   Number 1: GFCI Protection Requirements [210.8, 2020 NEC]

   210.8 GFCI Protection - https://www.Mikeholt.com/code. There’s no doubt that ground-fault circuit-interrupters have protected many people from electrical hazards. This Code cycle there is an increased emphasis on GFCI protection and many new locations that require GFCI protection have been added. The 2020 changes and revisions to this section are numerous and include clarifications, expansions to existing rules, and a few new items. Some rules were also relocated to and placed in more appropriate articles as indicated in the Informational Notes.

   Number 2: Fire-Rated Walls, Ceilings, and Floors [300.21, 2020 NEC]

   300.21 Fire-Rated Walls, Ceilings, and Floors – https://www.MikeHolt.com/code. Wherever there’s airflow, the potential for a fire to spread exists. The requirements in section 300.21 of the NEC are designed to prevent, as much as possible, increasing the spread of fire where electrical installations may decrease fire-resistive ratings of walls, ceilings, and floors. In this podcast, you’ll learn what must be done in order to comply with this rule.

   Number 5: Equipment Grounding Conductor, Sizing (EGC) [250.122, 2020 NEC]

   250.122 Equipment Grounding Conductor, Sizing – https://www.MikeHolt.com/bonding. The equipment grounding conductor sizes for 15A -30A circuits are easy to remember since they are required to be full sized and are part of cable assemblies. Larger circuits, however, typically require the use of Table 250.122 and that can be a little confusing. Listen to this podcast to better understand how these conductors are sized.
