Intended Audience

The intended audience is professional electrical engineers, project managers, and project engineers, involved in the installation, operation, or maintenance of electrical supply and communication lines and associated equipment.

Benefit to Attendees

Provide a professional development course that covers the rules and requirements used to safeguard personnel during the installation, operation, or maintenance of electrical supply and communication lines and associated equipment.

Course Introduction

This course presents the rules for the practical safeguarding of persons during the installation, operation, or maintenance of electrical supply and communication lines and associated equipment.  These rules contain the basic provisions that are to be considered for the safety of employees and the public under the specified conditions. The course is intended to (1) provide the rules that cover supply and communication lines, equipment, and associated work practices employed by a public or private electric supply, communication, railway, or similar; (2) describe the responsibilities of the utilities, authorized contractors, or other entities, as applicable, performing design, construction, operation, or maintenance tasks for electric supply or communication lines or equipment covered by this Code.

The course materials are based entirely on the “National Electrical Safety Code C2-2017.  It will be necessary for the student to obtain a copy of the “National Electrical Safety Code C2-2017 or have access to a copy of this code.  This is a very useful resource and is recommended that all practicing electrical or project engineers involved in electrical supply and communication lines and associated equipment engineering and design, construction, or maintenance should be familiar with and up to date with the rules provided in this code.

Course Content

These rules contain the basic provisions that are considered necessary for the safety of employees and the public under the specified conditions.  The purpose of the rules is the practical safeguarding of persons during the installation, operation, or maintenance of electric supply and communication lines and associated equipment.  The course is not intended as a design specification or as an instruction manual.  You are required to obtain a copy and study the “National Electrical Safety Code C2-2017”. The NESC is a useful reference tool that every practicing electrical engineering professional should have access to.
