    Psych Minors Welcome

    I am wondering if I should be having a candid and open conversation with one of the guys at my company. (A midsized MEP/FP firm) I have been working here for just over a year, am 2 years out of college. At my review recently, I was expecting some big 'something' to come from it. I wasn't...

    Reactor Design and Fault Current Levels for a Chiller

    This was an interesting issue I ran into while doing a fault study for a hospital. We turned out to be about 3kA over the 35kA AIC rating of an existing chiller. This rating was mostly constricted by a couple parts within the starter , (CB and contactor) that were only rated at 35kA. I was...

    What is the value of a Benefits plan?

    I am in the boat of not being sure how important a benefits plan is, how much the things are going to cost me if I cannot get one in my work, and if I need to be searching for a job where benefits are present. I am fresh out of school and am now 'technically' working as an independent...

    In-Circuit Testing of a Diode

    Hello, I am trying to test a diode on a PCB for work in forensics, concerning a product failure that caused some batteries to explode. I have posted on this topic before but I have more specific questions this time. Does anyone here have any experience with in-circuit testing? I have...

    academia - associate vs assistant vs emeritus

    The academia totem pole seems like it involves a lot of politicking and un-even-handed methods for getting on top. That's one of the many reasons that I don't want to get involved with the field. But looking through my school I just recently graduated from, I see that there are a number of...

    Placing a fan/fan motor in vacuum..

    I am wondering what happens when you place a fan motor or air pump in a situation where it is trying continually to move air from a lower pressure to a higher pressure, ie, the exhaust fan on a microwave. Doesn't this cause problems for the motor? In terms of load, would this be a higher or...

    Another NEC quiz - Flourescent lighting wiring

    This structure was built in 1960, keep in mind, so if anyone knows a great deal about how long the NEC has been around or on its standards way back when, feel free to chime in. What was done is: A 277V flourescent light fixture has 2 other lights on the same branch controlled by one switch, and...

    Where to solder on a solar cell

    I am working on a home project to build a temperature controlled, solar powered, fan for a rabbit hutch at a friend's house. I went to radio shack to just buy one solar cell to mess around with and familiarize myself with the things. I am looking forward to getting a better set of them so I...

    Taping conductors together?

    Are you allowed to carefully tape conductors (bare) together to establish a connection in a control panel or would the NEC approve of something like this?

    A/V multiplexor - Design Question

    Maybe something like this already exists, but I am trying to help my grandfather out in hooking up his brand new DVD player and the VCR to the TV at the same time. The inputs in the backs of the devices don't allow for it. And I realize that we might be able to just return the player, but I...

    Battery/Product Failure, question

    Hello, This is my first post, but it definitely seems like this board is a great resource. I just graduated from a good engineering school with a degree in EE, and am now getting into forensics. I'm pretty green but am already on a big case involving a certain company and a product of theirs...

    NEC issues - Garden Hose as conduit?

    Is it NEC-acceptable to use common garden hose as electrical conduit? Also, if anyone is a electrical inspector, and has access to good resources on commonly-made NEC violations, or even better, wiring practices that are dangerous and prone to starting fires, please link me up, Scotty! Jim...
