Lab work

 

Date

  
    Multisim: Troubleshooting 1. Right click here to download the file.
Multisim: Troubleshooting 2. Right click here to download the file.
9-21 Troubleshooting a breaker box with five branches. (060921)
  1. Right click here to download the file for the circuit that has no faulty components. When asked whether to save or open the file, choose Save. After you've saved the file in My Documents, then click Open.
  2. Play around with the circuit to be sure you know how it's supposed to work.
  3. Right click here to download the file for the circuit that has a faulty component in each branch. (Follow the same procedure as in step 1 above.)
  4. Help each other out. OK to pair up with someone. Both people will get full credit.
9-26 Wiring a 3-phase furnace (060926). MS
9-26 Using an ohmmeter to find shorts in a parallel circuit. (060925). Right click here to get the file. MS
9-26 Parallel troubleshooting problem 1 (060925-1). Right click here to get the file. MS
9-26 Parallel troubleshooting problem 2 (060925-2). Right click here to get the file. MS
9-28 3-phase source, single-phase and 3-phase loads (060928-3). Right click here to get the file. MS
10-5 House wiring troubleshooting. Click here to get circuit 1. Click here to get circuit 2. Click here to get circuit 3.
10-24 Crimp RJ45 connectors.
11-2 Find code requirements for the items listed below. Then get into Nvu and type or paste a very brief description of what we need to do to satisfy these requirements for our solar electric project. Think in terms of describing these requirements to someone working under you--someone who needs just the facts. E-mail me the HTML file that Nvu produces. My e-mail address is bruce@mounttaylor.com . You will receive a percentage grade for the project, not just a check mark.
  • Battery enclosure
  • Battery interconnecting wire
  • Outdoor conduit carrying 120 VAC
  • Photovoltaic (PV) Ground fault protection
  • PV grounding
  • PV circuit breakers
  • PV disconnect switches
In addition to the printed code governing PV installations (a copy of which I gave you), there is an extensive article by John Wiley covering the code for PV systems. This article is on some of the computers in the lab. (It's too long to download from the Internet in a reasonable amount of time.) The file name for the article is PV-NEC-V1.3-Sept06.pdf , and you'll find it in the 115 folder in the My Documents section of the computer. If the article isn't there, ask me for a CD containing the article. Instead of reading all 144 pages, use the find icon (binoculars).
11-2 Make a three-view sketch showing all the components of our solar electric system, including very rough dimensions. (Percentage grade.)
11-2 Make a list of all the parts we'll need for our solar electric project, and then find part numbers and prices on the Internet. Suggested sources: www.electrical-supply.net , www.grainger.com . (Percentage grade.)
