Different Types of Romex Wire or NM Electrical Cable

[@kiloton1920]

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

[@mikenormandy9250]

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.

[@garbo8962]

Same thing as wire nut. No such thing in NEC called a wire nut because its the name of a certain company. Heard Romex came from old Rome wire company. Was told at an IAEI class that BX got its name due to it was the second trial version that a comoany was playing with. The X in BX stood for experimental. That & $2 will get you a coffee.

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? .

[@artsoto5459]

Great video! What size wire do I need to bury for a 60ft line, it's gonna power up a 15 amp mini split, AC/HEAT, its 110 v and 15 amps, I also want to power 8 outlets and 3 lights, no appliances will be hooked up in my shed, at the most a 60 inch TV, no major tools or anything, the shed is basically a gym/entertainment area, it's a straight shot, therefore I'm thinking of using pvc conduit, also, I will not have it inspected, any ideas?

[@PhillipBridgesReviews]

Go with 10 AWG wire. It will do 30 amps. Plenty of power. You could do a little sub panel out in the shed. Make the 30 amps 220 volt panel with 4 breaker spots. Then add your 15 amp breakers off the sub panel.

I'm looking to turn my shed into a man cave it's about 150 feet from the house what wire should I use to run power to it, I wanna put a ac unit,mini fridge and tv with a few outlets?

[@PhillipBridgesReviews]

Depends on how big of AC unit you are going to have. With voltage drop 8/3 wire would work for a 110volt window AC and running a few outlets. You could put a little 30 amp sub panel out there 220 volt and add a few breakers off that. Check local codes. 8/3 underground would do or would have to be piped in some areas.

Can I use grey Romex in doors in the same way I would use the other Romex not intended for burial (if the AWG is correct for the circuit)? I often see the grey Romex cheaper in price for the same AWG, number of conductors, and length than "normal" inside Romex. Seems backwards.

[@benkanobe7500]

For a sub panel (provided the AWG is correct) where I have to go through 2x4 studs and can not go up into the attic, across, and down to the sub panel from the main, can I strip the Service Romex down to its conductors and run the conductors through the 2x4s from the main panel to the sub panel??

I found an open splice under my kitchen sink cabinet that was arcing and making a sizzling noise. Not only was an open splice buried under the cabinet without a junction box(code violation), but it was in a possible wet location(serious lack of common sense), a leaky sink, valve in a supply line, or disposal are common leaks. The disposal in my kitchen sink started leaking (internal seal went bad) which got the open spice wet, the paper in the Romex wet, causing the arcing against the wood of the cabinet carcass. The icing on the cake was that the electrical genius never connected the ground wires together, the incompetence was epic. I was pissed as my house could have burned down all because some POS did not want to take the time to run new piece of Romex from the breaker box when the piece they cut was too short or put the splice in a properly accessible junction box. I am putting the splice in a steel 2 gang box with a cover plate in a dry location two cabinets away from the sink, properly grounding the wires and box, and I am running 12/2 w/G UF-B out of the box to go under the sink and dishwasher, per code UF-B can be used in wet or dry locations within a home as well as direct ground burial.

What is the wire size of the grey wire? 14awg, 12awg, 10awg? It will say on the coating. Grey Romex just state that it is excepted to be buried underground. Is the heater 110 volt or 220 volt?

Yeah if you ran it yourself. You could use it for indoor or outdoor purposes. I have no Idea why it’s cheaper now🤷‍♂️. It use to be the same price or a bit more. It is harder to strip if you haven’t used it before.

Hi Phillip. Great video. I have a question. I need 10/3 for a mini-split. I went to Lowe's, and the grey was cheaper than the orange. Is there any reason I shouldn't just use the grey? Also, how you you tell 8/3 from 6/3 when both are black? It doesn't say on the outside.

[@PhillipBridgesReviews]

8/3 and 6/3 should have white printing on the wire saying the type of wire and the manufacture date. On the 10/3. If the grey is cheaper you can us it. It is for outdoor purposes. Technically, some inspectors frown upon using outdoor wire indoors. If you are the homeowner. Do what you think is best as they say.

does the footage from the source to the panel matter in choosing the right classification of choosing which to use enjoyed the video it was informative oh blue is used for.. dc may i ask

[@PhillipBridgesReviews]

Yes, there is always voltage drop. make sure you are not losing too many volts as you increase the length. So example: If I had an Air compressor that was 200 feet away from my panel and took 20 amps 12 volt to power. I would lose 12.67 volts and result at the end load would be 107.33 volts. Which is a 10% loss. Maximum allowed is 5%. I would have to increase the wire size from 12 gauge to 10 gauge to make up the voltage loss.

Hi I'd like to know if the 10 2 orange Romex needs to be put in conduit inside a metal building? I'm running it from main service panel to new RV 30 amp receptacle box. The run is approximately 30 feet. Square D breakers are used in main panel and I'm going to have a Square D breaker in the new 30 amp box as well. Thank ya for any help :-)

[@PhillipBridgesReviews]

Anything that is 7 ft. and below I would run conduit. Then slide the 10/2 through it. So if you run the 10/2 up and over the rafters. Stub a piece of pipe up past 7ft off the ground of were your outlet is going to be mounted. Slide the 10/2 down the pipe. Exposed walls you want to have it protected. I hope that helped you out.

[@ginnawitters-evans5156]

Thank ya Philip. It's going to run approximately 10 ft straight up wall from 30 amp box and across shop wall about 30 ft and approx 8 ft down into main panel.

[@LakeNipissing]

Being 12/2 it is likely aluminum, like in my house. Most homes built from 1966 to 1976 used aluminum wire for all branch circuits, because of the extremely high market price of copper at the time. Look for something like "ALCAN AL-FLEX 12/2 ALUMINUM WITH GROUND" printed on the jacket.

Can the UF-B romex be buried 12 inches if only using 120v? I read that it needs to be buried 24 inches, but if only using no more than 120v, it can be buried 12 inches... is that so?

[@PhillipBridgesReviews]

It can be at 12 inch. But must be 120 volt GFCI protected and not more than 20 amps. Also must come out of the ground in rigid or PVC when stubbing into a building. That being said, some towns do enforce the code that no matter what it must be down 24 inches. Check with local codes always to see what is enforced in your area.

Great video and information. I have a question. I noticed the a contractor put white Romex 14/2 for my water heater. My water heater does not state the amps, but has the watts for the elements, which is 3800 watts per each element (top and bottom) and the voltage is 240 on the tag. Doing the calculation for Watts= Amps x volts, which comes out to 15.8 amps. I also noticed the contractor placed a 30 Amp breaker. I believe he did both the breaker and Romex incorrectly. I believe he should have used 12/2 Romex (yellow) with a 20 amp breaker. Your thoughts??? Thanks

[@PhillipBridgesReviews]

Myself. I always do electric hot water tanks on 10/2 wire unless it’s a instant tank which I go by specs. Yes you are right. It is incorrectly done. It should be At least 12/2 and a 20 amp 2 pole breaker. The 30 amp could allow the 14/2 to melt the wire overtime when the elements are at peak. It is unsafe. Question. Does the white Romex say 14/2 on the side? Older 10/2 used to be white. I still have some laying around that I use on little things.
