2021 International Residential Code, Part VIII

Residential Electrical Code

The electrical provisions of the 2021 IRC, which follow the 2020 National Electrical Code, taught for residential inspection and for GCHS rehab and construction management work: services, grounding and bonding, branch circuits, receptacles, GFCI and AFCI protection, wiring methods, boxes, panelboards, devices, appliances, pools and spas, and existing wiring in older homes. 14 lessons and a 60-question practice exam, self-paced.

About this course

Independent GCHS training

Each lesson has a dimensioned diagram, a glossary, 14 practice questions (20 in Lesson 14) and neural narration. Numbers were checked against at least two public sources. In Texas the NEC is adopted statewide, cities adopt editions and local amendments, and electrical work must be done by TDLR-licensed electricians, so always confirm the edition and amendments in force where the work is permitted. This is training, not a substitute for the adopted code.
