It depends entirely on the electrical standards of the country in which you live. The first answer describes the situation in North America. The European standard is brown-black-grey for residential systems; the UK transmission/distribution system still uses red-yellow-blue, although it will no doubt adopt brown-black-grey to fall into line with European Fourth-Reich requirements. Other countries, such as Australia and New Zealand use yet other colours. And the first answer is where?

What color is A phase on a three phase busway?
The colour phasing of a three phase electrical bus differ in different countries. In Canada the colour coding is A = Red, B = Black, C = Blue.
How do you wire a 2 phase network cable?
More information needed - is it a network cable (ethernet) or a 2-phase power supply (unlikely) . .
What is typical single phase voltage in Canada?
The standard nominal voltage in Canada for a single-phase residential supply is 240/120-V split-phase supply.
HOW and Why there is 440v supply in three phase and 230v supply in single phase?
because all over the world there is an standard rate of voltage
Can a single phase supply be used in a three phase supply?
Yes. This is often done in distribution boards.

How do you wire a 2 phase network cable?
More information needed - is it a network cable (ethernet) or a 2-phase power supply (unlikely) . .
You have three phase electric load of 29.3Kw what is thesuitable cable to feed this load if the distance between the supply and load is 270metres?
yes
What size swa cable is required to supply a door heater carrying 18.9Amps per phase?
Cable for 19 amps continuous should have a cross-section area of 6 mm2.
What should a officer look for while on patrol at a office building?
(1)First of all an officer should look for the colour coding i.e Load balancing in it is single phase and colour coding inside the flats if it is three phase connection. (2) Secondly, it should check the neutral and earth codings and connections. Phase should never be looped except multiple connections, neutral & earth can be looped depends of consumer requirements. Load balancing should be checked in bothe cases i.e on DB and on Panel.
What activities are done during the coding phase?
programming
How many meters can you run single phase 240v to another house?
Like all supply cables, it all depends on the CSA of the cable
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 phase sequence in a polyphase system?
It is the colour coding of the wires from left to right when connections are made to terminals. In Canada it is Red, Black, Blue. By using this standard every connection in the poly-phase (3 phase) system will be the same. Once a motor is phase rotated and marked with the appropriate colours it can be reconnected any where else in the system and run with the correct rotation.
What is the requirement of three phase to five phase transformation?
If you want a five-phase supply you need to start with a three-phase supply and a transformer that has 15 symmetrical cores. But why would one need a five-phase supply . . three is enough.
How do you start a three phase motor to a single phase power supply?
You don't. A three phase motor will not start unless it is connected to a three phase supply.
How do you calculate 3 phase load from single phase values?
If you have three adjacent houses each with a single-phase supply taken from different phases in a three-phase cable in the street, the total power is equal to the sum of the powers in each of the three phases.
