Electrical wires have markings stamped or printed on the outside sheath of the cable. These markings tell what type and size of wire that you have. But looking deeper, the color of the wires inside of the sheath, like in type NM cable, will reveal that different color wires serve different purposes. The question is, do you know what the wire colors mean?

Hey there! I could have sworn I’ve been to this site before but after reading through some of the post I realized it’s new to me.
Anyways, I’m definitely happy I found it and I’ll be
book-marking and checking back often!
