65 amp breaker, #6 wires with #8 EGC, running from j-box to j-box along the ceiling. At each j-box, smaller wires are tapped and run (less than 10 feet) to a fused disconnect and then to an adjacent VAV box. For example, #12 wires to 20 amp fused disconnect. Question: what size EGC do you run with the #12s? I have my own answer, but I am looking at some plans with a different answer.
