10 Exam Questions to Get You Started

When preparing for the master electrical exam or the journey electrical exam, it helps to see the questions as they are formatted in the real exam.  Now, obviously we aren't able to show you the exact question that is on the actual test, but you do get the formatting and the content as it is outlined in the exam candidate books.
Today we are sharing 10 exam questions to get you started on your ICC or PSI exam.  Some may seem very obvious and easy but don't forget, they add the wrong answer in the multiple choice in case you calculated wrong.  

Make sure to time yourself when taking this mini test and see if you can answer each question in under 3 minutes.  Don't forget, the real exam is time giving you an average of 3 minutes per question.

Make sure to check back next week for the answers, or if you don't want to wait that long, sign up for our newsletter and we'll send you the answers by email.

Electrician Candidate Information Bulletin

Good Morning, Today we received a call from someone asking us the phone number to the PSI so they can change their appointment.  While we don't do the actual exams here, we are more than happy to help :)  We put together a cheat blog with the link to the ECIB , Table of Contents, FAQ's, and some shameless marketing for our seminars and books.  (I'd be a terrible business person if I didn't add a couple of sales links ;) Feel free to share this page with any Texas electrician preparing for their exam. This will come in handy. The Electrical Candidate Information Bulletin can be found here .  You may download and save it, print it or just read it online. Make sure to bookmark this link so you can refer to it during your studies.
