I was working on some existing lights in a building. They are suspended from a drop ceiling with steel cables and connected end to end. Each lighting circuit is 20 amps, 277 volts. The lights are fed with 12/2 MC cable to a junction box and then a rubber cord (16 awg) from the box, down to the fixture. The wiring through the fixtures is 18 AWG. My question is - Is the 18 AWG wire between the fixtures legal, or should it be 12 AWG wire per the 20 amp circuit? Thanks.
