I'm working in an elementary school changing out ballasts and yesterday noticed that one of my 2 switch legs going into a 4 lamp fluorescent fixture is a size #18 and the other is a #12. Table 310.5 shows that the minimum size is a #14. Why and when is this #18 permitted to be used?
Fixture: 4 Lamp Fluorescent w/ 2 Ballasts
Conduit: 1/2" EMT
Conductors entering fixture: #12 Red, #18 Black, #12 Green, #12 White.
