The following is pretty colorful but in reality you will see nothing as the safety equipment stipulated by the electrical code trips the circuit open before any serious damage is done. On a circuit that has tripped on a ground or phase fault the first thing to be done is isolate the circuit using lock out procedure. The trouble shooting equipment used is a megger. Once the fault is located and repaired, the circuit is re fused or the breaker reset, power turned on and an amperage reading is taken. If all the equipment is within the manufactures specifications the circuit is signed of as operational. To quote Billy Mays "KABOOM!". For any two or more phases to make mechanical contact in a three phase electrical system creates the ultimate dead short. This results in an immediate explosion with an arc flash brighter than the surface of the sun and a complete meltdown of the conductors and equipment. Simply put, you don't want to cross phases or allow them to make contact in any single or three phase system. This is the worst thing any electrician can do.

Is 10 kva supply to 3 phase load is equal to 10kva supply to single phase load?
Yes of course!! 10 kva electrical power is 10 kva electrical power either it would be three phase or single phase. But other factors i.e. current, voltage changes accordingly. Actually this question is quit confusable. Because in 3phase system, if each phase gives 10kva power (single phase power = 10 kva) then 3 phase power will be 10 X 3 = 30 Kva If we go leteratualy towasrds the question, then the asnwer will be - No. becasue 10 kva supply to 3 phase load will be 3phase supply(i.e440V) & 10kva supply to single phase load will be single supply (i.e 250V).
What is total voltage in 3phase supply when one of the phase becomes zero?
There is no 'total voltage' in a three-phase system. There are three line voltages and three phase voltages.
Is there a difference between three phase and single phase electrical supplies?
Yes, there a difference between three phase and single phase electrical supply services.
Can you get 180 degree single phase power from 3phase?
Rephrase your question so that it makes sense.
Will a 3 phase motor work on grounded B phase?
If the motor is connected to an ungrounded delta supply service there will be no effect on the operation of the motor. If the motor is connected to a wye system supply service and the B phase grounds out, the motor's overload protection would take the motor off line from the electrical supply.

How convert 1 phase to 3phase in aircraft?
The power is generated in the form of three-phase in aircraft, and this sytem has no problem in feeding single phase loads. To conserve mass in tansformers and motors the supply works at 400 Hz.
Can you have 2 3-phase sockets off the same supply?
Yes, it is possible to have two 3-phase sockets off the same supply, as long as the supply can handle the combined electrical load of both sockets. It is important to ensure that the electrical wiring and sockets are rated for the necessary voltage and current to avoid overloading the supply. Consulting with a qualified electrician is recommended to ensure proper installation and safety.
What is the difference between a single phase and a three phase inverter?
The Single and Three phase refer to Alternating Current electrical power supply outlet system and the corresponding equipment requirements. The single phase system is generally used thepower requirements are low or moderate as for household applications , while the Three phase supply system is used for High power industrial applications. Thenumbers of phases refer to Alternating Current Supply lines which are delivering the power or the sytem requirement of the equipment for operation. Thus a single phase supply cannot operate a three phase equipment or vice versa. However a ThreePhase supply can be used individually as Three different Single Phase supply systems In case of Three Phase systems the electrical supply waveforms are such that at any given instant there is a 120 degree phase difference between any two supply lines , which also results in higher magnitude of supply voltage than the corresponding single phase supply. Now refering to the inverter which is nothing but a device to convert the electrical supply from one source or magnitude ( typically DC from a Battery Bank ) to the required form and Magnitude. Thus it simply generates the equivalent electrical supply either as Singleor Three Phase , which ideally will be the same as available available from the wall outlet
How can you get 3 phase supply from single phase supply by using only transformers?
You cannot. By definition, the potential of each line must be displaced from each other by 120 electrical degrees, and this is only achievable from a three-phase source.
What are the drawback of single phase?
There are no drawbacks, single phase is used every day. It is the most commonly used electrical supply in the world today.
Can a 220 volt 3 phase motor be connected to a 208 3phase curcit?
Yes.
Can i run single phase dc motor from 3phase bldc controller. i m using single phase motor in motorcycle and controller from other electric vehicle. if yes please tell me how to connect it?
It is possible to run a DC motor on a 3-phase supply using a full-wave rectifier if the voltage is right.
What is the Max amp rating for 3phase dc motor?
the three phase dc motor never seen yet motor eaither 3phase m/r or dc motor.
What type of electrical current is needed for a single family grinder pump?
single phase supply is needed
