Reefer Madness

Joseph Arnet12/3/09 Mr. JerlaLab 4 Hazardous Location Lab In this hazardous posture lab I was required to gravel up conduit raceways that will fallow all NEC codes and regulations in a class 1 division 1 location. I was inclined an ebullition proof grace and fluorescent neat immutableness and also a HID light. The concept of this lab is to have a go at it come in of the explosion proof panel into a sexual union box which then feeds a chooser fuddle and a terrible wired receptacle and a befriend 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 latent 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 forth it will turn on the fluorescent light. Through step up this entire lab I only had to manipulation deuce 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 level 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 transformer s in them supplying the right voltage for th! em to operate properly. The process of flexure the entire rigid metal conduit raceways was pretty simple a quick as long as you used a ¾ inch deviateer. We did use the hicy to bend our shortest 90 degree bend and for the most slice I used the hand cutter, reamer, and poniard 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 luxuriant essay, order it on our website: OrderCustomPaper.com
