Yes they can. There are regulations that cover most jurisdictions regarding how different cables can be contained. It is important that you are knowledgeable about your local requirements before starting the work.

How you convert the value of single phase power to value of 3 phase power?

Electric power is measured in watts. It does not matter if it is single phase or three phase. All things being equal, for the same load, the power measured in a single phase circuit or a three phase circuit, will be the same.


What is the weight of a single phase motor vs a three phase motor having same power?

They will not be very different.


What motor gets more heated single phase or three phase?

Your question is a little like asking, 'How long is a piece of string?'! Do the two motors have the same power rating, or are they different?The rate at which energy is used by any machine is defined by its power rating. If the power ratings of two different machines are the same, then both machines use energy at the same rate. So if a single-phase motor has the same power rating as a three-phase motor, then they will both use exactly the same amount of energy over a given period of time.So, if a single-phase motor has a greater power rating than a three-phase motor, then the single-phase motor will the greater amount of energy in a given period. On the other hand, if a three-phase motor has a greater power rating than a single-phase motor, then the three-phase motor will the greater amount of energy in a given period.


What are some advantages of 3-phase power over 1-phase power?

There are several advantages of 3-phase power over single phase power. First, with 3-phase power, more power can be transferred with the same amount of wire (meaning the amount of copper used in all of the conductors transferring that power) as with single or 2-phase power. Also, power is transferred more "evenly" with 3-phase power because the "next peak" is closer than it is with single and 2-phase power. The 3-phase motors run more smoothly than those run on fewer phases. Also, there are motor design considerations (one being control of the direction of rotation) regarding the motor that make 3-phase power more attractive. Use the link to the Wikipedia article on 3-phase power and skim it. It isn't long and it is quite readable.


Why is 3 phase more efficient?

There are a few reasons. In my opinion the most common is cost. In an industrial setting, three phase power is used to power motor loads. A three phase induction motor is more efficient than a single/split phase motor. They also have higher starting torque. A three phase load will also typically have a lower amp rating for the same size load as single phase. This saves money because you can use smaller wire.

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 a three phase circuit be installed in the same conduit or in different conduits?

The conductors of any three phase circuit must be run in the same conduit. If the circuit requires a neutral, it must also run with the conductors in the same conduit. (If they were to be run in more than one conduit or raceway, the circuit would not operate properly.)


Why would three phase be used instead of single phase?

Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.

Can you run different phases in the same conduit?

No, you cannot run different phases in the same conduit. In electrical systems, different phases must be kept separate to prevent interference and ensure proper functioning of the system. Mixing phases in the same conduit can lead to imbalanced loads, increased heat generation, and potential safety hazards. It is important to follow electrical codes and standards to maintain the integrity and safety of the electrical system.

What size conduit for 400amps?

The sizing of conduit systems that wire has to be pulled into is dependant on the physical size of the conductor being drawn into the conduit. The second governing factor is the conductor count of the specific conductor that is needed. A 500 MCM copper conductor with an insulation factor of 90 degrees C is rated at 430 amps. This is where the conductor count is need by the service, as to whether the service is single or three phase. In this specific case, the electrical code will allow both single and three phase installations to use the same size conduit. A maximum total of four 500 MCM conductors can be drawn into a 78 mm diameter conduit.

What are the uses of three phase transformer over single phase and their losses?

For a given load, a three-phase system requires around 75% of the volume of copper required by a corresponding single-phase system and, so, is more economical. A three-phase supply also delivers power more or less continuously, whereas a single-phase supply delivers power in pulses. Finally, three-phase motors are self-starting and physically smaller than single-phase machines of the same power rating.


Is a 2 phase supply the same or equivalent as 2 single phase supplies?

Not necessarily. Two single-phase supplies could be supplying the same phase, which means you don't get the same range of voltage options you get with a true two-phase supply.
