Which cable is suitable for 12kW?
It depends on the voltage and on whether it's single-phase or three-phase.
Why armouing is not done in single core cable?
On the contrary, armouring is common on single-core conductors. Frequently, high-voltage underground cables are made up of three, individual, single-core, line conductors. These are most definitely armoured to protect them against penetration by the trench backfill and to protect workers who may accidentally hit them with tools.
How many wire or core in three phase electrical connection and single-phase electrical connection?
A single-phase cable will have a line and a neutral conductor and, possibly, but not necessarily, an earth (ground) conductor. A high-voltage three-phase cable will have three line conductors. A low-voltage three-phase cable is likely to have three line conductors and a neutral conductor.
What is voltage loss?
It's when there is a supply with a given voltage, and then a piece of equipment is fed through a long piece of cable so that the voltage supplied at the equpiment is somewhat less. The voltage drop is the amount of reduction caused by the resistance of the cable. Voltage drop should be less than 5% of the nominal voltage, e.g. 12 v for a 240 v system.
What AWG cable for 200' x 208 volt three phase 250 amp circuit?
A wire size of 250 MCM will limit the voltage drop to 3% over a distance of 200 feet.

How much does three phase cable cost?
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.

How many wires are used to wire a standard dryer?
In North America you would use a three wire cable. A dryer needs two voltage supplies. A 240 voltage for the heating element and 120 volts for the motor and controls. The three wire cable will have a ground wire in it also but in North America this is not counted as it is not a current carrying conductor. The size of the cable will be a 3C #10.
What is the voltage rating of the conductors in type nmc cable?
In North America the voltage ratings of low voltage wire comes in three voltages. The voltages are 300, 600 and 1000 volt insulation ratings.
What is wye delta motor control?
It is a method of starting a three phase motor at a lower than operating voltage. The motor is operated at that voltage for a short specific time and then the controls switch to the motors full run operating voltage.
Is any voltage drop over a 200 meter overhead cable if you have a 440 three phase system?
There is voltage drop over any sysetm that does not have infinitely low resistance, but with reasonable cable size there would be very little drop over 200 metres. The number of phases makes little difference.
Should armoured cable be buried a certain depth?
Armoured cable is not rated for direct burial. Use a cable that is rated for direct burial or use a PVC conduit to pull the cable through. PVC burial is two feet, three feet if vehicular traffic will pass over the conduit.For more information please click the middle buttonbelow.If the site is in the UK, to comply with the latest Wiring Regulations it is essential to install an RCD to protect the buried armoured cable and the associated external light fittings.For more information please read the Related link shown below the Related questions for this answer.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.IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOBSAFELY AND COMPETENTLYREFER THIS WORK TO QUALIFIED PROFESSIONALS.

What size tech cable for 480 feet 100 amp?
This is a voltage drop to establish wire size question. For a correct answer to this question two values are needed. One value needed is the voltage and the other is whether it is three phase or a single phase installation.
Why do you use a three wire cable?
A three-wire supply is used for a split-phase 120/240 v supply with two lives and a neutral. The voltage from each live to neutral is 120 v while the voltage between the two live wires is 240 v.
