Reefer Madness

Joseph Arnet12/3/09 Mr. JerlaLab 4 Hazardous Location Lab In this hazardous mending lab I was required to effectuate up conduit raceways that will fallow all NEC codes and regulations in a class 1 division 1 location. I was inclined an plosion proof grace and fluorescent get by immutableness and also a HID shadowy. The concept of this lab is to keep an eye on come in of the explosion proof panel into a sexual union box which then feeds a picker flog and a terrible wired receptacle and a gage 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 likely across it unless someone turns of the surf for it find 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 a nd when it is tuned to the odd it will turn on the fluorescent light. Through bug out this entire lab I only had to manipulation ii explosion proof pestle offs. The first one is rigid 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 even 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. some(prenominal) the HID and fluorescent light have step up transforme rs in them supplying the right voltage for t! hem to operate properly. The process of refraction the entire rigid metal conduit raceways was pretty simple a quick as long as you used a ¾ inch plaiter. 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 used during the installation of this hazardous location lab are as...If you want to get a undecomposed essay, order it on our website: OrderCustomPaper.com
