NFPA 79: Electrical Standard for Industrial Machinery

$899

Lecture

2 Day

1.6 CEU

At the end of this seminar students will be able to:

  1. Understand where NEC (NFPA 70) stops and NFPA 79 Starts.
  2. Repair equipment’s electrical components correctly for safety, compliance, and longer equipment use.
  3. Understand equipment design so maintenance tasks (procedures) can be more effective.
  • Why You should take this seminar

    The goal is production equipment uptime and reliability. This course is for you if your team maintains or repairs the machine electrical controls for your production process.

    The NEC (NFPA 70) addresses how that equipment can be electrically installed; but the NEC stops at the outside of the piece of equipment. NFPA 79 picks-up INSIDE the equipment and addresses HOW the wiring and grounding of the actual piece of equipment is done.

    When the equipment does need maintenance or repair, you need to understand why the electrical controls and components were designed and installed the way they are so you can keep it that way.  Ultimately you should experience:

    • less down time due to improperly maintained equipment, and
    • will also understand ‘why’ reoccurring problems are happening, and be able to fix them once and for all.
    • more effective maintenance tasks (procedures)

    If you are moving equipment, you may be required to upgrade the internal electrical system to comply with current standards.

  • Who Should Take This Seminar

    If you work on electrical systems, you should understand the recommended best practices for maintaining them. Maintenance, Operators, Supervisors, and non-qualified workers will benefit from this training.

    People who work on and around industrial equipment will benefit from this course including:

    • Safety directors
    • Electrical contractors
    • Maintenance electricians
    • Owners & Managers
    • Supervisors (working on or who oversee employees working on 50V or greater equipment)
    • Plant & facility maintenance technicians
  • What You'll Learn

    Individuals will learn the scope of the NPFA 79 and understand its unique guidelines for electrical installation and sizing as compared to other codes.  How to maintain electrical industrial machines without compromising safety or efficiency by repairing and replacing parts with the full understanding of the standard requirements.

    Training includes:

    • Understanding the scope of NFPA 79 – what it is and is not.
    • Understanding how NFPA 79 interacts with other standards.
    • How to effectively use the Standard as a guideline for wiring, sizing conductors and overcurrent protection for industrial machines.
    • Learn preventative maintenance for equipment and systems.
    • Safety techniques and knowledge for protecting yourself and the equipment from electrical hazards to grounding and more.
    • What NFPA 79 says about electrical wiring and controls within OEM Equipment.
      • Why things are designed the way they are?
      • Why the equipment is assembled the way it is?
      • Expectations about Maintenance of Electrical Parts of Machine?
  • Seminar Description
