Electrical drawings Instructor In the last video,I introduced to you to the M Sheetsthat represented the Mechanical drawings on this project. And I told you that we sometimesalso refer to the mechanical drawingsas the HVAC drawings. Now, we also sometimes refer to themas being part of the MEP drawings. And the reason we refer to them as MEPis were talking about Mechanical, Electrical,and Plumbing drawings. The reason that we sometimes group these together like thatis that most often theyre all designed and drawn bya single MEP consultant.

A professional grade CAD software that allows you to design electrical circuits for installations and m. What I want to take a look at now in this videois the E sheets in our group of MEP drawings. And again, we see that list here,and Im going to use our hyperlinked index sheetand jump straight to the first one, Sheet E 0. So first, notice again that our consultant,up here in the title block,is the same as it was on our mechanical drawings,and thats going to be the same on our plumbing drawings, too. Flac S Canada. We have a single MEP consultant on this project. Next, notice that also similar to the mechanical drawingstheres still quite a few symbols and abbreviationsgiven to us here in the legends on the first page. Although its a little shorter,we still have a pretty long list of abbreviationsand a pretty long list of symbolsnoted here in the legend. Everything from fansand motors that mightbe shown on the electrical drawings. Now, also notice over here, I have whats calleda Lighting Fixture Schedule. And Im going to come back and explain schedules,and how we use those, a little bit later in another video. So, for now, though, lets concentrate onsome of these symbols in this legend. So if I zoom in,youll see here, Im going to just circle this,you see here that we have a symbol that saysthis indicates the installation of a telephone,or a data outlet. But again, were in the electrical drawings. This is one of those things that,depending on how complex the project,I might lump things like telephone and data,heres the TV outlet,all into a single drawing, or a single set of drawings,that Im going to call the electrical drawings. But as the project becomes more complex,I might have a separate set of drawings,one for just electrical, and one for just, for instance,lighting, or another just for telephone,and maybe another one even just for dataif theres a lot of data wiring in the project. Just depends on how complex the project is. For this project, all of those things,electrical, telephone, TV, data,theyre all included here in our electrical drawings. So, lets jump to the next page in our electrical drawingsand discuss some of the things that these drawings show us. Download Wireshark For Kali Linux Android. Im going to zoom in. Lets look atthe basement floor plan here. Take a look, youll notice thatthis is the electrical floor plan for the basement,and specifically,this is the lighting plan for the basement. So, all of these circles, if we went back to our first sheetand looked at what S2 meant,it would tell us that these are all lights,and you can see how these lights are all wired up. What I also want you to notice on this page is that,just showing kind of a broad arc between the lights. Quickly generate PID schematics in AutoCAD and AutoCAD LT with this easy to use symbols library. All symbols conform to specification ANSIISA 5. Autocad Electrical How To Draw Electrical Schematic' title='Autocad Electrical How To Draw Electrical Schematic' />So, we want the lights to be located in a precise location,but the routing of the wiringdoesnt necessarily follow this exact arc. What theyre showing us on this drawingis how the electrical designerwants these lights wired together. New Maps Warcraft 3. Theres going to be a little discretion leftto the electrician on the projectas to how they route these wires through the floor,or through the ceiling. Lets go ahead and jump to the next pageand look at another view. So, now were on the first floorand looking at the lighting. And again,youll seewhat the electrical designer is really trying to show usis their intent on how these lightsare to be wired together. These two are to connect inside this fixture,that and this one connect inside this fixture,before they go here, and we see in Note 1,and the Note 1 tells us that thats a home run. A home run, when were talking about electrical wiring,meansthats the point at whichall of these wires are going to go back toour circuit breaker orour control panel. Now, if this weresomething where we desired morecontrol over each outlet or each light,like maybe a hospital or a hotel,each one of these fixtures might home rundirectly to the panel. Thats a decision that is left up to the designer,and so, we use these drawingsto figure out the designers intenton how these things are wired together,and where they end up home runningand going back to the control panel. So, lets click throughand look at a few more pieces of information. You can see,just like the mechanical drawings,we start to get a lot of information hereand a lot more symbols,so now were starting to see things like electrical outlets,and if we looked around here, we could find our TV outlets,and were going to start to see some of our dataand telephone outlets. A lot of information here thatthe electrician or the data installeris going to need to interpret on these drawings. Now, before we leave these drawings, though, I want to skip toone of the last pages in our electrical set of drawings,which is the electrical details,and well just take a look at this one that saysits the voice and data riser detail. And youll see here that it says that theres no scale. This is not to scale. This particular detail is often referred toas a one line drawing. The intent of this one line drawing is to show ushow each one of thesefixtures attaches to,in this case, the riser,or the area where all this wiring home runs to. So, its just trying to show us thatall of the data connections in the kitchenhome run and go at the bottom location on this riser. The next location up belongs to the office. The next location up belongs to the living room. So, in this case, and again, weveoften times refer to this as a one line drawing,and that just means that this detailis not at all showing us how the wires routethrough the building,its just showing us how theyre groupedand how they connect where they terminate. Thats going to end our discussion on the electrical drawings. Again, just keeping in mine, most of the timethe only person thats going to use this drawingis the electrician,or the company thats installing the data connections. Stay with me, and lets move to our last type of drawingin our group of MEP drawings,and well again, look at some similaritiesin how these convey information.
