[RE-wrenches] Parallel Wire combining

[Bill Turberville]

The ampacity is twice the ampacity of 1-1/0 conductor under the same
conditions.

OK, let's use 1/0 for the example. 108,350 x 3 = 325,050. Do I now have a
cable between 300 and 350 AWG?

Thank you,



Larry

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
