What wire color for 380v AC?
Use black wire and identify the phases with the proper coloured phase tape. American color convention: Brown, orange, yellow, but you CAN use anything but grey, white or green for the "hot"
How do you obtain a 230 volts single phase supply from a 400 volts three phase four wire supply?
400 volt three phase on a grounded system is 230 volt single phase, with each phase 120 degrees apart. So, if you have a 400 volt, three phase four wire service (grounded service), you can pull one phase off and reference to the neutral for 230 volt service. Note this may not allow 115 volt service, unless there is also a center tap for each phase.
Can you use 240 volt 3 phase to run a machine that is 240 volt single phase?
Yes, if the motor is rated 240 volts 3 phase.There is such a thing as 240 volt 3 phase power.However if you are asking if you can use 240 volts single phase on a three phase motor, then the answer is no.
What is the total of a phase to earth voltage on 11000 volts?
An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
What color wires for 220v?
Telling the colour of wires has nothing to do with using a volt meter. Phase wire colours can be any colour except green and white. Usual 3 phase colours are red, black, blue. Single phase colours are usually red and black. Neutrals are always white and ground wires are always green or bare.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no

On a 220 volt electric motor which is the neutral wire L1 L2 or L3?
If the motor wire numbers are L1, L2 and L3, it is not a single phase motor. It is a three phase motor. Also for future reference, a 220 volt single phase motor does not use a neutral.
How do you get a 220 volt single phase from 380 volt 3phase synchrounos generator?
220 volt single phase from 480 volt 3 phase that one wire taken one phase and second wire connected in earth point. we get 220 v The above answer is incorrect, one phase from a three phase 480 volt system will give you 277 volts to ground. You must use a transformer to get the voltage you need.

Can you tap off a 3 phase 277volt ac light fixture to power a single phase 120 volt ac recptacle?
NO! The voltages available in the 3-phase system are 480 (if you wire phase to phase) and 277 (if you wire phase to neutral) Don't try it!
Which color wire is normally hot on a 120 volt system?
black
In a three phase four wire wye system having 277V for lighting the three phase motors operate on what voltage?
480 Volt

An 11,000 volt three-phase supply has a voltage of 6351 from live to neutral, when there is a neutral wire.
What size wire do you need for a 200 Amp 240 Volt 3 phase 4 wire service on a doctors office?
You might be out of luck. Three phase delta 240 volt services are a thing of the past. As far as I know there never was a 240 volt three phase four wire. The line to neutral voltage would be 240/1.73 = 139 volts which is of no use to anyone. Three phase four wire system for business and commercial use these days is 120/208 volts. A 3/0 copper conductor with an insulation factor of 90 degrees C is rated at 225 amps.
