Bonus point for safety: when cutting the jacketing, just cut the first inch or so, and PULL the jacketing back about six inches. Don't use a knife for the full six inches. If you insist on using a knife, inspect the conductor visually and by touch to make sure the individual jackets are 100% intact. Here's why: If you cut the full six inches of the jacketing with a sharp knife, you risk knicking/cutting the jacketing around each individual conductors. Knicked and exposed wire is unsafe. Higher resistance, more heat under load, and a chance of arcing between two exposed conductors.
Thanks for taking the time and effort to make this video. Even while just holding your camera, you were still able to inform, and I learned what the difference between 2 and 3 was.
Also of note is that the color-coding system is pretty recent. If it's pre-2000s (as in my home) it's usually all white (unless it's a high-gauge wire, usually black or gray, as in a service entrance cable).
Good video, funny camera work. :P It did get me thinking about 12/3 wiring for ceiling fans. We should rewire the house someday because we have old aluminum wiring. It can be properly adapted for safety, but if we needed to do a full rewire, it would be smart to run 12/3 cable to the ceiling fan so we could operate power to the fun and light separately. Yeah, 14/3 would be fine, but since this house has always used 12 gauge wire for 20 amp lines, I'd just stick to that. Although, code probably forces 12 gauge wire in between switch and light on a 20 amp line in case something wrong happens. Consistency is a good policy.
The NEC even calls out how to do this in article 314.16, tables314,16(A) and 314.16(B) 314.16(A) lists common box sizes and maximum amount of conductors allowed. For example, a 1900 box that is 1-1/2" deep can have 14 no.14, 13 no.12s, and 11 no.10 wires. To convert AWG to cubic inches, 14 is 2cu in. 12 is 2.25, 10 is 2.5 per 314.16(B). Any devices are counted as 2 of the largest size wire in box, as connected to device, a double allowance. The grounds are counted as ONE of the largest wires present. Cable clamps, if internal, are counted, as are fixture hickeys and support fittings.
Sam ! Thanks ! I know nothing , nothing about electricity and I am starting to learn YOU are the man and keep it simple for me It was great Guys were trying to explain wires to me but your video and calm clear manner was the best yet Kirby Sides
Do they ever make stranded Romax? Also is the ground wire always the same gauge as the other conductors? So is a 10/2 Romax cable have a 10 gauge ground as well?
I was watching romex 101 particularly to see hou you cut romex and how you cut open the sheathing. is the a trick to aviod nicking the line wiresunder the sheath.
I have what I would call a good Question- But for you an expert electrician it’s probably simple I’m tapping Ac current off the back of my car alternator off the Stator the copper wire mesh under the casing to use the Romax wire I can use the case is the ground positive is tap straight to the copper wire which produces the purest sine wave what do I do with a neutral ? “ Please “ this is a DYI home generator & it produces 2,000 Watts at about 1,900 RPM ! I have it recorded !
what kind of wiring should i be using for putting outlet in my trailer that im trying to convert into a camper. just 15 amp outlets and one lights.would a 12 -2 wiring work.?
You cannot call this "Romex 101" and exclude the history: Romex was invented by Rome Cable Company in Rome, NY. It is now a trademark belonging to Southwire.
Richard Neal Not legally! Two reasons, not allowed in more than 6 feet of conduit because of heat, and not allowed below grade because it is not rated to be in water. Pvc fills up with water even if glued. Use spooled conductors, not jacketed cables. Hope this helps you.
Anyone can reply to my question. I was drilling into a wall to run some camera cable and nicked a Romex number 12 cable enough to trip the breaker. There doesn't appear to be any cut to the wire itself but it definitely took off the sheathing. It's a small Nick where the drill hit it but I don't see any cuts to the wire at all. Would this wire need to be replaced in entirety? Or can it just be electrical taped to recover the exposed wire. The damaged area is less than a half an inch
I'd opt for replacement between the places that segment of the circuit goes, on the basis that it could arc and start a fire in the future. In times where ONLY the jacket tears, as it can while first installing it, a wrap of white, yellow, or orange tape (match the color of the jacket) is perfectly acceptable. Note that you do not have to follow the same path exactly,especially if it's easier to fish cable between points, up walls and across attics, under floors, etc. Other things I've been known to do, is run pipe between 2 metal boxes on different floors and pull THHN between these points to facilitate future circuits. Or run 3 and 4-wire MC cable where I'm fishing it in walls.
FAMILY URIAS I hope you did not use romex outdoors. It is for indoor use only! UF is exterior rated. Size is based on load in amps for conductors and over current protection(circuit breaker)
Bobby Medina would not recommend this. 14/2 will only handle 15 amps whereas the 12 will handle 20 amps. If someone were to see the 12/2 and think the circuit could handle 20 amps not knowing there was 14 gauge wiring down the line this could lead to problems. Best to keep with the 12/2 for the entirity of the circuit
