As a retired weed grower I have purchased many rolls of romex and given many used rolls to my electricians who installed and upgraded old systems

Just so there is no confusion, Romex is a name brand for Non-Metallic Sheathed cable or NM cable, Like Scotch Tape, Band-Aid or Xerox, but we tend to use the brand name as the name of the actual item, This is called a product Eponym.

[MrShankspony]

Thank you for the straight forward explanation!

[chriserickson]

Thank you for the education. I never knew about all the different wires. I'm hoping to install a sub-panel in the Garage and this is a good start in understanding the wiring.

[Joellyboy]

ALERT FYI TO ALL:

The grey outdoor wire is currently cheaper then the indoor wire. $54 for 14/2 grey
$78 for 14/2 white

Good basic info, you might mention wire type inside: THHN, THWN and temp rating.

[jamesrobinson]

There is older romex that is colored differently also. I live in an older home and there is some 14-2 that is black and there is some 12-2 that is white with green lettering while the older white 14-2 or 3 has red lettering.

[NavjotSingh-orrr]

hello we are installing a one outdoor outlet and 2 outdoor lights what wire is good for that??

[harrydoherty]

new ranges require 3 wires plus a ground to meet code.the jumper on the ground to neutral is removed to acomadate the 4th wire.

I am looking for pictures to see thw difference between NM and NMC...do they look exactly the same only that on NMC it has the corrosion resistant overall?

[moemoes]

Great tutorial. Nicely explained. Thanks.

[NESDwayne]

My house was built in 1976. I have white romex clearly mark3d as 12 2. White does not always color coordinate as 14 gauge.

[ZJMK]

Thank you for this video. It helped a lot.

[VPDesigns]

This was really helpful. Thank you!
Do you have a video to explain the electrical differences between why some wires i.e speaker wire. Security wire, thermostat wire, are labeled as with the same agw/conductor wire is labeled as the same with for example: one label has 14-2 as speaker wire then there another labeled as 14-2 electrical wire, or 18-2 speaker wire, and 18-2 labeled as sprinkler wire so forth and so forth. Just wanted to understand how and why there are labeled as for such uses but have same awg/conductor? Also what is best explanation on stranded wire vs non, shileded vs non shielded, also what does solid copper vs non solid mean? .
