I have a light tower and emergency stop button mounted 50 ft from the system enclosure. The current for the light tower is 300mA at 24VDC. I want to use a 20 AWG multiple conductor cable in a raceway to connect the light tower and button to the system enclosure. NFPA 79 12.6.2 states control circuit conductors shall not be smaller than 16 AWG in a raceway and 18 AWG when using multiconductor cable. NFPA 79 12.6.4 states conductors for electronic control input/output and control devices shall not be smaller than those permitted in 22.214.171.124 and 126.96.36.199. 188.8.131.52 states conductors installed in raceways shall not be smaller than 24 AWG. I am not sure what the distinction is between 12.6.2 and 12.6.4. Does my circuit meet 12.6.4 criteria?
Thanks in advance for you help.
