Specific Equipment Part II
Continuing Education Units (CEU): 0.10
Expected Duration: 1 Hour
This self-paced online course is the second of three covering specific equipment addressed in Chapter 4 of the NEC. Chapter 4, titled "Equipment for General Use," covers a very broad range of equipment.
Upon completion you should be able to:
- Identify some of the most commonly applied articles of NEC Chapter 4.
- Identify key terms, requirements and places in the Code that address specific types of luminaires.
- Explainhow appliance requirements apply to central heating equipment, water heaters, flexible cords and disconnecting means.
- Identify which types of equipment are covered by NEC requirements.
- Regarding fixed outdoor deicing and snow-melting equipment:
- Why this equipment will be treated as a continuous load.
- Why ground-fault protection for equipment (GFPE) is needed.
- The similarities and differences with fixed electric heating equipment for pipelines and vessels.
Who Will Benefit
Anyone whose job involves designing, reviewing, evaluating or installing fire protection systems, including: designers, installers, engineers, electrical contractors, technicians, project managers, fire marshals, and architects.
- Lighting equipment covered in Article 410 includes lamps (often called light bulbs), as well as lampholders and luminaires, which must be listed.
- There are specific requirements for luminaires in certain locations, as well as requirements for luminaire support.
- Specific types of luminaires are addressed in Parts VIII through XV of the Code.
- Appliance requirements (Article 422) cover listing, branch circuit ratings, flexible cords and disconnecting means, as well as addressing how appliance requirements apply to central heating equipment, water heaters.
- Requirements for fixed electric space heating equipment (Article 424) cover a wide variety of equipment, but not process heating and room air conditioning. Branch circuit and overcurrent requirements are covered in this module.
- Article 426 includes very specific requirements for fixed outdoor deicing and snow melting equipment, including some that are unique to this type of equipment. Circuits for these types of equipment are treated as a continuous load and require ground-fault protection for equipment (GFPE).
- Fixed electric heating equipment for pipelines and vessels (Article 427) has similar requirements, but there are are some differences. For example, because this equipment is often installed on the outside of a pipe or vessel but underneath insulation, there are labeling instructions to help avoid accidental damage.
