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
What else can I help you with?
What is the minimum size alluminum ground for a 200A service?
250 mcm
Convert 262 mcm to AWG?
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.
Can you legally splice 250 mcm and what would you use?
There exists split bolt connectors that handle that size.
What size aluminum wire for a 220v 200a service in conduit undrreground at 180 ft?
250 MCM aluminum minimum
What size service head is needed to power 250 amp 415 volt installation?
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.

How much does 250 mcm copper wire weigh per foot?
250 MCM copper wire weighs approximately 0.311 pounds per foot.
What does 250 mcm copper weight per-foot?
The weight of 250 mcm (thousand circular mils) copper per foot can be calculated using the formula: weight (lbs/ft) = (circular mils × 0.000001) × 0.321. For 250 mcm, this results in approximately 0.196 lbs per foot. Thus, 250 mcm copper wire weighs about 0.196 pounds for each foot of length.
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.
What is the ampere rating of 250 mcm inverter duty wire?
A 250 MCM copper conductor with an insulation factor of 75 or 90 degrees C is rated at 255 and 290 amps respectively
If you have a 400 Amp service using 500 MCM What size grounding electrode conductor is required?
For a 400 Amp service with 500 MCM conductors, the minimum size grounding electrode conductor required would be 3/0 AWG copper or 250 kcmil aluminum based on the NEC Table 250.66.
What size of breaker is use for 75 horsepower 220 volts 3 phase induction motor?
500 amp breaker with 250 mcm cu conductors, NEC list this motor as drawing 192 amps X 250% = 480amps go to the next standard size of breaker which would be a 500.
