In NEC article 300.37, it states that exposed busbar may be installed in areas that are accessible to qualified persons only. Does this imply that this given area must be enclosed or fenced off in some manner? Also, is there any specific provision for corrosion protection for exposed copper busbars - I couldn't find any line that addressed this directly. Thank you.
