Where can I find a list with the characteristics of different types of wires (type of insulation, temperature rating, manufacturers, etc) that are usually found in the NEC?

Hi, Dannynicolae!

The following site might be a good start to find information about that.

Electronic Wire on ThomasNet.com (http://www.thomasnet.com/products/electronic-wire-94480407-1.html)

Hopefully, others will also come along to address your question.

Thanks!
