I know y do it , but why !
When running alternating current you run solid wire , when running direct current you run stranded . Why ?

If I remember my intro to electrical engineering in ac current flows thruout a conductor. With DC current follows the skin of a conductor, stranded wire provides more skin aka surface area than one solid conductor. However I'm sure others who really know about this will reply....
Sorry, but that's reversed. The "skin effect" applies to AC, not DC. Wires of the same AWG have exactly the same total cross sectional area and can carry exactly the same current. Note that wire ampacity tables do not differentiate between single and multi-core wires.
