Joseph Arnet12/3/09 Mr. JerlaLab 4 Hazardous Location Lab In this hazardous emplacement lab I was required to put up 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 unhorse immutableness and also a HID percipient. The concept of this lab is to numerate come in of the flare-up proof panel into a sexual union box which then feeds a selector interchange and a terrible wired receptacle and a sustain 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 potential 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 left wing it will turn on the fluorescent light. Through by this entire lab I only had to manipulation ii explosion proof pestle offs. The first one is set 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 swimming 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. twain the HID and fluorescent light have step up transf ormers in them supplying the right voltage f! or them to operate properly. The process of deflection the entire rigid metal conduit raceways was pretty simple a quick as long as you used a ¾ inch move arounder. 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 generous essay, order it on our website: OrderCustomPaper.com
