Depends if it is the supply cable you are wiring or a cable to the outgoing side. If it is the supply cable you are connecting, call your electricity supply company. They are the only ones authorised to do that work. <><><> Three phase will be at 415V. So proceed with caution! If you want to install a new branch circuit cable you need to be sure you have a three phase supply with a triple pole breaker. If you don't know what you are doing then don't try it as you can easily damage the equipment or yourself! Call a licensed electrician to advise you and quote for doing the job safely and correctly. <><><>
As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed.
Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized.

More answersFor a three-phase, four-wire, system, a single-phase supply can be obtained by simply connecting that load either (a) between any pair of line conductors (there is no such thing as a 'phase' conductor!), or (b) between any line conductor and the neutral conductor. Of course, the voltage rating of the load much then match whichever voltages (line or phase) are available from the three-phase supply.<><><>
If you hook a single phase load up to two lines of a 3-phase supply, that means you will be connecting the load's neutral connection to a hot line wire, something the manufacturer never anticipated. This could make the appliance unsafe, and hurt or injure someone.
Could the load device be modified for this application? Possibly. It would take a qualified professional to see your application with his own eyes to be sure.
In most cases, a transformer needs to be installed by a licensed electrician so as to do it safely.
If you have a 3-phase, 4-wire supply, this becomes a lot easier, as long as the voltages match. Bottom line, a qualified electrician needs to have a look.

∙ 12y agoA 3-phase load can be 3-wire ( phases 1,2 & 3)or 4-wire (as 3-phase plus a neutral - almost certainly plus an earth for each type. The load has to be connected in the correct order otherwise (eg) motors will turn in the wrong direction. Otherwise, it is much like connecting a single phase load, except there are 3 line conductors.

∙ 9y agoA three phase supply is usually carried on four wires, with one neutral and three live wires. Single-phase loads are normally connected between the neutral and one live wire.
This system can be seen in European streets where the supply is still overhead. The three-phase power supply is carried on four overhead lines, on wood poles, and each house has a two-wire supply connected to it.
Three-phase works by having the three live voltages phased 120 degrees apart, in other words peaking in turn through the AC cycle. If the loads on all three phases happen to be equal, the effect of the phasing is that the current in the neutral is zero. In other words each live wire acts as the return wire for the other two.
In this way power lost in the wire resistance is reduced, and this is why three-phase power transmission is common throughout most countries of the world.

∙ 14y agoYou should strive to get the supply conductors drawing all the same current. On a wye panel board this can be checked by having the neutral with a zero current draw. Balancing a panel board can be tricky as you have to move the load breaker positions around the board. It is even more trickier when some of the loads are intermittent. Try it on paper first. Write down the load wattage of the devices and then see what kind of configuration you can come up with on paper. When you are satisfied on paper, move the breakers and see what kind of results you end up with. You may have to fine tune it a bit as the single phase loads will never be exactly on. You will never get an exact balance unless the panel is all three phase loads all drawing the same amperage.

What does A three phase load requires a minimum of?
Yes, the minimum is three wires, usually used when the three phases are in balance, with equal currents in all three lines. In conditions when the three phases might be unbalanced, a neutral wire is added, which makes it a 3-phase 4-wire system, and the current in the neutral depends on how out-of-balance the currents in the three lines are.
How should the resistance reading compare in each winding of a three phase motor?
The three windings are made the same to maintain a balance in the motor.
What will happen if apply two phase supply to a three phase transformer?
A three phase transformer is simply three transformers so, supplying one phase to a set of three transformers will result in only one phase output. Any loads connected to that transformer that are expecting three phase power will malfunction, and could fail.AnswerA three-phase transformer is NOT 'three separate single-phase transformers', as suggested in the original answer. It is a single transformer with three primary and secondary phase-windings wound around a common three-limb ('core') or five-limb ('shell') core. If a single-phase supply was applied to one of the three primary windings, then single phase voltages would appear across each of the three secondary windings and the remaining two primary windings. These voltages would not be out of phase with each other.
What are the three types of phase on its final phase?
single phase, double phase & three phase
Can you put one phase of a three phase ditribution board through a contactor so that the other phases stay on?
Yes, but you must have your neutral wire to form a return path for your current.

Would a row of washers with inverter drives connected to single phase panel board cost the same to run as it would set up on three phase panel board?
three phase would be cheaper for running motors are more efficient single phase is only used for small motors and loads where operating economy is not a concern
What does A three phase load requires a minimum of?
Yes, the minimum is three wires, usually used when the three phases are in balance, with equal currents in all three lines. In conditions when the three phases might be unbalanced, a neutral wire is added, which makes it a 3-phase 4-wire system, and the current in the neutral depends on how out-of-balance the currents in the three lines are.

How should the resistance reading compare in each winding of a three phase motor?
The three windings are made the same to maintain a balance in the motor.
Why do you balance single phase loads across a 3-phase supply system?
On a Delta 3-phase you connect the single phase loads between pairs of the 3-phases. Warning both sides of these loads will be hot! You may want to use 3 isolation transformers so that the real loads have a neutral line.On Y 3-phase you connect the single phase loads between one of the 3-phases and neutral.In each case to balance the loads, try to put similar loads on each phase (or pair of phases).
What is mean by 7segment distribution board?
A distribution board which has 7 segments , one for Main incomer, three as sub incomer for each phase and three for singlephase outgoing is called a 7 segment DB

What will happen if 2 phase load is connected to generator?
There is no such thing as a two phase load any more. Any two legs from a three phase system are classed as single phase. If this single phase load is connected across the generator it will induce an imbalance in the output voltages of the generator. This is one reason that single phase loads on a three phase generator should be shifted around to find the best possible balance.
