Minnesota Electrical Journeyman Practice Exam

Air-conditioning and refrigeration equipment is covered by Article 440. This article specifically governs the installation and wiring of HVAC and refrigeration equipment, including requirements for conductors, overcurrent protection, disconnecting means, motor controllers, and control circuits. It addresses the safety and proper sizing needed for outdoor units, condensers, compressors, and related components, ensuring that HVAC systems are wired and protected correctly. The other articles cover different topics: one focuses on general conductors, another on service conductors and service equipment, and another on transformers, so they don’t directly apply to the installation and safety rules for A/C and refrigeration equipment.
