Its not a 3/8" flex. Its a 3 wire MC cable, perfectly up to code. Code has been my life for over 30yrs. I call the NEC code book the bible. Have every edition since 1980 to date.
Woah, what about Romex to a light fixture. This would be grandfathered in now, but for 12/2 or 14/2 the HOT to the switch is the WHITE wire, and the switch leg back to the fixture (luminary) is the BLACK wire. Some local jurisdictions will still allow that. Some jurisdictions are still using pre-1980s NEC. They are generally small rural areas who do not want to train anyone, and don't have the money to do it anyway. One jurisdiction had their fire marshal doing electrical inspections, and she just had it dropped in her lap without notice. I helped as much as I could, showing her what most inspectors look for the most often, wire fill, wire ampacity, derating, proper overprotection, GFCI use, etc.
I like how the NEC code book is lighted, and with book tabs great lay out, The electrical work look dangerous, crowded conductors in panels, improper grounds, lots and lots of code violations period.
I think your comment on 200.7(A) was not specific enough. 200.7(C) says you can put live voltage on white-colored wires, if you mark them at the terminations with electrical tape. Your video isn't high enough definition to see, but I do see some marked wires. Were these marked?
that quad outlet box was bonded per the device rated ground yoke and 8\32 screws that fasten the raised cover. aaaand that box is not equipment fastened in place. it is a outlet box with 2 duplex receptacles. lastly I'd bet that gutter was OK in size. add it all up. the code isnt at tough as most think.
At 4:49 where you mention the 3/8" flex, I'm pretty sure that's MC cable. The plastic ribbon you can see coming out of it with the wires is a dead give away. They didn't pull those wires but rather it comes that way as a cable assembly.
Definitely an MC/AC cable assembly. Perfectly legal in that installation. The electrician could have made the connections using a wire nut and a green ground screw in the threaded hole provided in the box by the manufacturer, and used a decent MC/AC connector. He didn't.
are you saying that a 12/3 mc cable can not be used to power a 240 volt device because it has a white wire ? I m pretty sure that if you do use the white as a hot you have to identify it with a black or hot color tape , then its acceptable
exhibit 250.56 and 250.58 state that a self grounding spring grounding clio receptacle with 2 mechanical threads enagged or a non grounding receptacle with one insulating washer removed and 2 mechanical threads engaged does not require grounding the box.
Municipalities get to inspect themselves. City of Phoenix has some of the most atrocious wiring on the planet. One building had baloney all over the rooftop, penetrating the roof and running down into the walls. Another panel had been moved with 42 circuits in one undersized conduit. The drywall was turning brown and had SMOKE coming off of it. Remember derating?
wow! Looks like they were going for a real life saw movie there. "either you stick your hand in that gutter to turn off the time clock, or both you and your girlfriend get electrocuted on the wet floor." great video, looks like you're an organized and smart future electrician. I hope you're still in the trade.
at 3:40 when you talk about not connecting the green ground to the box, isn't the ground connection on the outlets themselves part of the mounting bracket which creates the ground bond?
1957mrbill no the box itself must be grounded, along with the receptacles. It's kind of funny because you can see the little "bubble" in the back of the box that's meant for a ground screw. Guy must've not had one on him. A lot of old school guys did stuff like what you see in the picture, and to be honest it's a perfectly good ground connection, it's just not legal. I suppose it would be sort of exposed to being bumped into but not very much. If he was out of ground screws he would've been better off just putting a machine screw into the back of the box meant for the ground screw and calling it a day. AND FFS TAPE UP YOUR OUTLETS IN METAL BOXES.
wait, on your two gang outlet box the center screw that they used is bonded to the ground on the outlet isn't it? Either way they should have put the other 4 screws in rather than trying to save a minute
