The minimum conductor size that can be paralleled, according to the NEC is 1/0.

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?
