Reefer Madness

Joseph Arnet12/3/09 Mr. JerlaLab 4 Hazardous Location Lab In this hazardous status lab I was required to institutionalise up conduit raceways that will fallow all NEC codes and regulations in a class 1 division 1 location. I was inclined an turn outburst proof grace and fluorescent escape immutableness and also a HID light. The concept of this lab is to pay off come in of the burst proof panel into a sexual union box which then feeds a selector substitution switch and a terrible wired receptacle and a s 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 primed(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 i t will turn on the HID and when it is tuned to the leftfield it will turn on the fluorescent light. Through out this entire lab I only had to manipulation twain 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 plain conduit run advance out of the panel because inside the explosion proof panel there is a factory make seals separating the make or break contacts from the upper division of the panel. both the HID and fluorescent light have s tep up transformers in them supplying the ri! ght voltage for them to operate properly. The process of crease the entire rigid metal conduit raceways was pretty simple a quick as long as you used a ¾ inch reverseer. 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 installation of this hazardous location lab are as...If you want to get a wide of the mark essay, order it on our website: OrderCustomPaper.com
