Mineral insulated cable ampacity chart.
Organic construction also means mi cable is an environmentally friendly option and does not burn produce smoke or contribute to ongoing fire emergencies.
Other benefits of mineral insulated copper cable include.
The number and type of electrical devices connected to a circuit determine the ampacity requirement of the conductor.
Usually a general purpose house circuit is designed for 20.
The 500mcm mineral insulated cable we have specified has a table 310 16 ampacity of 430a at 90 degrees c.
However the terminations are only rated for 75 degrees c.
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.
You must use the correct size wire for the current load requirement of the circuit to prevent the wire from overheating.
