Introduction

Basic Electricity Test Study Guide Skill and Knowledge Checklist

Overview

This Study Guide is designed to familiarize you with the basic electricity knowledge and skills required by BellSouth’s technical jobs and covered by the Basic Electricity Test. It will also familiarize you with the test, help you decide if you’re ready to take it, and guide your preparation if you’re not ready at this time.

What does the Basic Electricity Test cover?

It covers four main subject areas: • Electricity Fundamentals
⇒ Electrical Concepts ⇒ Schematic Reading ⇒ Circuit Measurements ⇒ Circuit Identification • Alternating Current and Reactive Elements • Safety and Protection Devices • Multimeters In addition, you need to know: • Applied Math

What exactly do I have to know?

Here is a list of the specific things you should know and skills you should have in order to perform a job that requires a background in basic electricity. If you know and understand these things and can apply what you know, you should do well on the test.

What Does the Checklist Tell Me?

Basic Electricity Test Study Guide Skill and Knowledge Checklist

So, you knew it all…

If you checked off ALL of the items on this list, then you probably have the skills and knowledge for any job that requires passing the basic electricity test. We still recommend that you take the practice test in Section 3. If you do well on the practice test, then you should sign up for the actual test.

So, you knew most of it…

If you checked off most of the items on the list, you should concentrate on what you DID NOT check off. Buy or borrow one of the resource books listed in Section 4, Page 8 and review it to see if it answers your questions. If you feel that your self-study session brought your skills up to par, take the practice test. If you do well on the practice test, then you should sign up for the actual test.

So, you only know some of the topics…

You probably need some additional training and education even before you take the practice test. If you’re a regular full-time or regular part-time employee with at least six months of seniority, you are to participate in services offered through Employment Security PARTNERSHIP and should look at Appendix A for options. If you’re not eligible for such training, then look at Appendix B for information about obtaining further education outside of BellSouth.
