Hypothetical: Suppose someone had never heard that when upsizing conductors for voltage drop, you must upsize the equipment grounding conductor proportionately according to 250.122(B).
Can you explain the reasoning, importance, and/or need to upsize the EGC?
Does the importance change when using a metallic raceway?
For example, let's say a 20A circuit fed with 10 AWG CU.
Or a 20A circuit fed with 6 AWG CU. Or whatever you please.
Edit: Let us proceed as though "code is code" is not the end-all answer.
I'm going to see if I can let this one roll with no more input from me, but that's never worked before.
