Unknown Type Of Wire
Hello;
Need some help on identifying a type of conductor recently uncovered in house.
This wire is a two wire conductor with ground. It has one black, one white, and a bare ground. It is encased in a grey rubber(?) flexible material. I have shown a piece in several places and everyone shrugs their shoulders as they haven't seen it before.
This house had some wiring done a long time ago ) possibly late 60's/early 70's) and may have been installed then.
The wire on the conductors outside is 14 ga and bare is 16.( This was the subject of a related post ) Has anyone ever seen this wire before and is it safe to leave in place ? Circuit is hardly ever used.
WG?

Unfortunately, there is no official standardization for cable sheath colors. For instance, recently Romex brand cable has change the sheath colors to correspond to different AWG size.

UNKOWN TYPE OF WIRE
Hi Guys;
Thanks for replying. Ted, you are right. It is indeed a old type of UF 14 ga. wire. I was just concerned as I couldn't find any markings and it was a mystery to me.
At first look we couldn't find anything and some things I have come across in this house, built in 1927 , take some real investigating to trace and correct. There was no writing and no observable rating impressions on the wire. as this goes into a wall I was concerned for safety.
I finally found some markings on the wire by using an old impression revealing trick. I found a fairly accessible straight piece and lightly rubbed, going in one direction only, some white chalk on the wire. This revealed some very, very, faint impressions on the insulation.These were the markings I observed;
"E30445 (UL) AWG 14/2 with ground Type UF 600 volt Sunlight resistant".
This I can now feel easier that I can leave in place.
I am posting this in case anyone else ever comes across a similar problem , that this might enable them to more readily identify the wire type.
Thanks for your replies.
