Why is it important to adhere to electrical codes like NEC when installing systems?

Adhering to electrical codes such as the National Electrical Code (NEC) is crucial primarily for ensuring safety and operational reliability. These codes are established to protect people and property from electrical hazards, including shock, fire, and equipment failure. By following these codes during installation, technicians help prevent accidents and injuries that could arise from improper wiring or the use of substandard materials.

Furthermore, compliant installations typically feature proper grounding, circuit protection, and adherence to load calculations, which increase the reliability and longevity of electrical systems. This foundation of safety and reliability is vital, not only for the immediate operation of electrical installations but also for their performance over time, ensuring they function as intended under various conditions without posing risks to users or the property.
