iahim, Your final response is exactly the case. None of the previous responses were correct at all. Per the NEC 240.4(B), you are allowed to select the "next size up" when certain qualifications are true. Since you are not given details on these qualifications, you can not assume that they are...

Can you post the question?

I just passed the Power exam, but I would have loved to see a diagnostic report as well. I don't understand why they aren't included with all of the exams. I do remember seeing a guide on how to read those on the NCEES site somewhere.

Passed Power in Oklahoma!

I am a consulting engineer for a firm that does MEP design (Mechanical, Electrical, and Plumbing) for construction projects. I am really happy where I am at, but I have been advised by a mentor to check out what is available in the local oil and gas type companies such as Sandridge, Chesapeake...

High property taxes are a big source of funds in Texas.

I, too felt that the afternoon of the Power Exam was one curve ball after another. Many questions were really foreign to me, but I felt like i was able to plug and chug my way through the majority once I just started using my formulas with the variables that were given. I initially skipped about...

Oklahoma.

I started seriously studying in December of last year. I started with the NCEES practice test. Once I worked through about half of it, I started to get really worried because much of it was so foreign to me. Then I started gathering resources and reading up on a lot of old concepts and...

I nearly wrote in my binder of notes, but caught myself just short. I was in the front row right in front of the proctor who was watching me. She went to get up as I placed my pencil on the sheet. As soon as the led touched the paper, I quickly jerked it back up, and she sat back down. Just a...

It sure is nice to have the test behind me for awhile. I can't wait for the results to come back. I'm confident that i passed, but that doesn't make me any less anxious. How did everyone else feel like they did?

NEC does have their own values, but they are not cut and dry, and they vary per article depending on how they're used.

The answer to that is a bit muddy, and depends on if you're speaking of wiring or gear. I don't think you'll find a clear cut answer. IEEE has a more defined standard, but they classify low voltage as 600V and below, which ignores the NEC's separation of wiring that is <24 volts.

Do any of you believe that this is a topic that will be covered on the exam?

NASIR, Each conductor (both coming and going) has the 200 ohm impedance. Effectively the power dissipated is: P= (5^2)200 + 800W + (5^2)200 or P = (5^2)(200*2) + 800W
