Burning up my wire..help!

[KyleBrown 121]

I have some CCA wire under the hood. No issues.

But I don't run fuses

Yea it's the cheaper of knu's cable. Rated for 250amps is what it says. Too much current? What's the fix for this?

OFC.

it's not the wire!

CCA 1/0 from Knu is rated to handle up to 350A @3ft.

If it were the wire, the melting wouldn't be isolated to just one side of the fuse holder...

Like someone else said earlier, if you are using set screws.. they have tendency to allow your wire to loosen over time due to vibrations.

This is ALSO TRUE for amps too if the amp isn't mounted securely enough.

Solution- mount fuse block(zip tie is fine too) and zip tie the power wire within 1-3" from each entranceexit point to something to ensure it's "locked" in place.

Other alternative, ditch set screws and go all terminal only.

I changed the holder to a ring terminal type. Replaced everything. So far so good
