How does a single phase line to line circuit work if there is no netral?

You said it yourself. The power is from line to line, or more correctly, from hot to hot. There is no neutral involved.

What will happen if single phase load is connected to three phase circuit?
To obtain a single-phase supply from a three-phase supply, the single-phase load must be connected either (a) between any pair of line conductors, or (b) between any line conductor and the neutral conductor. Of course, the voltage obtained from either of these connections must match the voltage rating of the load.
Can an electrical short be caused a phase to a phase?
It could be a phase to phase, ph to neutral or earth fault. In single ph wiring ph to ph exhibits no short ckt faultAnswerYes, but you have got the terminology wrong. There is no such thing as 'phase-to-phase', the correct term being 'line-to-line'. So you can have a short circuit as a result of a line-to-line fault, a line-to-neutral fault, or a line-to-earth fault.
How three phase line current convert in single phase?
The current is the same in the three live wires. The voltage can be described as the line voltage (phase to neutral) or the phase voltage (phase to phase) which is larger by a factor of sqrt(3). So a line voltage of 230 v corresponds to a phase voltage of 400 v.
Is line to line fault a 3 phase fault?
'Line conductors' are the three 'hot' conductors (A-B-C) that connect a three-phase supply to a three-phase load. In some cases, a pair of line conductors (e.g. A-B, B-C, or C-A) is used to supply a single-phase load. A 'line fault' can be a short-circuit fault between all three, or any two, of these line conductors -whether they supply a three-phase load or a single-phase load.
Can you convert 415v 3 phase to 230v single phase?
415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
How many amps does a 2000 watt heater draw at 240 volts on each line?
For a single phase circuit, the equation you are looking for is I = W/E. Amps = Watts/Volts.
What is a single circuit?
is the measured voltage,generated between a line voltage and the starting point of a three phase transformer, which is the neutral point. Answer: it is an ac circuit in which the supply has a live and neutral wire, usually at one of the standard voltages 110/120v or 220/240 v. A three-phase circuit is a combination of three single-phase circuits with the phases of the voltages 120 degrees apart so that they peak in a regular sequence.
Why is 230 volts classed as single phase?
In Europe and other places the standard single-phase supply for houses and small businesses is 230 v which is derived from a 400 v 3-phase 4-wire supply by connecting each customer's circuit between one phase line and the neutral wire.
Can you use phase voltage as a single phase?
A single phase supply can be obtained between any pair of line conductors or between a line conductor and a neutral conductor.
What is the Single phase voltage in India?
The single phase voltage in India is 230v when we check with the phase and the nutral single line
Can you get 220 VAC single phase by using the ground and one of the hot wires in a 440VAC three phase circuit?
Use a transformer. A 208-240v single phase line has 2 power leads. Consult your local electrician for help! 440v systems are not for toying with when questions like this are asked.
Can a 3 phase contactor be wired for single phase?
Yes, L1 of the single phase supply is terminated under terminal L1 of the three phase contactor. L2 of the single phase supply is terminated under terminal L2 of the three phase contactor. A conductor from output terminal T2 is then taken to input terminal L3. The single phase load is then connected to the contactor's output terminals T1 and T3. This incorporates all three of the overload blocks on the contactor into the control circuit. With the overloads in the control circuit, if an overload occurs the magnetic contactor's holding coil will drop out and take the load off line.
