What should you consult when making adjustments in electrical systems?

Consulting the manufacturer's manual when making adjustments in electrical systems is crucial because it provides specific instructions and recommendations tailored to that particular equipment or system. This manual contains valuable information regarding the operational parameters, recommended maintenance practices, and any adjustments that can safely be made. Following the guidance in the manufacturer's manual ensures that adjustments are made correctly and safely, thereby reducing the risk of equipment failure or hazards.

Local codes and guidelines are also important, as they ensure compliance with regional safety and building requirements. Standard operating procedures outline general practices for operation and safety but may not address the nuances of specific equipment. Safety regulations provide overarching safety standards but do not typically offer the detailed guidance needed for particular adjustments. Hence, while all these resources play valuable roles in the overall process, the manufacturer's manual serves as the most direct and relevant resource for making adjustments to electrical systems.
