It's highly probably that the '240 V' refers to the machine's phase voltage. In which case, its line voltage will be 1.732 times larger -i.e. 415 V. Phase voltages are measured between any line conductor and the neutral conductor, whereas line voltages are measured between any pair of the three line conductors.

∙ 14y agoA 240 volt 3 phase 3 wire grounded B phase system is also called a quadraplex configuration. You actually have four conductors, not counting the protective earth ground, which makes five wires.
Three conductors are the individual phase hots, A, B, and C. You can use them delta only, and you will have 240 volt three phase.
The fourth conductor is neutral, and is connected to the center tap of one of the Transformers, and also grounded at the distribution point. You then have 120/240 volt split phase with that neutral and the two hots surrounding it, which is the normal residential configuration for the US.
You cannot connect a three phase load in wye configuration, because the neutral is not in the center of the power triangle. If you want a wye configuration, you will need three more transformers, with the primaries delta and the secondaries wye.

What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
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!
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.
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.
Why does one line of 3 phase 480v show 0 volts and the other 2 have 480?
My first thought is this is probably a corner grounded delta system, but I'm confused by your voltages. If this was a 460v (L-L voltage) ungrounded or corner grounded system, the phase to ground voltage is meaningless, but the phase to phas voltage will be 460v all around the delta. If you have a 460v system and you're only seeing 230v, there's something wrong.
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.
What is the minimum volt rating of wire used in a 3 phase 4160 volt phase to phase system?
5000 volt
What conductor should be grounded in a four wire three phase system?
The neutral.
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.
Can you wire up a 240 volt single phase water heater to 277 volt single phase?
no
In a three phase four wire wye system having 277V for lighting the three phase motors operate on what voltage?
480 Volt
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!
How do you tell if the ground wire is bad?
If the voltage between real ground and the ground wire is not 0.0000 Volt, then the wire is not grounded properly.
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.
Do you get a shock when you touch the phase wire of single phase?
Only if you are grounded and provide a return path for the current to travel.
Why is it stated - 3 phase 440 VAC when one phase voltage is 220 VAC?
In three-phase there are three live wires and a neutral. The voltage of a three-phase system is always quoted as the live-to-live voltage, and the voltage from one live wire to neutral is 57.7% of that. A 440 v 3-ph system has 254 volts between live and neutral. <<>> The question statement is not correct. Two legs from a three phase three wire 440 volt system will still be 440 but classed a single phase. On a three phase four wire system supply, the voltages will be determined by the following equation. 440/(square root of 3) 1.73 = 254 volts. The second single phase voltage attainable from this source connection is any one of the three phase legs to grounded neutral center point. This is known as a wye or star point connected voltage supply. To obtain a 220 volt single phase voltage, the three phase system would have to have a voltage of 220 x 1.73 = 380 volts.
Which wire is the neutral wire in a 110 volt system?
White.
