Nice Piece

I really like that this breaker has 0 gauge set screw inputs instead of tiny lugs. I feel much more confident that this unit will not add resistance to the circuit. The mounting tabs are nice and beefy too.

Great Product

I could use a bigger one. Do you make a 350 or 400. It kicks out a lot. I use it on a Ford F-250 Super Duty to help power a 14ft dump trailer. I have to reset it every 30 seconds or so to keep dumping all day.

One of the best circuit breakers!

I love using these circuit breakers when doing an audio system. Upgrading definitely beats using a fuse, especially if you have a secondary battery going into your audio system.
In the event that you have to replace or disconnect your cars main battery you could just easily disconnect your additional secondary sound system battery at a push of a button!
