We have installed multible mcm 500 to meet this and there were three on
each leg but that was because of the required size and bending room

Wrenches,

If I combine 3 conductors of equal length in parallel, is the resulting
size equal to 3 times the Circular Mil area? For example, #4 is 42,080cm so
are three #4's close to 2/0 (134,200cm) in size? Is it as simple as this?
Assuming the conductors can not be removed individually, does this mean the
current capacity is equal to the resulting wire size?

Thanks, Larry