Can i use romex wires for a solar set up in a house? i googled this but there wasnt a yes or a no, just got a bunch of stuff that the wire is generally used for. Nothing specifying anything. I do understand its use for residential.
Yeah I don't see a problem with that. You'll just want to make sure it's sized properly, not subject to any physical damage, and I wouldn't suggest running romex outdoors without being in a conduit or raceway of some type.
NEC 690.31 backs this up, though commonly, types XHHW, and UF are used outdoors with success. NEC article 340.10(2) specifically allows UF to be used this way, in PV/Solar systems, in accordance with NEC 690.31. Note that NM-B (Romex) cannot be ran in wet locations, buried, or fished inside exterior masonry wall voids, nor embedded in cement/mortar/grout/plaster, as called out in article 334.12 (A), 334.12(B)
QUESTION SIR....IN MY 10 BY 20 MAN CAVE...I WIRED MY BUILDING WITH 12/2 ROMEX...CAN I USE 12/2 UF FROM MY MAIN PANEL IN HOME?AND HOOK TO 20 AMP SINGLE POLE BREAKER? 20 AMP IS ALL THAT IS LEFT ON MY MAIN BOX
No need to repeat things (like the gauge numbers) over and over and over. (We can skip back easily if we need to). Another suggestion: Steady that camera! (camera person, tripod, etc.).
That's also not permitted, in the open, as all splices have to be made in boxes. With UF cable, this is the only way to do it outdoors, whenever a listed/approved splice kit is used. Usually, I'll turn the ends up into a 6x6 plastic junction box for accessibility, and splice with dryconns, however, these are listed for direct burial.
@@Nick-bh1fy Is a 240v outlet for a welder 161 amps at 35% duty cycle, 4ft drop from the main 200 amp breaker, to short of a wire run? I'm using a 50 amp breaker and 6/2 romex
If it ain't round I turn it down not quite sure what Youre saying but installation seems correct to me assuming the run is a couple feet like u said should work fine
@@Nick-bh1fy I didn't know if my 240v outlet was too close to the main breaker panel as far as code goes. I'm only a 3ft drop down through the wall from breaker box to outlet.
If it ain't round I turn it down I wouldn’t necessarily worry about being too close unless sparks will cause an issue for u otherwise you should be good to go
At 2:40 mins you used razor knife and cut in a motion towards you. To all that are not handy please use a hook blade and always cut away. I know you were not showing how to properly open romex but people get bad ideas when watching.
Michael Young ha! That's funny... I recall being in direct competition, or having to gain your approval with being competent in this trade. I made a comment about Romex being garbage, which it is... it's only practical use is for temp power on a job site, if that. In this city, where we lay pipe, like good Electricians do... Chicago code even requires that temp services be piped, unless it's for temporary lighting. Now I could give you the formula for a "3 Bend Saddle..." I could give you the formula for a, 4 bend saddle... but, not be an asshole on purpose, which as you can see I fairly good at, no lessons for free son. I don't work for you, nor do I get any checks signed by you. Until the day cometh, where in I need your approval... which will require you to be paying me... you can fuck off. I not in this trade to seek you or any other Electrician's approval. In fact we are all competitors, and I will not recite code, formulas or any other secrets to you. Suffice it to say that I've bent so much fucking pipe, roughed in enough shit, that I don't need a formula do a three bend, 4 bend... offset, gooseneck, 90, 90 with a kick, back to back 90, or an Z. You fucking CZcamsrs have something stupid to say Everytime somebody attacks something you like... like fucking Romex. Fuck Romex. That shit causes more problems than the money you save on pipe. You pipe a house right once, if there is ever a problem, you just pull new wire. And if you, "know what you're doing.." 😂😂😂 in the first fucking place...there should be no problems. There is your school lesson for the day... oh and one more great thing about laying pipe, bitches love it... and you actually feel like you did something, instead of like a low voltage guy... running a bunch of rg6 and cat6 around the house, stapling everything like a bunch of sissies. And one last thing... fuck you Savor, come mierda Marion, pendejo. Estupido. Yes man. Good reply... shut the fuck up! Dumb ass Romex Electricians piss me the fuck off!!!😠😠😠😠 Something goes wrong you got cut a fuck ton of holes in the house... using gay ass plastic smurf boxes. 😂😂😂😂 You MF's are a joke!!

Put the black tape on the white conductor when using it as a hot? Wiring a three way switch.
Do they ever make stranded Romax? Also is the ground wire always the same gauge as the other conductors? So is a 10/2 Romax cable have a 10 gauge ground as well?
Informative AND Entertaining. Thanks!
Just be careful cutting sheathing the way it is shown here as razor may compromise wire insulation.
Thanks 🙏

Have a cup of coffee. Sloooow video.
at 3:00 isn't that called a 12 2 grounded meaning the 2 wires plus the ground?
Dan Hard 12/2Wg. W stands for "with" g stands for "ground"
can i splice 12 2 wiew into 142 wire?
Yes, if the breaker on the circuit is 15 amps. If the circuit is protected by a 20 amp breaker the wire could be overloaded.

Nice catch.. ? Are the color in NEC code ?
It's a NEMA standard, the NEC is silent on the matter. Makes inspections go easier, as they can look at color, and see it's right.
