In the case of three phase 120/208 it's a y connected bank which gives 120 volts to ground from any of the three legs and 208 between the phases .Simple on y to figure ,single phase voltage times the square root of 3 which is 1.73 . Electrical trivia 101 .
Ahhh jeeze Al, a refresher course from 6 or so years ago. That confounded house I've been sitting for has required this knowledge a lot. Between organizing the wiring to the panels and identifying circuits(9 panels total) and sorting out the fried controls to the elevator, it was kind of nice to play with some 3ph stuff instead of low voltage DC circuits.
In other news, I found out just how much they are gonna bust my bollocks in relation to my financial aid package. I'm limited to 5 specific classes, that I can spread over the next 2 semesters. I'm limited to BIO 101, Anatomy and Physiology 1 and 2, Microbiology, and Intro to Psychology, roughly 19 credit hours... so I'm looking at 12 this semester and 7 next semester. Now I've got to figure out what I'm going to do if I can't get into the online BIO 101 class.
If I can't, between A&P and BIO 101, and I can't find anyone to divy up the costs with, the lab instructor(same one for both classes), has specified out $400.00 in lab supplies, plus shipping. If I can take the BIO class online, I'm out a paltry $250.00 plus shipping for A&P, and it better be for 2 semester worth of supplies. It wouldn't be so bad, but A: this is separate of the college bookstore (IE can not be rolled into the tuiton), and B, isn't this what lab fees are for??? This is insult to injury when you factor the cost of the textbooks. :roll:
Shocked also that as the sling had not once been abused or heavily loaded and new seven months ago.
