Colorado – NEC 2023 – Theory and Calculations

This course covers the essential calculations and theoretical principles required for sizing and protecting electrical systems under the NEC 2023 code. You will review the rules for determining conductor ampacity, permissible branch circuit loads, and the specific requirements for lighting outlets and kitchen island receptacles. The curriculum details critical load calculations for diverse environments, ranging from standard floor area and receptacle loads to specialized applications for marinas, boatyards, and Electric Vehicle Supply Equipment (EVSE).

Beyond basic circuit sizing, the training focuses on equipment ratings and system capacity. You will examine the requirements for overcurrent protection, including selective coordination, breaker ratings, and the use of copper-clad aluminum conductors. The course also addresses complex calculations for motor ampacities, HVAC equipment, and fire pump voltage drop, alongside the capacity rules for emergency systems, feeders, and energy management systems, ensuring you can accurately determine the requirements for both every day and critical power installations.