My dad smoked a saber saw by plugging it into a 120v outlet fed with 240v. Ran at double speed, shot out sparks, and gave up the ghost in about 10 seconds.
Quad box, gen purp. Or residential ap. The yolks of the recep. Will at least provide a ground for dummies but they didn't even bolt the device to the cover, only plate position screw were used....wow...no concept of ground whatsoever.
The box will be grounded by the connection between the box and the cover. However, especially with an outlet, where the action of inserting and removing the cord to and from the outlets could loosen the connection, cause the wires to chafe and cause a live condition on the box itself You'd certainly be better of being in compliance with article 250. When in doubt- ground everything separately, you really can't go wrong.
Even you are the good and experience contractors to do those electrical works, and you must get the quality materials such as cables which are "made in US."
Come down to the fact that the more money you have the cheaper / tighter and lazier you are. Businesses are the worst at violating codes. They want max production with minimal cost.
quick question can you add more than one hot to a 120v 15 amp breaker for an extra outlet with out problems at the breaker. I have no more room to add additional breakers in my box and need to add an outlet. i check the circuit and there is only 5 outlets connected to it. i don't want to splice in and add a junction box cuz the wire is all ready ran to the breaker box just not hooked up.
no, you cannot have more than one wire on a breaker at one time. You CAN however use tandem breakers which will give you two breakers for the space of one, and is only on a single leg.
They do have Double Tap breakers for exception use only, but it would be better to upgrade the main, or other safe option to wire in sub panel if half size >>tandem breaker
you sure can if its rated for it. some breakers are rated for 2 equal size wires. and should also be both solid or stranded. don't listen to every code nazi.
Holy crap some of the stuff was just lazy workmanship but having energized male plugs just hanging out and on top of that being switched on automatically that's one of the absolute dumbest most dangerous things I've ever seen. How do you work with something like that just make a wrong move and you get poped
MC cable is routinely used in commercial applications, it's not illegal to use. The fact that you didn't know that and what it was you were talking about makes this whole video suspect.
I just saw this video and just saw your comment and agree with you fully!! Also the thing I personally noticed that was suspect is he also says you can't put power through a white wire, that is not accurate you can use a white wire for power HOWEVER it can't be white throughout phase/indicator tape on various spots of said wire is acceptable if it is not being used as the neutral! He also said the white wire can be used as a ground which is also not accurate UNLESS it's phase taped green! So the way I see it he's got a lot of great information because those relays in the beginning were absolutely too tight in that gutter and did not allow for legal safe heat dissipation but he definitely got at least a couple things wrong here!!
Right!! Electric utility has their own rules - "code" does not affect them (this according to power company service person). So... Not being an electrician, how is these crappy electrical jobs exist? Is this work being done without a permit/inspection? Or are there some sh*tty third-rate, or worse, electricians out there??
I have seen a lot of this so called electrician do all crap work I never used a book but I know when it’s wrong the ones who goes by the book in most cases do shit work I had to deal with a lot of them lol.
You talk from code violation only but why you not say that you talk about the U.S.A. laws - one of the lowest power and electric laws how I see till yet! I can only cry OMG!
The 240 V on the 110 V outlets is the stuff of nightmares
Its not a 3/8" flex. Its a 3 wire MC cable, perfectly up to code. Code has been my life for over 30yrs. I call the NEC code book the bible. Have every edition since 1980 to date.
Great video. Really like that you show and cite the code violation. Looking forward to seeing more videos.

