000 <<>> A 750 MCM copper conductor with an insulation factor of 90 degrees C is rated at 500 amps.
plz tell me about 750 kcmil copper conductor
750 MCM (61 strands) 2.316#/ft 750 MCM (7448 strands) 2.719#/ft
The diameter of an insulated 750 MCM copper wire is 1.25 inches. The insulated 750 MCM copper wiring has 61 strands and has a weight of 2.7 pounds per foot.
Volume = Area*Length so Length = Volume/Area = 750/15 = 50 metres
750,000 circular mils. A wire that is 1 mil (.001 inches) in diamter is defined to have an area of 1 circular mil. The area in circular mils = (diameter in mils) ^ 2. To convert this to area in square inches, multiply 750,000 * pi / 4,000,000 = 0.589 sq in.
It depends on the value of voltage being applied to the wire in normal use. Voltages up to 750 volts can be used on wires reading as low as .5 meg ohms. Engineers like to see 5 meg ohms on conductor readings.

The larger the number of the wire, the smaller the amperage that it can carry using the AWG wire identification system.In the electrical trade the smallest building conductor that can be used is a #14 copper conductor with an insulation rating of 90 degrees C and is rated at 15 amps.The largest building conductors that can be used is a 200 MCM copper conductor with an insulation rating of 90 degrees C and is rated at 750 amps.The above ratings are for allowable ampacities for not more than three copper conductors in raceway. For amperages higher than 750 amps the conductors then become paralleled, tripled and quadrupled.There are other ratings for conductors such as free air rating (question for another day) but these are the ones used by electricians on a daily basis
#6 copper wire has a resistance of 0.3951 ohms per 1000 ft (from wire tables). A 750 ft circuit contains 1500 ft of wire so the resistance is 0.5926 ohms. With 65 amps flowing the voltage drop is 38.5 volts. The power lost in the cable is 2½ kW.
