And a fine point….
There are two types of AWG wire: Boat Cable and SAE. SAE wire of the same size (e.g., 2/0) has generally about 12% less copper than true Boat Cable.
The way I learned it in tradeschool, there are two types of boat cable, AWG and SAE. AWG has more copper for the same size. Make sure when you are comparing prices that you are comparing apples to apples. The ABYC tables are for AWG wire.