I love the Constantia wire atop the pole around the service wiring! That bad out there in LA?

I was thinking of phase taping the neutral white wire.
that quad outlet box was bonded per the device rated ground yoke and 8\32 screws that fasten the raised cover. aaaand that box is not equipment fastened in place. it is a outlet box with 2 duplex receptacles. lastly I'd bet that gutter was OK in size. add it all up. the code isnt at tough as most think.
Wonder what kind of equipment uses a receptacle instead of a regular cord set?
At 4:49 where you mention the 3/8" flex, I'm pretty sure that's MC cable. The plastic ribbon you can see coming out of it with the wires is a dead give away. They didn't pull those wires but rather it comes that way as a cable assembly.
I was just scrolling down to day that.
Definitely an MC/AC cable assembly. Perfectly legal in that installation. The electrician could have made the connections using a wire nut and a green ground screw in the threaded hole provided in the box by the manufacturer, and used a decent MC/AC connector. He didn't.
This was 100% a cannabis grow facility, surprised they cheaped out on the electrical work.
Jon Bettinger I bribed my OSHA inspector with some weed one time.
Hahahahahahahahahahahahahaha 4:20 tho omg!

Forget horror movies. This is the real scary shit.

Yeah , I don't think Grow-op people care too much about codes or standard. That's actually a good job vs some I've seen.
receptacles in metal boxes also need to be supported by the top and bottom screws beside the middle screw of the receptacle.
They doing demo removed scrussss
Typical LA style. Craftsmanship is almost non existent over there.
wow! Looks like they were going for a real life saw movie there. "either you stick your hand in that gutter to turn off the time clock, or both you and your girlfriend get electrocuted on the wet floor."

"What they were manufacturing here involved a lot of water."
Marijuana?
Good stuff man. Almost could hire you as a consultant. Might be something to look into doing!
5:07 that's not flex, that's mc. it through a 1/2-3/4 concentric knockout and the 3/4 knockout is in the process of busting out.
That's the SKID ROW area in DTLA.....
This was HORRIFIC!! :O
How could any building be run this way??
Whoever did this work were not electricians...... it's that simple !
Did you see the pipe fitting under the panel at 7:02 LOL I think its facing the wall
My dad smoked a saber saw by plugging it into a 120v outlet fed with 240v. Ran at double speed, shot out sparks, and gave up the ghost in about 10 seconds.
bamaslamma1003 why did he give up the ghost? Is he not a ghost type?
You are a robot aaaeeeyyy
Thank you so much for your information you’re the best 👌
Quad box, gen purp. Or residential ap. The yolks of the recep. Will at least provide a ground for dummies but they didn't even bolt the device to the cover, only plate position screw were used....wow...no concept of ground whatsoever.
4:20 don’t get high on your own supply!
Paying attention in code class.
6° of seperation and I' m not gay!
Gladys Ave, between 6th and 7th,
Seafood District, DTLA?
if self grounded outlets are used is it safe to pigtail green wires with wirenut and go to outlet it will ground the box

well informed,
6:40 that's terrifying
I wish you could see the house I used to live in when I lived in Baltimore. You would shit yourself when you see how it was wired.
Come down to the fact that the more money you have the cheaper / tighter and lazier you are. Businesses are the worst at violating codes. They want max production with minimal cost.
very informative
what countries even have electrical code?
Frightening that there were so many violations in a *commercial* setting. I always thought they were way more strict about that stuff.
Good point. I have actually seen someone growing it but in their back yard lol.
quick question can you add more than one hot to a 120v 15 amp breaker for an extra outlet with out problems at the breaker. I have no more room to add additional breakers in my box and need to add an outlet. i check the circuit and there is only 5 outlets connected to it. i don't want to splice in and add a junction box cuz the wire is all ready ran to the breaker box just not hooked up.

sure what is the name of book is available inline
Was that actually flex or was it MC ?
Farmer Dave mc..u can see the wrapping on the wire. I dnt see how its illegal to use besides the connector being out
@ 4:10 the box was grounded by the foil on the foam😉
The first violation is the way you spelled it
P.s. notice the over indentation of most of the stripped wires shown. Smh.
aye right , vilolations , a very real disease
Holy crap some of the stuff was just lazy workmanship but having energized male plugs just hanging out and on top of that being switched on automatically that's one of the absolute dumbest most dangerous things I've ever seen.

Good lord....laziness i dont think is the word...how aboout downright ignorate and not carrying!

I fell asleep at 4:20
i am "only" a pc-guy, but even i can see it´s shit. i like how us-sockets look like they know what will happen to them before it happens^^
Dwp here is department of work and pensions. 😂
This was a cannabis grow facility
Great video!
studied @lattc!
Right!! Electric utility has their own rules - "code" does not affect them (this according to power company service person).
So...
Not being an electrician, how is these crappy electrical jobs exist? Is this work being done without a permit/inspection? Or are there some sh*tty third-rate, or worse, electricians out there??
Wow!
Vilolations....
8:34 think your wrong need to re check those plugs.
Oh so scary
Nothing wrong here it worked fine until you look the code
wtf sloppy work
I have seen a lot of this so called electrician do all crap work I never used a book but I know when it’s wrong the ones who goes by the book in most cases do shit work I had to deal with a lot of them lol.
Rudy Bharatt no the ones who don't follow code are the literal hacks of the trade lol
You talk from code violation only but why you not say that you talk about the U.S.A. laws - one of the lowest power and electric laws how I see till yet! I can only cry OMG!
Try to learn to speak
