I have a metal encased electrical wire, I think its 14/3, how can I be

me what gauge they are?

Compare it to a wire that you know is either 12 or 14.

Or use a wire stripper: if you put 12-gauge wire into the 14-gauge hole on a
stripper, the teeth will cut through the insulation, and bite on the
conductor. Conversely, the teeth on the 12-gauge hole will not cut all the

way

through the insulation on a 14-gauge wire.


If you compare it to another wire, bend it. 14 bends easier than 12.


No need to bend it. A visual comparison is easily enough to tell the
difference.


If one has samples of both.
