Solid ground: Increasing parallel conductor ampacity

The most popular reason for paralleling conductors is to provide higher ampacity than a single conductor can provide. "In a typical building design, the largest conductors are usually 500 kcmil or 600 kcmil". "And many electrical contractors will actually object to 600 kcmil. If ampacity above 400 A is necessary, using parallel conductors is the only reasonable solution.
