foreign [Music] suitable wiring methods 110.8 the only wiring methods permitted to be installed in building occupancies or premises are those recognized by the NEC and and to make it simple we need to understand what is a wiring method so Brian why don't you take me to NFPA link and let's go to article let's go to chapter three and I'm wondering and Link what is chapter three I what is what are they title chapter chapter three as wiring methods and materials okay so chapter three is wiring methods and materials and if we take a look at my slide and we'll switch between the tools here but look at my Slide the only wiring methods which would be to be can be installed in a building or occupancies are those recognized by the code if we go to chapter three the general wiring methods right you know General requirements chapter one through four let's just really quickly go down Brian you got a great show right there let's go down we've got wiring methods well okay article 300 is kind of not really let's go back up right article 300 is not really a wiring method it's General right it's the stuff that we're going to be talking about the rest of this chapter okay and then 30 that's a new article over 1000 310 is conductors okay we got conductors we got cabinets and cut out boxes we got recept we got Outlets we got medium voltage we got armor cable uh flat cable assemblies another cable another cable another cable Cable cable what we're going to run into is chapter three has all the wiring methods the code says look whatever wiring methods that's permitted by the code is what you can do all right so we're like okay well like like okay I don't understand why you're spending all this time here well because of examples like this here and I think this probably be a great graphic to have in the book not as a support graphic to support that well clearly if the rule says only wire math is recognized by printed to be Co installed in buildings occupancies or premises and those recognized by the code clearly these fittings are not recognized it might be even electrical piping but the fittings are not recognized and that's not somebody's house that's on a commercial building yeah yeah it's not like some homeowner went to Home Depot and bought some parts that's in a commercial building but you know he did have a 90 here he had two of them going into the panel oh there's two okay and a little piece of flex yeah and the yes piece of black cared about safety put an art flash sticker on there hey oh there's an art flash label inside here that was the engineer that came by and did that where's the label we'll stick that puppy Engineers like there's nothing else I can do this is PVC okay yeah so let's go to the wiring method that's contained in a code for PBC so let's go to 352 and Brian let's look at 352. 6 which talks about the scope I mean it talks about PVC conduit Factory elbows and Associate fittings shall be listed so we were gonna we can make this a 110.10 110.8 code violation right here and we would also say that that violates 252.6 these fittings are not listed for that particular limit and one more violation what is it 300.15. what is 315 that fittings must be designed for the specific Raceway so Mario we need to get some of these and put this in a 315 maybe not the same one but we could use the same listen while we're writing them up we'll just do 110.12 and say that that's a sorry job and poor execution that's my favorite right there as long as we're on a roll here it's also 352.24 a hold on let's go there oh yeah yeah we're gonna file it up on this guy that's right what does that one say 24 is Ben's okay Ben's shall be made uh shall be so made that the conduit will not be damaged and the internal diameter of the conduit will not be effectively reduced field Bend shall be made only with identified bending equipment the radius of the curve to the center line of such bends shall not be less than that shown in table 2 chapter 9. click on that Brian let's see what the heck is he talking about there table two chapter nine is there a radius in it what is this let's see let's see yeah table two chapter nine right click on that this is what this is half inch you think probably have well something's happening some three quarters it looks like some three quarters are you in chapter nine table four you look like you're in four well maybe they didn't have the right link yeah the wrong way I have the wrong link well no radius right here chapter nine two Brady is a kind of Brian higher oh there it is okay half inch radius is going to be go a little further to the right expand table so if it's a half inch let's just say the radius is four inches right yeah so our plumbing 90 is definitely yeah all right so we can't work at that that was 352. 24a 24a okay just write them all up so they know you're really smart alrighty okay so suitable wire methods here's another Plumbing fitting right in the ground definitely looks like a weatherproof box yep I really don't like that graphic why that Bell box and the ground facing up with the screws what's wrong with that I'm sure it's not a violation but it is going to fill up with water and the splice is going to burn up so it goes I said I just said I didn't like the picture okay listen what you don't have a service department in your company so you're not thinking about your brothers and sisters after you do this installation because if you cared about your brothers and sisters you'd make sure you do it code compliant and if it burns up outside in the ground it doesn't really matter now you might burn the house because there have been cases of boxes and and wiring levels that's wiring outside and and and and betting material I replaced a forty thousand dollar generator because of some low volt lights a homeowner installed and caught all the Landscaping off yep yep so start thinking about your other people besides yourself
