In electrical wiring awg ( American wire gauge) goes to 4/0 as the largest size. then it goes to 250 mcn. MCN which stands for 1,000 Circular Mils. this system uses the cross sectional area of the wire as a measurement. typical mcm wire sizes start at 250 and go to 300,350,400,500,600, etc. 250 mcm is usually good for a 200 amp service in aluminum wire in Canada per code. American standards are not as high or as good as Canadian ones. 250 MCM Welding cable is the next size larger than the standard 4/0 cables used on most standard mag particle inspection machines. Increasing the cable size will reduce the heating effect on the cables and increase the available current. welding cables is one of the more common uses for bigger sized wires.
250 MCM Cable has a cross-sectional area of .199 square inches
"0.5 mcm" is not a question.
TMC stands for Thousand Million Cubic Feet and MCM stands for Million Cubic Meter so 1 TMC= 28.31684 MCM and 1MCM = 0.035315MCM
250 x 250 = 62500
Any number multiplied by 250 will be increase by 250. 1 x 250 = 250 2 x 250 = 500 3 x 250 = 750 and so on.
68% of 250= 68% * 250= 0.68 * 250= 170
250 MCM copper wire weighs approximately 0.311 pounds per foot.
A 250 MCM copper conductor with an insulation factor of 75 or 90 degrees C is rated at 255 and 290 amps respectively
Using the AWG for wire sizes only goes up to 4/0. After that the increases use MCM to size the wire. So your 262 MCM wire size will be same in AWG. There is no 262 MCM in the North American market place. It goes in 50 MCM increments starting at 250 MCM , 300 MCM, 350 MCM, 400 MCM right up to 2000 MCM cable.
250 mcm
If you use 250 or 300 MCM wire you will need a 2 1/2" weather head. If you use 300 MCM wire then you will need a 3" weather head.
1 MCM means 1000 circular mils, and a circular mil is the area of a circle with diameter 1 mil ( that is 1/1000 of one inch). In metric terms, 1 MCM = 0.5067 sq mm
There exists split bolt connectors that handle that size.
