Best Answer

Electrical appliances usually have a metal plate with electrical specifications - you can look for that. Otherwise, you can use the relationship:

watts = amperes x volts x power factor

Power factor is usually close to 1; in this case, this simplifies to:

watts = amperes x volts

Volts are usually around 110 or 220 volts, depending on the region.

A polynomial of degree zero is a constant term

The grouping method of factoring can still be used when only some of the terms share a common factor A True B False

The sum or difference of p and q is the of the x-term in the trinomial

A number a power of a variable or a product of the two is a monomial while a polynomial is the of monomials

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.


How do you calculate the feeder size for two or more three phase air condition?

Feeder sizes are based on the amperage of the connected load. Once that is found there are tables in the electrical code book that state what the wire size is for that particular amperage.


If you have a 3 phase and 120 volt per phase electrical source how would you connect a heater element requiring 208 volts?

Answer for USA, Canada and countries running a 60 Hertz supply service.It sounds like you have a three phase system to connect to. If it is 120 volts from phase leg to neutral then the three phase system is 120/208. To connect the heater to a 208 supply on the distribution panel connect the load across a two pole breaker. The amperage rating of the breaker will depend upon the wattage of the heater. Amps = Watts/208 volts.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-energizedIF YOU ARE NOT REALLY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.


Can you run two 2 pole single phase circuits in the same conduit?

Yes, this only adds up to four wires. The wire sizing is dependant on the amperage of the two single phase loads. Remember to calculate the conduit fill of the four wires to make sure that you have the correct size conduit for the installation.


Can you run a motor of greater amperage draw with a motor of less amperage draw?

It looks like you are asking if a higher amperage motor can replace a lower amperage motor. It depends on what the amperage difference is. If the amperage is high enough to move the capacity of the wire out of its rated value then it should not be done.Remember motor conductors have to be rated at 125% of the motors nameplate amperage. As the amperage increases so does the HP and the motor's protection will also have to be increased or the motor will trip the lower overload protection settings.Also keep in mind that if the motor is three phase, running a motor with higher HP on a load that does not need the extra HP, it will lower the power factor of the supply distribution.


Two phase instruments?

There is no such thing as a two phase instrument. There is only single phase and three phase. You can only have: single phase/ one pole single phase/ two pole three phase/ three pole


How do you wire a two phase outlet for a stove?

Nobody supplies "two phase" power (it is only single-phase or triple-phase), so there would be no reason to connect to "two-phase".


Why Scott connection is used to convert three phase to two phase why cant you take two lines from three phase circuit?

In a two-phase connection, the phases are displaced by 90 degrees. Two lines (not 'phases') of a three-phase system will provide a single-phase supply, not a two-phase supply.


What is the advantage of using two phase in single phase motor?

Two phase motors are a thing of the past and are not used today if any still exist. Two phase legs are classified as a single phase system. If the question refers to a dual voltage motor then the answer depends upon what supply voltages are available to operate the motor. Operating a motor at the higher of the two voltages means that smaller control equipment and wire feeders can be used to operate the motor. If the nameplate is checked, in the amperage box there will be two current ratings, Amps/Amps. One will be half of the other one. Look at the supply voltage box and you will see the corresponding Voltage/Voltage. The first number in the voltage box corresponds to the first number in the amperage box. The higher the voltage the less line loss will occur over a distance. If possible always try and use the highest voltage to operate motors.


What is the voltage level of two phase machine in three phase?

From one phase to the next you should see 208 Volts.From any phase to ground you should see 121 Volts.AnswerYou are very unlikely to come across a two-phase machine, as two-phase a.c. systems are archaic. A two-phase system has two phase voltages that are 90 degrees out of phase with each other, and was used many years' ago. These days, you have either single phase or three phase. So it's probably safe to say that there are no two-phase motors about, these days!


What are the disadvantages of a two phase AC motor over a three phase and single phase AC motor?

The main drawback is that two-phase systems are archaic, and you are unlikely to find one with which to supply a two-phase motor.


How is a three phase motor different from a single phase motor?

The sine waves of a 3 phase power supply are 120 degrees apart, in a single phase supply they are 180 degrees apart. Three phase motors also consume almost half the amperage of the same HP single phase. Simply put, there are three "power" wires for the 3ph compared to the two for 1ph. 3ph induction motors do not use capacitors or separate windings to get them turning as 1ph motors do, therefore less separate/moving parts to contend with.
