Doesn't a #4 awg fall under the exact same category as a #6 awg? Both require conduit if exposed to physical damage. Assumption: all gec conductors larger than #8 can be run on surface without conduit if not exposed to physical damage. It appears repetitive and confusing.
it is a judgment call if you knowingly see its location. Think if it is exposed to damage yes protect it but if it is secured correctly and not in the path of being damaged yes it doesnot have to be encased or protected that is what the code is trying to say my friend.
"4 AWG or larger copper or aluminum grounding electrode conductor" doesn't even need to be mentioned. The reason #4awg is mentioned is because in the 2002 Nec a #4awg only required protection when exposed to"severe" damage, the word "severe" was taken out in 2005. The whole sentence should have been taken out. This is interpreted differently by local AHJ's.
