What size conduit and aluminum wire for a 400 foot run for 200 amps?

The question can't be answered without knowing what the voltage is. That is because the allowed voltage drop is 5% of the supply voltage, so you need to know the supply voltage. Then the wire calculation aims to find out what the minimum size of wire is that produces that voltage drop or less.


Why drop voltage in xlpe cable is more than PVC cable?

The voltage drop in a wire has nothing to do with the insulation. Voltage drop has to do with the cross sectional area of the wire.


Would using a 200 foot extension cord which is 6 gauge 3 wire cord on a 220 single phase welder present any problems?

Absolutely, you will have voltage drop, maybe enough voltage drop that the welder will not work <<>> To do a voltage drop calculation for the 200 foot cable the input amperage of the welder needs to be stated. At a maximum distance of 201 feet and limiting the voltage drop to 3% or less, a #6 copper conductor can deliver 37 amps on a 220 volt system. Check the nameplate on the welder to see if it falls withing the range of 37 amps input amperage. Do not use the welders output amperage.


What gauge of electric wire needed for a 160' run at 125 amps?

A 2/0 copper conductor will limit the voltage drop to 3% or less when supplying 125 amps for 230 feet on a 240 volt system.


Voltage drop not exceeding what percent is allowed for feeders?

According to the NEC (national electric code) a maximum of 2% voltage drop is allowed.

For voltage drop calculation you must use the current of the circuit breaker or the normal currents?

For voltage drop calculation you must use the current of the load and the distance of the load from the supply source. The circuit breaker is then used to limit the current to the rating of the wire that feeds the load.

What is volts drop?

the voltage drop means whenever the conductor passing through the supply voltage, according to the resistivity property to reduces the some amount of voltage that drop is known as voltage drop for example the resistance is used to drop the voltage to the circuit.............................................


What is the voltage drop using?

Voltage drop is caused by circuit resistance


The voltage drop in line can be decreased by?

What is voltage drop per foot?

Voltage drop is caused by resistance. From the equation V=IR the voltage across that resistance can be calculated. For a uniform conductor the resistance is linear with the length R=kx where k is in ohms per foot. For a given current, the voltage drop V=Ikx so the voltage drop per foot is Ik. Voltage drop per foot can be measured, allowing a calculation of voltage drop for very long lengths of conductor such as power transmission lines. This is a reasonable approximation as long as the total voltage drop in transmission is small relative to the supply voltage. If the voltage drop is large, the current will be limited by the total resistance. This implies that long distance transmission lines should be high voltage, because 1 megawatt at 10,000 volts requires 100 amps, while at 100,000 volts it only requires 10 amps. The voltage drop per foot for the same conductor would be 10 times as large at 10 times the current, and the power loss (I*IR) would be 100 times as large. For alternating current, inductance can be a factor; this implies that relatively low frequency would be preferred.


What is the effect of diode voltage drop as the output voltage?

The effect of diode voltage drop as the output voltage is that the input voltage will not be totally transferred to the output because power loss in the diode . The output voltage will then be given by: vout=(vin)-(the diode voltage drop).


What cause the voltage drop in shunt generator when its loaded?

because the voltage likes to drop


What size aluminum wire would you need to run 500 ft from the power pole to maintain 50 amp service?

This is a voltage drop question. To answer this question a voltage needs to be stated. This is a calculation for a 120/240 service. A 3/0 aluminum conductor will limit the voltage drop to 3% or less when supplying 50 amps for 500 feet on a 240 volt system.

What is the difference between voltage forward voltage and voltage drop?

Voltage is the potential difference between the source & any point in the circuit. The forward voltage is the voltage drop across the diode if the voltage at the anode is more positive than the voltage at the cathode (if you connect + to the anode). Voltage drop means, amount of voltage by which voltage across load resistor is less then the source voltage.


What effect does it have on the voltage drop in an electrical cable if the resistance of the cable is decreased?

It will decrease the voltage drop.
