There are many types of three wire and four wire cables. There are many types of armoured sheath on these cables. The cables can have free air rating like NS75 quad, or hard drawn single conductor rack mounded conductors. The voltage rating of the cables plays a big part in the price of the cables. So to give a definite price without knowing more about the cable, a price can not be given.

When you have 56KVA available in 3 phase supply how much is your available current in 3 phase and how much in 1 phase?
In three phase: I = (three phase VA) / (sqrt(3) x (phase to phase voltage)) for single phase: I = (single phase VA) / ((phase to neutral voltage)) keep in mine three phase VA = 3 x (single phase VA), and phase to phase voltage = 1.732 x (phase to neutral voltage) Therefore the single phase and three phase currents are the same (ie, the three phase currents are the same in all three phases, or balanced). But don't get available current and available power confused (KVA is not the same as KW).
How much does it cost to run a 3 phase 9 kW heater?
The cost is set by the power, 9 kW, and the length of time it is used. This heater would use 9 units (kilowatt hours) for each hour it is switched on. Depending on the price the utility company charges you for their three phase rates times the length of time will give you the answer.
How much more power does three phase produce?
Single-phase and three-phase can both produce as much power as required if they are correctly designed. Three-phase is used for transmitting power over distances because more power can be transmitted for a given amount of wire. Take three single-phase supplies each transmitting 10 kVA as an example. They use 6 wires in total. Now make them peak out of step, 120 degrees apart in phase. Next, connect the neutral wires together at each end. It will be found that no current is flowing in the neutral wires, so they can be removed. Therefore you are transmitting the same 30 kVA using half the amount of wire by using the 3-phase system. Each live wire acts as the return wire for the other two live wires. This is important when transmitting power for many miles, when the wire is a significant cost.
Can you run a 570 volt motor on 480 volt three phase power supply?
No, the voltage difference is too much. A 570 volt motor falls in the 600 volt range which is separate from the 480 volt range of three phase systems.
How much breaker load Amps required for 31 kw?
Impossible to say without more details. It depends entirely on the voltage of the supply and whether it's single-phase or three-phase.
How much will it Cost to upgrade an electricity supply from phase 1 to phase 2 for a Melbourne home?
If you are asking whether it is possible to upgrade from single phase to two phase, then you should understand that a two phase system is archaic and will not be available from your electricity supply company. If you are asking whether your company can supply two lines (out of three) it's quite unlikely -they will normally supply single phase or three phase! You can likely upgrade to three-phase if you have a reason to do so -e.g. to operate three-phase motors. As for the cost -you'll have to check that our yourself!
How much does basic cable cost with quest tv?
You can purchase basic cable with quest TV for as low as 29.99. However the introductory rate changes after three months.

If the cost of fixing a defect in the requirements phase is 1 what is the relative cost of fixing a defect in the Testing Phase?
It is safe to estimate that the cost of fixing a problem increases by roughly an order of magnitude in each phase of development.requirements phase (cost 1)preliminary design phase (cost 10)detailed design phase (cost 100)coding phase (cost 1000)testing phase (cost 10000)So as an estimate if a problem is not found until test phase it will cost roughly 10000 times as much to fix as it would if the problem had been found in the requirements phase.
How much is basic cable?
The cost of basic cable varies between different companies. As of 2014, the average cost of basic cable is between $15 and $20.
How much step down transformer cost?
Your question is rather like asking, "How much does a vehicle cost?" Is the vehicle a bicycle or a jumbo jet? So, the answer to your question depends on (a) what you mean by a 'power transformer' (there are various definitions)?, (b) what are its power and voltage ratings?, (c) is it single phase or three phase?, and (d) are you including the cost of its cooling system?
How much does cable cost a mouth?
my cable, 239 channels, is $60 per month
What is the difference between three phase load and phase supply?
How much current equipments are drawing from three phases (combined or individual) is called three phase load and how much supply we are getting from source is called three phase supply. Ex. In INDIA single phase supply is 220 volt ac with neutral. So in three phase supply all RYB phases should be 220 volts ac with neutral individually. If we calculate with phase to phase than it shoulb be 415 volts ac.
Do cable companies charge more for digital cable channels?
Digital cable channels can cost more money. How much more they cost depends on your cable company, some companies do not charge extra.
How much does it cost to replace a throttle cable on a car?
Depends entirely on make of car. I did it recently on my Taurus, it cost 38 for cable and an hour of my labour.
How much is a three phase 20A motor in Australia?
Free
Can you replace a three phase motor 3 Hp RPM 1420 with a single phase motor for a planer?
Probably not. The single phase three horse power motor will be much larger in physical size than its three phase counterpart, and will probably not fit.
