Tech Tip

Although the maximum fuse size this block takes is 400 Amps the recommended maximum operating current is 320 Amps for general use or 300 Amps if used in an engine space.  To be able to run at this maximum operating current the cable size required for continuous duty is 2 x 4/0 awg in an engine space. This is because the cable is required to help remove any heat buildup.
