I purchased two 1000 ft spools of cat 6a cabling. They were both supposed to be 23 awg. One appears to be thicker than the other. Is there a tool that measures awg?
There are wire gauges which are just metal plates with holes in them. Are both of the wire spools pure copper and TIA certified?
A $20 digital caliper would be the simplest and most reusable tool.
