Updated the Electrical Course: Size of Wire vs. AWG

We made an update to InterNACHI’s free, online “How to Perform Residential Electrical Inspections” course to help explain the relationship between size of wires and AWG.


Also, NEC makes a good phone app that calculates the size of wire by temperature. It is only a few dollars.

I can’t seem to find it…I have android :roll:

Do you all know the history of why they call it AWG? Quite interesting in fact.

Why Paul???
