does electricity in US WORK?
Your home will have single phase power coming to it.
Will three phase power damage single phase appliances?
If you plug a single phase appliance into a three phase power supply, then you will be using single phase power. It does not matter if you are delta connected, AB, BC, or CA, or if you are wye connected, AN, BN, or CN. Yes, if there was "a problem", you would trip the supply. Question, however, is what do you define as "a problem"? Three phase power is intended to supply three phase appliances. Connecting a single phase appliance to three phase power is inconsistent with the objective, and such connection must have been performed by some kind of "jury-rigging". If you pull more than the trip current on any one phase, the supply should trip. If a malfunction in the single phase application, however, were to result in fault current that is lower than the trip current, you might not trip, and you might create damage and/or a fire. There is nothing wrong with building a branch circuit that feed a single phase load from one phase of a three phase source. You just need to provide the correct protection for that intended load.
