This is a two-part course. Part one covers Chapter 6 and 7 of the 2020 National Electrical Code®. Chapter 6 contains requirements for special equipment, and Chapter 7 contains requirements for special conditions. Several changes were made in the articles for photovoltaic systems and interconnected electric power production sources. Notable changes include changes to PV overcurrent protection, disconnecting means, and language for interconnection of electric power production sources.
Part two of this interactive online course covers new definitions added, and existing definitions that have been revised or relocated in the 2020 NEC®. We also review new and revised requirements for equipment installation, labeling, marking and working space.
After successfully completing Part 1 of this course, you will be able to:
· By the end of this course, you will be able to:
· List the three ways voltage is calculated for PV systems.
· Identify how current is calculated for different PV system circuits.
· Identify where overcurrent protection is required in PV system circuits.
· Recognize the rules for multiconductor cables in PV system circuits
· Size equipment grounding conductors for DC and AC circuits in PV systems.
· Recognize the marking requirements for buildings with PV power sources.
· Identify the rules for supply side source connections.
· Identify the requirements for power control systems.
· List the basic requirements for power source disconnecting means.
· Identify circuit sizing and overcurrent protection requirements for power source circuits· Identify basic elements of micro grids.
After successfully completing Part 2 of this course, you will be able to:
- Explain the NEC Style Manual including the rules for definition placement
- Discuss new Part III of Article 100 Definitions
- Describe the new definitions related to dormitory units, island mode, laundry area and reconditioned
- Describe the revisions to existing definitions of accessible, available fault current, equipment grounding conductor, equipotential plane and labeled
- Identify the revision at Section 110.5 Conductors related to copper clad aluminum, Section 110.14(D) Terminal Connection Torque, Section 110.22(A) Identification of Disconnecting Means, and Section 110.24(A) Field Marking Available Fault Current
- Recognize the revisions to under 1000 volt working space requirements in Sections 110.26(A)(3), 110.26(C)(2) and 110.26(D) and to over 1000 volt working space requirements in Sections 110.31(A)(4) and 110.32
- Explain new Section 110.12 Cables and Conductors and Section 110.21(A)(2) Reconditioned Equipment
