Reefer Madness

Joseph Arnet12/3/09 Mr. JerlaLab 4 Hazardous Location Lab In this hazardous position lab I was required to correct up conduit raceways that will fallow all NEC codes and regulations in a class 1 division 1 location. I was inclined an gush proof grace and fluorescent get down immutableness and also a HID lightly. The concept of this lab is to write off come in of the outburst proof panel into a sexual union box which then feeds a selector throw 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 potentiality across it unless someone turns of the surf for it set(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 left(a) it will turn on the fluorescent light. Through out this entire lab I only had to manipulation ii explosion proof pestle offs. The first one is regain 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 crosswise 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. both the HID and fluorescent light have step up transformers in them supplying the right voltage for them to operate properly. The process of curvatureing the entire rigid metal conduit raceways was pretty simple a quick as long as you used a ¾ inch bender. We did use the hicy to bend our shortest 90 degree bend and for the most slice I used the hand cutter, reamer, and threader for my conduit raceways. The NEC codes that I us ed during the installation of this hazardous! location lab are as...If you want to get a total essay, order it on our website: OrderCustomPaper.com
