10.0809 is a section of the National Fire Protection Association’s (NFPA) fire safety standard, NFPA 70: National Electrical Code (NEC). This section specifically covers the contact requirements for an orange and yellow electrical wire that is used as a wiring interconnect, usually between two pieces of control equipment or between a piece of control equipment and the load it is controlling. Specifically, it covers requirements for making secure, permanent connections using both metal or nonmetallic (plastic, rubber, etc.) wire connectors, as well as how wiring should be routed to avoid creating a hazardous situation. The code also outlines how to inspect for a secure connection, as well as testing requirements for verifying a robust contact connection.
