Message: <blockquote data-quote="HardofWhoring" data-source="post: 8845722" data-attributes="member: 674149">300a fuse is too much for 4awg wire.   The point of the fuse is to intentionally be the weak point in the circuit.   300 amp fuse on a 4awg wire, and your 4awg wire becomes the fuse.   The fuse on the wire is for the wire, and needs to be capable of more than the load, but less than the capability of the wire.   That right there is caused by resistance at a connection not being tight enough.  It didn't happen at any other point in the wire, and it didn't happen at the fuse.  It happened where the connections weren't tight enough.  THAT or you cut too many strands off that wire when you cut the sheath away.   Am I wrong or does that burned up wire look like CCA?</blockquote>
