Course Outline – 8am-4pm
8am-12pm: Power Quality and Energy Management
12pm-4pm: 2020 Code Changes
The 2020 NEC introduces sweeping revisions for both safety and in meeting the evolving demands of power created by new and affordable technologies. This morning portion of the course covers corrective and improved action prompted within the code. By reviewing fundamentals of what an electrician needs to know to meet the higher levels of efficiency within the individual parts of the A/C system, this section will address the electrical system from Article 210 and working in to the service, as directed by the National Electrical Code.
