I have a motor feeder that is 2/0Cu, 3 conductor (bundled), UL MV-90, non-shielded in Ethylene Propylene Rubber (EPR) insulation. I need to size the conduit for this feeder (Rigid metal conduit). I know that NEC Ch9 Table 1 gives me my allowable % conduit fill, and that Table 4 gives a cross...

I have heard really good things about Test Masters. The only reason that I didn't take it is that I live in Beaumont approximately 2 hours away. I did take the Irvine course and pass (about $700 with books). It is all online and really helped me be efficient. Like Cable Guy said, it is mostly...

I took the Irvine course and passed. It is definitely more than just the Chelipati book. Several of the topics are covered by notes made by the instructors. The main advantage I found to the course was efficiency in studying. However, the Irvine course does fall short in several areas. The two...

As stated above, I am feeling much better about the NEC. I pushed through my avoidance behavior ... still a beeeeeech! I have worked all the problems except for the Kaiser 137. Could you email me that if you have time? [email protected] Also, I have added your tab suggestions to my...

After spending much of the weekend with the code, I am feeling much more confident. Thanks for the link to Holt's index. It is now in my binder.

I had to quit for the day. I have found my weakness and it is the NEC. I don't want to look at that code any more. Feel free to express your woes with the CODE.

Cable guy: I saw this post today. Out of curiosity, what would be the solution to your stated example?

Problem Statement: The design for a transformer secondary calls for #14 gauge copper wire with a 2.7ohm/1000ft resistance according to the NEC. The max current drawn by the electronic bias power drawer is 3amps, powered from the secondary of the transformer. The allowable voltage drop is 7.6v...

I have some old NEC practice problems. Problem: What is the general lighting load for a 4000 square foot bank? Answer: From table 220.12 the general lighting load by occupancy of a bank is (3.5 va/sqft)*(4000 sqft)*(1.25) = 17,500va. My question: In NEC article 210.19(A)(1) it states to...

I need help understanding this differential relay problem. Problem Statement: A three phase, delta-wye-connected, 30MVA, 33/11kv transformer is protected by a differential relay. Calculate the relay current setting for faults drawing up to 200 percent of the rated current. The CT ratio on the...

I never got a copy of this exam. It may not be much help to me anyway since it does not focus on only power. Sorry.

You can register for the lectures at http://www.irvine-institute.org/ After you register, you will gain access to past archives so you can begin going through old lectures now if you like (fall classes do not begin until the end of summer). Also, I am in TX, so the California class times were...

All you really need is volume 1. This only covers the Power exam. Chelapati recommends you to buy a section of Volume 2 for power electronics, but it was fairly useless to me. I would recommend finding an alternate reference for power electronics. Also, I would recommend the lectures. They...

I will preface this statement with the fact that the TI89 was my go to calculator in college. It served me well. I naturally gravitated towards the TI-36X when I began my FE preparation, and it did its job while I passed on my first try. I ran into much frustration, however, with the TI-36X in...

I am taking the PE Electrical Power Exam in April. Does anyone know of any good practice exams to use. I already have the following: 1. NCEES Practice Exam 2. Camera Practice exam. Please let me know. Thanks.
