In the US system, the hot phase is designated by a color other than white, except that bare or green is non-current carrying, or safety, ground. In a 120/240 split phase system, the most common home system, hot is black in a 120 volt circuit, and the two hots are black and red in a 240 volt circuit. Also, switched hot in a 120 volt circuit is red, but it does not really matter as the rule is "white is neutral" and "non-white is hot".
Can someone add to this, please, for the UK and other systems.
Answer'Phases' are not identified in three-phase systems. Colours, letters, or numerals are used to identify lines.The UK's and other EU countries' nominal single-phase supply voltage is 230 V at 50 Hz. The conductors are identfied as follows in line with EU standards:
- line (not 'phase') conductor brown
- neutral conductor blue
- protective conductor green/yellow stripe
For three-phase (400/230 V) systems, the line conductors are coloured brown, black, and grey.
Prior to the EU harmonisation requirements, the UK's single-phase conductors were coloured as follows, and these will be found in all installations that pre-date the EU requirements:
- line conductor red
- neutral conductor black
- protective conductor green
For three-phase systems, the line conductors were coloured red, yellow, and blue.

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.
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 single phase ac generator?
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
How do you change 3 phase to single phase for Henny Penny display warmer?
You can go to an electrical supply store and purchase a transformer that will work for youAnswerA single phase supply can be obtained by connecting the load between any pair of line conductors, or between one line conductor and the neutral -depending on the nature of your three-phase supply. The single-phase voltage must match the rated voltage of your warmer, otherwise you must use a transformer.
How do you convert a three phase power supply into single phase power supply?
You can take three separate single-phase circuits from a 3-ph generator. Just use one of the live wires plus the neutral to make a single-phase supply. <<>> A three phase generator does not have to be converted to single phase. In electrical terminology any two legs from a three phase system are classed as single phase. No matter what voltage the generator is producing, L1 - L2, L2 - L3, L3 - L1 are classed as single phase legs along with L1 - N, L2 - N, L3 - N. If the generator output voltage is not the voltage that you are looking for use any two legs of the generators output voltage and use a transformer to obtain the voltage that you need.
Is there a difference between three phase and single phase electrical supplies?

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.
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 is single phase ac generator?
It's an electrical generator converting mechanical power into electrical power. The electrical power comes out in the form of single-phase alternating current.
Can you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 hz supply?
No, you can not you change the wiring of a single phase appliance of 2.4 kw that works on 240 to 400 volts 3 phase 60 Hz supply. They are two different electrical systems.
When would a three phase supply be preferred over a single phase supply?
Bcoz in single phase if supply is interrupt or any trouble there is no power .but in 3 phase if 1phase supply gone we can manage it by other 2 phases
What is meant by electrical phase?
according to my research a phase in electrical engineering means a single line or a single way of transmission
What are the specific electrical requirements for a device that operates on 220v single phase power?
A device that operates on 220v single phase power requires a power source that delivers 220 volts of electricity in a single phase. It should be compatible with the voltage and phase of the power supply to function properly and safely.
