Joseph Arnet12/3/09 Mr. JerlaLab 4 Hazardous Location Lab In this hazardous office lab I was required to dress up conduit raceways that will fallow all NEC codes and regulations in a class 1 division 1 location. I was inclined an volley proof grace and fluorescent escape immutableness and also a HID crystalise. The concept of this lab is to coiffure come in of the salvo proof panel into a sexual union box which then feeds a selector electric switch and a terrible wired receptacle and a irregular junction box. The second junction box then feeds the HID light and the fluorescent light secureness. The gruelling wired receptacle is wired on its own separate hitch and has a constant 120VAC capability across it unless someone turns of the surf for it fit(p) on the explosion proof panel. The HID and fluorescent fixture ar wired to a separate breaker also, this rope is controlled by the selector switch. When the switch is turned to the refine it will turn on the HID and when it is tuned to the go away it will turn on the fluorescent light. Through break this entire lab I only had to manipulation two explosion proof pestle offs. The first one is fit(p) on the receptacles primed(p) surface conduit raceway and the second one is located on the steep run leading to the selector switch. I did not besides place one on the naiant conduit run advance out of the panel because inside the explosion proof panel there is a factory do seals separating the make or break contacts from the upper division of the panel. some(prenominal) the HID and fluorescent light have step up transformers in them supplying the right voltage for them to operate properly. The process of plication the entire rigid metal conduit raceways was pretty simple a quick as long as you used a ¾ inch sheep pener. We did use the hicy to bend our shortest 90 degree bend and for the most slice I used the hand cutter, reamer, and bodkin for my conduit raceways. The NEC codes that I used during the installatio! n of this hazardous location lab are as...If you want to get a adequate essay, order it on our website: OrderCustomPaper.com
