So,
I’ve been studying about an hour or two every day and 12 to 16 hours on the weekends for a month now. I have completely reviewed everything I need to know for the power section (second half = 4 hours) of my test. I took the second half of a practice test the last couple day. I totally failed. I now understand everything that they want. I keep getting tricked by these little catches. Here’s an example:
In 3 phase AC power you have line voltages/currents and phase voltages/currents. So when the question asks for the voltage, you are supposed to magically know which one. Now, the voltages/current conversion between line and phase isn’t always the same. Sometimes there is a factor of 1.73. I made extensive equation sheets to help me know when to include the 1.73. I now perfectly arrive at the wrong answer.
Also, anything that references the National Electric Code seems to have a trick to it. Sure, I made some mistakes and learned some things, but on the stuff I knew, I missed a minute detail that screwed me. An example: When looking up the maximum fault current on a 10 AWG wire, I used the appropriate table. I ignored the * next to the 10. the * said not to use the table. It referenced another section of code. I got the problem wrong.
On the plus side, I haven’t thrown a book across the room, yet.
Sincerely,

yeah, I didn't catch any of that. It was all Charlie Brown.
Dude, taht shit's fo real. At least on the one I will take the HVAC part if questions that can be soved by referencing a lot of ASHRAE stuff from their manuals. Got the most recent Fundamentals overview manual, you are so good to go. By the wya, I hate EE, more power to ya Funk, that shits a BEEEEOTTCH
Yes, there is no way in hell i would ever attempt to do electrical engineering. All i know about single and three phase equipment is that the HVAC industry quit manufacturing single phase equipment that is not at least 13 SEER.
