Can anyone offer their opinion for what cable sizes are excessive that I should avoid using and thus opt to run multiple sets of cable?
Suppose I have a building with a 480Y/277V 600 Amp Service.
Using Table 310.15(B)(16) is it better to run
4# 1500kcmil?
or
2 sets of 4# 350 kcmil?
I would opt to not use #1500kcmil cable but I'm not sure where the cutoff I should opt to use multiple sets occurs.
Any thoughts?
