Does any one know when the manufacturers started using different colors on the casing of “Romex” wires - I know it has been several years, but don’t know the exact date - ie. white- 14awg, yellow- 12 awg, etc.
Thanks in advance -
Thanks Mike - Knew it wasn’t that long ago but wasn’t sure when - this helps in doing panel inspections -
That last sentence in the reference is why you can never be 100% sure just by looking at the color - white Romex of many sizes is commonly found in installations.
