NEC Article 110 covers which of the following?

NEC Article 110 outlines the general requirements for electrical installations. This includes the fundamental safety practices and conditions necessary to ensure that electrical systems are installed and maintained in a safe manner. It addresses various aspects such as the adequacy of electrical equipment, clearances, and the environment in which electrical installations are made.

Understanding these general requirements is crucial for electricians as they serve as the foundational guidelines for safe electrical work, ensuring that systems not only function correctly but also adhere to safety standards that protect both the installation and the people who will use or come into contact with electrical systems.

The other options refer to more specific parts of the National Electrical Code (NEC). Grounding and bonding, for example, is covered in a different article dedicated solely to those principles, while residential wiring and wiring methods are also described under distinct sections for clarity and focus on those specific aspects of electrical installations. This differentiation allows electricians to reference the exact guidelines needed for various types of work.
