The weight of one foot of 500 Mcm copper wire is 1.544 lbs.
What does 500 MCM stand for?
Measurements. Thousand circular mils or kcmil, the wire gauge is equivalent cross sectional area (500 MCM = 500,000 circular mils) Million cubic metre, the unit of volume.
What is the maximum ampacity of a wire?
Maximum Ampacity: 25 Amps Note: These values are based on allowable ampacities of insulated conductors rated up to and including 2000 volts, not more than three current-carrying conductors in a raceway, cable, or Earth, single-insulated conductor in free air, and an ambient air temperature of 30°C (86°F).
How is the ampacity of a conductor measured?
Ampacity is the maximum current that a conductor can carry continuously under the conditions of use without exceeding its temperature rating. Current is measured in amperes or “amps.”
What is the National Electrical Code allowable ampacities of insulated conductors?
National Electrical CodeAllowable Ampacities of Insulated Conductors Rated 0-2000 Volts As Excerpted from the 2002 National Electrical Code Ampacities of Not More Than Three Current-Carrying Conductors in Raceway, Cable or Earth. Based onAmpbient Temperature of 30°C (86°F)
How can I find out the ampacity of a wire?
Our new Ampacity Calculator app can help determine the ampacity of conductors in conduit, cable, or directly buried wires. Cerrowire markets through a number of quality retailers and manufacturer’s representatives.
