[QUOTE="knukonceptz, post: 1305628, member: 548221"] Keep in mind gauge, current, and length of run must all be considered. I think 120A is the most I would put to a 20 ft section of 4 gauge. Using the standard AWG rating for 4 gauge cable (Dia = 5.18922mm) at 120A on 20ft you would have a 1.4V loss with 12VDC. At the same time, unless you are competing you will probably not ever draw the max of all your amps at the same time. Here is a fun little calculator to show loss using standard AWG cables.
