A rule of thumb for bus bar design is to not allow the current density to exceed 5A/mm2 . A higher threshold would mean that a smaller cross sectional area is needed, allowing for a size reduction in the vertical or horizontal directions. A lower noise, which is pushed to the surface to travel through the lossy nickel due to the skin effect.
