This self-paced online course covers requirements for wiring methods and devices in the National Electrical Code. The course covers the physical items that carry electrical current from one place to another and that serve as the actual interface with the user.
Upon completion you should be able to:
- Explain the distinction between wiring devices and wiring methods.
- Identify the general requirements for wiring methods in the NEC, including:
- separation of conductors.
- protection from physical damage.
- protection of underground wiring.
- protection from corrosion.
- Explain requirements for securing and supporting wiring methods.
- Explain requirements for locating boxes.
- Describe requirements for raceways.
- Identify requirements for selecting wiring methods.
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.
- Wiring methods and devices are the physical items that carry electrical current from one place to another and that serve as the actual interface with the user.
- NEC Article 300 covers general requirements for wiring, and other articles provide specific requirements.
- There are a number of general requirements detailing when conductors of certain types and power levels are kept together and when they are separated.
- Wiring must be protected from physical damage and corrosion. Wiring methods also must be secured and supported in ways that do not damage them or compromise their function.
- General requirements also address where boxes are located and how conductors are handled inside them, as well as how conductors are handled inside raceways.
- The selection of wiring methods is addressed in several sections and articles and may depend on the uses permitted and not permitted for a given wiring method as well as any specific restrictions related to the occupancy.
