    Dear NETA. I Passed!!

    Dear NETA,

    A few months ago I posted these questions under the thread **Remembered NETA 2 questions**. After soaking in all input from this forum (thank you to ALL who contributed to my posts) and continuing my education on items I was not that familiar with, I can successfully say I passed your NETA 2. It was a daunting task and my brain hurts from all the information I have gone over the past few months. After my wife almost left me because my head was more concentrated on your standards, rather than her attention, I now understand the concept.
    It truly does take FIELD EXPERIENCE to pass this test. IF you are a new tech to the industry, do not get discouraged if you fail this test once, twice, three times, or in my case, 4 times! It took getting jobs that actually work on the equipment listed to retain the knowledge I finally know. I have been with a NETA firm for 5 years. Before that, I was a journeyman-lineman with an added 5 years. 10 total in the high voltage electrical industry. I had almost given up on the thought of passing this test. However, with patience comes reward.
    You WILL feel like this test is too much! Dear NETA, IT IS!!

    There is no way to your standards that a 2 year man/woman should know the required knowledge to pass this test. I understand I may receive backlash from this, but give us a break. I actually studied more NETA 3 questions than NETA 2 and I feel that is how I was able to pass this test. When these standards were written, it was the technological ice age. I understand they are updated. But so it my IPhone X. Now, every technician is equipped with a computer, smart phone, and all the resources available to him/her so that whatever standard is required, we can easily find the information within a matter of minutes. Can we not come to terms with a society that is so technologically advanced that we can't even consider a vote on "open book" for some tests?

    I have not posted these questions as a "cheat sheet". My integrity and willingness to find this information on my own should show my willingness to thrive in this fast paced, sleep-deprived trade.

    Every NETA company can tell you finding help is scarce, especially in this economy. I urge any NETA member reading this to consider the future of this business. Help us help you. Word on the street is that you revamped the NETA 2 test because one lackluster company was caught cheating. Must we and all future technicians suffer from the mishap of one company? Or can you come to terms with the new age and allow anyone with a drive for excellence and a willingness to learn overcome such a complicated, extensive test?

    Either way.

    I passed. On to your level 3!

    The unit for arc flash is calories per centimeter squared.

    You arrive to find a MV circuit breaker open. At the mechanical switch to the unit, you see the mechanical switch open with a red flag. What would this indicate?

    Someone needs to buy this man a beer for such an open and honest testament. I'm sure many can relate.

    Congratulations on your achievement.

    Fiber Optic Cables and Insulated Cables Question

    The question reads:

    How could you recognize the difference between fiber optic cables and insulated cables?

    I forget the answer options, but none of them really made sense and the correct answer was "fiber optic cables use RJ45 terminations", which is flat out wrong. An RJ45 is used on copper ethernet cables. I have no idea what this question should actually be so I have no idea how to fix it. Was someone trying to remember something they saw (and didn't understand at all) on the exam and came up with this? Was the original question "How could you recognize the difference between fiber optic and ethernet cables?" and the correct answer is "ethernet cables use RJ45 connectors"? Regardless, this question should get overhauled or just deleted.

    Thank You

    You post help alot. I just did my today and pass. 😊😊. I think about 20+ of the question here was on my. They kind of re-word the question a little bit but the answer was like word by word.

    So for people taking there, i said do the testguy quiz. That also help me alot. GL

    This is incorrect. Right from TestGuy "How Electricity affects your body"

    'Ventricular fibrillation occurs with currents as low as 60-100 mA in AC systems. For DC, about 300 to 500 mA.'

    Based on your experience with the level 2 test, how did your level 3 test go sir?
