Mineral Insulated Cable Ampacity Chart

Table 310 15 b 16 formerly table 310 16 allowable ampacities of insulated copper conductors rated up to and including 2000 volts 60 c through 90 c 140 f through 194 f not more than three current carrying conductors in raceway cable or earth directly buried based on ambient temperature of 30 c 86 f.

Mineral insulated cable ampacity chart.

However the terminations are only rated for 75 degrees c. Nvent pyrotenax cables are approved to push more power through a smaller area saving space in your overall design. 2 hour fire rated mineral insulated copper sheathed wiring cable description pyrotenax system 1850 mi cable is fm specification tested and classified by underwriters laboratories as 2 hour fire resistive. Current is measured in amperes or amps.

Home products our products lie in the walls of your home in the transmission lines that power our neighborhoods in the places we work schools where we learn and the hospitals that keep us well. Organic construction also means mi cable is an environmentally friendly option and does not burn produce smoke or contribute to ongoing fire emergencies. Southwire is one of the world s leading manufacturers of wire and cable tools components and assembled solutions. When installed in accordance with pentair thermal management installation procedures the result is a ul ulc 2 hour fire resistive system.

You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating. The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
