NFPA 79: Electrical Standard for Industrial Machinery
At the end of this seminar students will be able to:
- Understand where NEC (NFPA 70) stops and NFPA 79 Starts.
- Repair equipment’s electrical components correctly for safety, compliance, and longer equipment use.
- 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.Download Seminar PDF
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
