Texas Electricians- The End is Near- How to Avoid Getting Lost in the Shuffle

How to Avoid Getting Lost in the Shuffle If you haven't heard that the end of the 2011 NEC Exams is coming up, then you've been living under a rock or working way too hard. That's right guys, if you have applied to take your exam but have not yet passed or even taken the exam, you have a deadline.  As of September 1, 2014, the TDLR will only accept and recognize the 2014 version of the  National Electrical Code ®  on the field and in the testing site.  The exam will be based on the 2014 version of the book, you will still be allowed to bring in your 2011 but we do not recommend that.  If you already have your 2014, you must have already noticed that there a great deal of updates on the code.  Your first clue should be the number of pages, the book has gotten BIGGER! We have the last few seminars already lined up, there is limited seating and I strongly recommend that you reserve a seat.  Alternatively, if you don't have time for a seminar and...

Formulas to study for the electrical test

The formulas to study for the electrical test range from common knowledge (those you use on the field) to complicated.  Let’s go over the commonly needed formulas that you will need to use for the PSI electrical test. To download our Electrical Formulas Cheat Sheet, click here . Includes motor calculation steps, box fill, ranges, transformers, conduit fill, PIE, EIR, and more! If your testing center allows short notes in the code book, write these formulas down. This way you don’t have to try to remember them during the test. Check your test provider’s website to see if they allow short notes in the book. For those who are not allowed to have written notes in the book, make yourself some flash cards and memorize these formulas. Formulas to Study for the Electrical Exam PEMDAS Even though PEMDAS is not an electrical formula, you must remember your order of operations. Don’t go through the trouble for learning these fo...
