Which code should be referenced for proper installation of attic lighting among equipment?

The correct reference for proper installation of attic lighting among equipment is found in Section 210.70(C) of the National Electrical Code (NEC). This section specifically addresses the requirements for the installation of lighting in attics, which ensures safety and compliance with electrical standards. It outlines necessary provisions for lighting in attics, including requirements for spacing and switching, to ensure that these spaces are adequately illuminated for safe access and maintenance.

ISO 9001 pertains to quality management systems and does not specifically address electrical installation standards or lighting requirements. OSHA standards focus on workplace safety regulations but do not delve into the specific details of electrical installations or attic lighting. NFC regulations, likely referring to the National Fire Code, relate to fire safety and prevention, but they do not provide detailed guidelines regarding electrical installations. Therefore, Section 210.70(C) of the NEC is the most relevant and authoritative source for proper attic lighting installation.
